Soeks-01M Geiger Counter, English Display & Manual £189.00 inc UK p&p

The Soeks-01M is one of the smallest and most sophisticated pocket Geiger Counters we've seen. We could wax lyrical about the small size, neat design, super sensitive Geiger Muller tube (incidentally, it's the same SBM-20 type as used in the Radex 1503 and 1706 models) and smart colour LCD display but rather than witter on we'll let the specs speak for themselves. Just take a

look at these features:

Beta, Gamma X-Ray sensitive

Colour TFT display (4 colour themes, variable brightness & always on/time out)

Three independent display channels:

Numeric in microsievert/hour or microroentgen/hour

One minute trend, graph

Visual colour code normal/high/danger

Audible event and alarm bleeper (3 volume setting)

User preset alarm level

Dual language on-screen display (English & Russian)

USB charger socket (for optional recharge batteries)

Powered by 2 x AAA cells (10 hour operation)

Operating temperature range °? -10.+50

Weight 62g (with batteries)

Dimensions mm 120 × 52 × 26mm

Still not impressed? Well, for those interested in performance take a look

at this little lot:

Indicated range 0.003 - 100uSv

Gamma radiation equivalent dose rate (137Cs) µSv/h 0.1 - 999.9 ±25%

Gamma radiation equivalent dose (137Cs) mSv 0.001 - 9.999 ±25%

Energy ranges of measurement and energy dependence:

Gamma radiation MeV 0.05 - 3.0 MeV ±25%

Beta radiation MeV 0.5 - 3.0 MeV

Measurement time interval seconds 5 - 70 seconds

To sum up, the LCD screen gives a constantly updated numerical readout in microsieverts (or microroentgens) plus a colour-coded graph display that shows the relative activity over the previous minute, and a colour coded alert panel that indicates normal, high and danger. It has an audible bleep in response to detected ‘events’ and there’s a user-programmable alarm to alert you if the levels exceed a preset threshold. It runs on standard AAA cells, or you can use re-chargeable cells, and charge them through the mini USB socket on the base (USB lead and two rechargeable batteries included). The simple to use on-screen menu lets you change the screen brightness, backlight timeout (or set it for always on), colour theme, change menu and display language and, lastly, set the alarm threshold.

Radex RD1503 Geiger Counter with English display & manual, £199.00 inc UK p&p

The Radex RD 1503 is extremely sensitive, easily registering natural background radiation, and highly accurate, with the 42mm backlit LCD panel giving constantly updated and averaged readings (in 10 second cycles) of exposure to a wide range of Beta and Gamma radiation. It is calibrated  in micro Sieverts or micro Rem per hour, switchable using the on-screen menu. This also controls the variable volume bleeper and setup options, plus a level control which lets you program the bleeper threshold to 0.3, 0.6 or 1.2 uSv/hr (30, 60 or 120 uRem/Hr).

The RD 1503 is sturdy, very well built, and remarkably easy to use, with just three buttons, for switching the unit on and off, switching the backlight on and navigating the on-screen menus. It’s compact too, measuring just 100 x 60 x 24mm – around the size of a pack of 20 cigarettes -- and it weighs just 90 grams, so it slips easily into shirt or trouser pockets. It is powered by one or two AAA cells, which can run the unit continuously for up to 550 hours (over 3 weeks!).

For the technically minded the range of measurement is from 0.05 to 9.99uSv/Hr (5 – 999 uRem/hr) and the gamma range is 0.1 to 1.25MeV.

blueGeiger PG-15 Geiger Counter with Bluetooth,

NEW Lower Price  - £309.99 inc UK p&p

NEW Windows/Excel Compatibility

Here’s something you don’t see every day: in fact it’s a first - a compact Geiger Counter that links to your Android smart phone via Bluetooth, taking personal radiation monitoring to a whole new level.

We are proud to present blueGeiger PG-15 and before we get to the exciting new Bluetooth options we’ll run through the headline features.

It’s a small standalone device, a little larger than a pack of 20 cigarettes so it slips easily into a pocket. It is really simple to use with just three buttons that cover all menu, function and mode selections. Sensitivity is excellent; it can accurately determine normal background radiation levels and responds quickly to elevated levels of beta, gamma and X-Ray radiation, with the first reading appearing in under a minute.

