NEW NEW NEW!

GeigerActiv PERSONAL and PERSONAL PLUS, Pocket Radiation Monitors and Geiger Counters, £49.00 and £55.00 inc UK P&P

Introducing GeigerActiv Personal and the latest addition to our range, Personal Plus; two new, innovative, low-cost, dual-mode radiation monitors and Geiger Counters, designed and built in the UK exclusively for anythingradioactive.com.

Geiger Active Personal and Personal Plus (Move your mouse over the picture for a close up) work in two ways, firstly as a portable, self-contained personal radiation monitor and when connected to a PC they become fully functional Geiger Counters. They slip unobtrusively into your pocket so you can keep a continuous check on your environment.

GeigerActive Personal and Personal Plus react to normal background levels of ionising radiation (beta and gamma, minimum sensitivity ≥0.35 Mev) by flashing a red LED indicator and generating a distinctive click from the built-in