Readings and menu options are shown on a large (44 x 28mm) backlit LCD display. This shows the current activity level in the range 0.05 to 300 uSv/h (microsieverts/hr) and there are icons for event detection, alarm status, battery level and mode. The user-set alarm has three preset levels of 0.3, 0.6 and 1.2 uSv/hr. A built-in sounder (5-step volume and mute) clicks or bleeps with every detected event and when the alarm threshold is exceeded. It is powered by one or two AA cells, which can last for up to 60 hours (depending on battery type and functions selected). It’s housed in a tough polymer case with rubberised grip edges and for a limited period it will be supplied with free batteries.

Now for those unique Bluetooth features. Once you’ve downloaded the free Android app from the Android Market (search Kindenoo) your smart phone will operate as a remote monitor for blueGeiger, displaying the continuously updated reading in microsieverts/hr, with the facility to capture and store spot readings. It also shows other useful items of information, such as your location (if enabled  fon your smartphone) and blueGeiger’s battery level.

That’s pretty impressive but here’s the really clever bit. Your readings can be uploaded to the web and displayed as a colour coded map overlay, graph and table, creating a permanent record of the activity levels in the locations you have visited. Over time this data can be used to create comprehensive radiation maps that can be shared with other blueGeiger users around the world.  Click HERE for some screenshots of the blueGeiger Android app in action.  

NEW blueGeiger now features Windows connectivity (XP onwards) using an inexpensive Bluetooth adaptor (not supplied). This will let you log and display readings, as a graph or table on a Microsoft Excel, spreadsheet. Full details and connection instructions supplied on request

Gamma Master II Geiger Counter Watch, £520.00 inc. UK courier delivery

This has to be the very last word in luxury personal radiation monitoring and precision timekeeping. It’s the remarkable Gamma Master II PM1208M radiation sensor watch, a unique combination of Swiss engineering and a sophisticated gamma dosimeter, professionally calibrated by renowned radioactivity measurement experts Polimaster.

So who would want such an unusual device? Well, it’s a very long list, and includes just about anyone who wants to be able to keep on eye on their exposure to natural and man-made ionising radiation and, more importantly, be alerted when it rises above normal background levels. It will also be of particular interest to those who may come into contact with radioactive materials and radiation, working in hospital X-Ray and radiological medicine departments, undergoing radiotherapy, emergency and security personnel, the military, first responders and not forgetting people employed in the nuclear industry. You can also add airline pilots and frequent flyers that are exposed to higher than normal levels of cosmic radiation. Then there are geologists, mineralogists, miners, antique dealers and collectors, watch repairers and so on… We could go on, but let’s take a closer look at what it does.

It tells the time, of course, and the Gamma Master II has two clock displays: an accurate Swiss made, quartz-controlled analogue movement with luminous sweep second hand, and a secondary LCD display, showing hours, minutes, seconds, day, month and year, plus it has a daily alarm function. An electroluminescent backlight panel illuminates the display so it can be read at night and the tough but stylish stainless steel case is water-resistant and rated for depths of up to 100 metres (328 feet). Now for the really interesting stuff.

This unique watch contains a gamma-sensitive Geiger Müller tube radiation detector and monitoring circuitry designed to measure Dose Equivalent Rate (DER) and Dose Equivalent (DE), with programmable alarms to alert the wearer if the levels exceed a preset threshold. Dose Equivalent is a measure of radiation absorption by biological tissue, and an indication of potential health effects. This is expressed in internationally recognised standard units known as Sieverts. DER is a measure of DE in relation to time and the display on the Gamma Master II is constantly updated and shown in microsieverts per hour (µSv/hr). In addition, the Gamma Master II has a DER recording facility and it can store up to 500 readings, along with time and date, which can be uploaded* to a Windows PC** and displayed, graphed and recorded, along with readings from other Gamma Masters, using supplied software. The Gamma Master II’s DE reading, in millisieverts (mSv) gives the wearer a long-term indication of dose accumulation (1 – 9999 hours) and again there is a threshold alarm that sounds an audible bleep if DE exceeds a preset threshold.

To round off the key features, Gamma Master II has analogue bargraph indicators showing approximate percentage of DE and DER in relation to thresholds, a low battery indicator, full function reset button, switchable alarm mute. It is fitted with a heavy-duty stainless steel clasp strap and it comes in its own heavily lacquered presentation case with instructions, CD-ROM and calibration certificate.

Voltcraft Gamma Check Geiger Counter,

£159.99 inc. UK p&p

And now for something a bit special! Presenting the Gamma Check, a compact hand-held professional ‘frisker’ style Geiger counter, featuring a bright backlit LCD display, simple to use controls and two operating modes. For rapid and direct measurement it has a discreet audible ‘ticker’ and can be set for constant monitoring, giving a simple and accurate cumulative indication of radioactivity, with a regularly updated readout showing average count (intervals of 30, 60, 90, 120, 150 or 180 seconds) and dose in µSv/h. Alternatively it can be set to Dose Meter mode, for investigative long-term dose measurement. Readings can be taken over periods of between 6 and 40 hours, in 6-hour steps, and it has an audible alarm that sounds when radiation exceeds a preset level (between 0.1 and 50µS/h in 59 steps).   

The super comfortable shape is designed for single-handed operation, with the large clear LCD display positioned for maximum legibility and the four multi-function control keys (On/Off/OK, menu, up/down) falling readily to hand.

It is small, measuring only 180 x 86 x 45mm, and with a all up weight of only 178 grams (including battery), so it is small enough to slip easily into your pocket. Power comes from a standard 9 volt PP3 type battery, which can last for many weeks, with normal intermittent use (depending on battery type, LCD brightness, ticker mode etc.).

By the way, you may also be interested to know that the display is switchable between count and bargraph, the LCD has variable contrast, the on-screen menu is in English or German, and there’s an auto-power off option, after 5 measuring cycles. Brand spanking new in its box, supplied with English and German instructions plus a free battery, so you can start gamma checking right away. 

NEW Air Geiger Counter Kit, £149.99 inc UK p&p -

LIMITED STOCKS

How does a Geiger Counter work? Well, now you can find out with this new and innovative DIY kit from Japan. It includes virtually everything you’ll need to build your very own highly sensitive, portable radiation detector, capable of registering Alpha, Beta and Gamma radiation, from normal background levels upwards; it will even detect the tiny amounts of radiation produced by ‘Low Salt’ reduced salt substitutes. As an added bonus it can be connected to a Windows PC for monitoring and long term logging.

What makes this kit really special (and a perfect teaching tool for anyone who wants to learn about the science behind radiation detection) is that you get to construct an actual Geiger Müller tube. That’s right: this kit includes all of the materials you’ll need to make the critical component used in the majority of commercial and industrial radioactivity monitoring instruments. (In fact you’ll have to provide a bits and pieces but they are all widely available and easily obtainable household items – see below). And if you want to see for yourself how easy it is to make, you can download the instructions (pdf format) by clicking HERE.

The only other things you’ll need are a few simple tools, a soldering iron, and the ability to use it.  If you have a Windows PC you can also monitor and record readings and make configuration changes using free software (see right). It’s actually very easy to build and should only take a few hours to put together, but please be aware that it is not for absolute beginners, or children – without adult supervision. If you’ve never done any soldering before you’re better off with one of our ready-made radiation monitors.

Now that we have your attention here are some key features.

It’s a fantastic little project for hobbyists, experimenters, schools and colleges but please be aware that we make no guarantees as to its accuracy. It is not designed for serious scientific measurement or for use in safety critical applications. This unit produces some very high voltages, they’re safely contained inside the case, but it is not suitable for those unfamiliar with electronic circuitry or children without adult supervision.

Here’s one we made earlier (see picture right).The silver tube on the left of the case is the homemade ‘Air’ Geiger Müller tube.

If you get into a tangle we should be able to help with advice – or point you in the right direction -- and we can supply most replacement parts, prices on application.

CDV-700 (6A/6B) Classic & Original Geiger Counter,

£195.00 inc UK p&p

This is a genuine piece of Cold War memorabilia, highly collectible and it works, too! The Victoreen CDV-700 was made for the United States Civil Defence corps throughout the 1960's and 70's. No expense was spared in their design and construction - they were built to survive a nuclear war, after all  - but they are very sensitive and will detect natural background radiation, as well as higher levels, up to and including lethal doses...

The device has a chrome-plated brass probe with a rotating ‘shield’ for discriminating between beta and gamma sources. It’s detachable and fits into the carry handle when not in use. The CDV700 has four ranges, covering 0 – 0.5, 0 – 5 and 0 – 50 mR/h (millirontgens per hour), with readings shown on the large meter. (They have not been calibrated for some time so we’re making no claims as to their accuracy). It is powered by 4 standard 1.5 volt D-Cells and with normal use will last several weeks or even months.

An original purpose-designed headphone will be included with the unit, to let you hear the characteristic ‘clicks’ when the probe is exposed to a radioactive source*.

The case is water resistant and made from tough cast alloy; the lower cover is held in place by two toggle clips. It weighs approximately 1.5kg (ex batteries) and measures 120 x 210 x 170mm.  They come with a copy of the instruction manual plus the original headphone and carry strap. * Check source labels are removed before export from the US : however we can supply an original inert/dummy label for an additional £3.50.

NEW Re-Metered CDV-700 Classic Geiger Counter,

£150.00 inc UK p&p

We have managed to secure a small stock of decommissioned Victoreen 6a/b CDV-700s that have had the meters removed. Unfortunately original meters are now rarer than hen’s teeth, so we’ve developed a modern replacement (soon to be released as a kit). Otherwise they are completely original and in full working order. For a more detailed description see below.

They are in generally very good condition, no rust or corrosion, though there may be a few dinks and scratches on the case, and some samples have been touched up with a slightly off-shade yellow but overall they look really good for their age.

As usual with instruments of this age we can offer no guarantees as to their accuracy, but they are very sensitive and capable of detecting natural background radiation (beta and gamma) and higher levels up to and including lethal doses.

Each unit comes with an original high-impedance headphone, a carry strap and a copy of the original instruction and maintenance manual.

Please note that there may some scratches on one side of the case where the check source label has clumsily been removed (not by us we hasten to add…)

K8 Nuke Safeguard Miniature Radiation Monitor,

£165.00 inc.UK p&p

It’s the K8 Nuke and no, your eyes are not deceiving you. This marvel of microchip engineering is a fully-fledged radiation monitor and it is really is no larger than an ordinary postage stamp. It’s almost certainly the world’s most sensitive miniature radiological warning device. But how can something that small be any good?

Well, the US California Highway Patrol (CHiPs), Colorado and New Mexico State Police, Las Vegas Fire and Rescue and thousands of safety professionals, law enforcement officers, security personnel and first responders certainly think it is.

Time to take a closer look. It has three bright LED indicators visible from the top and front. The green one flashes in the presence of radiation, typically once or twice a minute – depending where you are -- due to normal background radiation. The red LED flashes and an audible alarm sounds when the radiation level exceeds 5 mR/Hr (50uSv/h) or more. When the yellow LED flashes it’s time to change the battery, but that doesn’t happen very often as it’s capable of operating continuously for 1500 hours, that’s 60 days or more, on a standard CR2032 battery. On the back there’s a small on/off switch and a fiercely strong spring clip for attaching the monitor to your belt, pocket or lapel. It will not fall off!

This tiny device is designed and built in the US and it uses a solid state silicon-based detector that is sensitive to Gamma and X-Ray radiation in the range 30keV to 6.2Mev.

It’s a serious piece of kit, CE Approved, and it meets NCRP Guidance & Recommendations for Management of Terrorist Events. It also complies with EMC Directive Standards and is tested using NIST traceable sources. It’s tough too; the high impact housing exceeds ANSI 13.27 drop test requirements and it will happily operate between –20 degrees C and + 50 degrees C. If you are still wondering about the size, it measures just 25mm x 39mm x 12mm (1 x 1.5 x 0.475 inches), and tips the scales at only 13g or about 1/2oz and that’s small. The K8 comes with a battery already  fitted, so it's ready to go.

NEW Radex RD 1706 Geiger Counter with Russian menu display & English instruction manual, £280.00 inc UK p&p

GeigerActiv pro mk 2, personal radiation monitor,now £165.00 inc UK p&p

The  GeigerActiv pro mk 2, exclusive to anythingradioactive, is a compact, smart-looking hand-held radioactivity monitor that can alert you to normal and elevated levels of beta and gamma radiation (minimum sensitivity =0.35 Mev).

Features include:

• Extended  battery life giving between 200 and 400 hours of continuous operation from a single AAA cell
• Beta and Gamma sensitivity
• PC connectivity with free software
• New round meter showing relative cpm
• New belt clip
• New rear mounted sounder
• Audible power-on alert buzz
• New single-button operation
• Light and compact (about the size of a pack of cigarettes)

The presence of ionising radiation is indicated by a flashing red LED, an audible click from the built in piezo sounder and a clear visual indication on the front mounted moving coil meter. A second green LED remains continuously lit when the unit is switched on, to show that it is functioning.

It is a true Geiger Counter and by connecting it to a Windows PC (see note below) the free software, downloadable from our website, shows actual counts per minute (CPM) and total count. Furthermore this can be calibrated to display milliRontgens/hr (mR/hr). The results are also presented on a customisable real-time graph. Additionally the data can be stored to produce a detailed log, providing unlimited integration times, so you can measure very low levels of activity. The program also includes a web server, so results can be monitored remotely via a standard web browser. A PC connecting cable is supplied with the unit.

Designed and built in the UK, GeigerActiv pro measures just 60 x 30 x 105 mm (2.3 x 1.2 x 4.1 inches) and weighs just 91g (3.1 ounces) so it is just a little larger and not much heavier than a pack of cigarettes and slips easily into a coat or jacket pocket. There's just one control, a front-mounted power switch, so it is extremely easy to use and ideal for some discrete urban prospecting - granite kerbstones can be surprisingly 'lively' - checking antiques (old watches, clocks and instruments with radium dials, uranium doped ceramics and glass etc.), and keeping a check on your environment.

GeigerActiv pro SE (Solar Edition) now £185.00 inc UK p&p - complete with USB charger & 2 rechargeable batteries

It’s the World’s First Nuclear Powered Geiger Counter. That’s right, this specially developed variant of the GeigerActiv pro mk 2 (above) derives its power from the biggest nuclear reactor of them all, our Sun. Fitted to the rear of the case is a silicon solar panel that charges a NiMh (nickel metal hydride) AAA cell inside the case. Two are supplied with the unit, so it’s always ready for use. The solar cell will even power the GeigerActiv pro SE directly on a really sunny day. If it’s cloudy or you want to do a spot of night-time detecting you can pop in an ordinary non-rechargeable AAA cell. Either way you can expect it to run continuously for between 200 and 400 hours on a fresh battery (depending on the type/state of charge). The outfit also comes with a USB charger, so the cells can be recharged from your PC or a suitable mains adaptor (not supplied). General specification and features are similar to the standard GeigerActiv pro.

GeigerActiv Personal Plus 2, Pocket Monitor and Geiger Counter

The GeigerActiv Personal Plus2 pocket radiation monitor is a dual-mode device, operating independently as a fully self-contained pocket dosimeter, but connect it to a PC and it becomes a versatile Geiger Counter, able to constantly monitor and log radiation levels – but more on that in a moment.

Key Features

• Beta and Gamma sensitivity  (≥0.35 Mev)
• Power on and activity detect LEDs
• Discrete built-in Piezo sounder
• Long battery life (200 – 500 hours continuous)
• Single AAA battery operation
• Simple single button on/off control
• 3.5mm jack socket PC connection
• PC connecting cable supplied
• Small size (55 x 80 x 25mm)
• Light weight (58g inc battery)
• Belt clip

GeigerActiv Personal Plus2 has just two indicators, a yellow power on LED and when it detects radioactivity it flashes a red LED and generates a discrete audible click from the built in, front-mounted piezo sounder. It is sensitive enough to respond to normal background levels and in most parts of the UK it will flash and click between 2 and 10 times a minute. As the level of radioactivity increases, or you bring the unit closer to a source of radioactivity the clicking and flashing gets faster. This makes it ideal for some urban prospecting, checking mineral samples and so on, you can even get a reaction from some granite kerbstones. It’s a boon for antique collectors too and items made from uranium-doped Vaseline glass, clocks, watches, compasses and instruments with Radium painted dials, old gas mantles can all produce a lively reaction.

This model is powered by a single AAA cell and it can be expected to run continuously for between 200 and 500 hours or more – that’s three weeks -- depending on the battery type and ambient conditions. With intermittent use it will operate for many months before the battery needs replacing.

With the free software that you can download from our website the GeigerActiv Personal Plus2 become a fully-fledged Geiger Counter, displaying the results on your PC or laptop screen. The counting and data logging program shows actual counts per minute (CPM), total count, and this can be calibrated to display milliRontgens/hr (mR/hr). The results are also presented on a customisable real-time graph. Additionally the data can be stored to produce a detailed log, providing unlimited integration times, so you can measure very low levels of activity. The program also includes a web server, so results can be monitored remotely via a standard web browser. Supplied with simple to follow instructions and a PC connecting lead.

CDV-715 Survey Meter, £50.00 inc UK p&p

Produced in the 1960s and not to be confused with a Geiger Counter (as recently seen on Amazon) the CDV715 Survey Meters were produced during the Cold War for the US Civil Defense Corps but were never issued and have remained in storage until recently. They are in fair condition and come with a copy of the instruction and maintenance manual and shoulder strap.

These units are believed to be in good working order, but we have to say straight away that if you ever see the meter on one of these instruments move, you have probably just survived a nuclear explosion!

The 715 was designed for a post attack situation and only responds to dangerously high levels of radioactivity (scales read from 0.5 – 500 Roentgens/hr), to let survivors know it was (relatively) safe to emerge from their fallout shelters.

Nevertheless, experimenters may be interested to know that it is technically possible to modify these units to increase their sensitivity at least tenfold so that they will respond to much lower levels of radioactivity. However, this requires a fair amount of expertise in electronics and soldering skills and access to some specialised components. A link to instructions on how to modify these units will be provided to purchasers on request. 

These instruments use an Ion Chamber detector module and are powered by a single ‘D’ cell. It has two controls, a rotary switch for circuit/battery test, meter zero and range selection, and a rotary control for meter zero adjustment. The all-metal case is water resistant and the standard of construciton, and materials used are of the highest standard – as befits a product built on a cost no object government contract. It might not do much, but it’s a real conversation piece, and who knows, one day it may come in useful…

CDV-750 Charger & CDV- 742 Dosimeter, 

£27.00 inc UK p&p

The CDV-750 charger is powered by a single ‘D’ Cell, which lasts for months. It was made in the 1960s for the US Civil Defense Corps and was built to last – to survive a nuclear war in fact. It's been in storage for the past 40-plus years, so there’s some small signs of wear as they’ve been periodically taken out and tested.

This is designed to be used with the CDV-742 pen dosimeter (see photo).

The CDV-750 comes with the CDV-742 Pen Dosimeter and a copy of the original instructions; and yes, as far as we can tell it still works. The CDV-742 can be charged and the reading on the scale can be zeroed, but in the absence of highly radioactive fallout we haven’t been able to fully test them. 

GeigerActiv K Personal key fob radiation monitor,

£90.00 inc UK p&p

Back for a limited period

GeigerAcitiv K is one of the smallest – if not the smallest – Geiger Tube radiation monitors currently available. As you can see it is no larger than a car alarm key fob and fits happily onto your keying, or you can wear it around your neck using the supplied yellow lanyard.

GeigerActiv K is capable of providing continuous around the clock monitoring, and the supplied 1.5-volt battery keeps it running for more than 200 hours; it will last for many months if used intermittently. GeigerActiv K responds to both normal background and elevated levels of Beta and Gamma radiation (sensitivity ≥0.35 Mev) indicating the presence of activity by flashing a red LED and emitting a characteristic discreet ‘tick’ from the built in piezo sounder; the green LED remains continuously lit to show that it is operating. Depending on you location normal background radiation will make it tick between 2 and 20 times a minute.

It is very small and unobtrusive and ideal for keeping a constant check on your environment; it’s also very handy for checking potentially radioactive items, such as uranium-doped antique glass and porcelain, old clocks, watches and scientific instruments with luminous radium-painted hands and dials, suspect scrap metal objects and so on.

GeigerActiv K measures just 60 x 35 x 15mm and weighs (ex battery) only 25g; it is supplied with a neck lanyard with detachable clip, one LR1 1.5 volt battery and instruction manual.

About the CDV-700

The CDV-700 is a true Geiger Counter, displaying an accurate count (when properly calibrated) of beta and gamma jsources. This particular model was manufactured for the Civil Defense Corps by serveral companies in the US, including ENI, Victoreen and Lionel Electronic Laboratories (who also made toy trains). They were produced in fairly large numbers throughout the 1960s and 70s in preperation for expected nuclear conflict.

These devices are based around a 6993 Geiger Muller tube, driven by a simple high voltage circuit producing around 1000 volts. The output from the tube is processed by a transistorised pulse shaping network and integrating circuit, to operate the moving coil meter; a simple audio amplifier drives the supplied headphone.  Many different types of geiger counter were produced during this period but the CDV-700 6b is one of the most popular due to its high sensitivity, rugged construction and legendary reliability.
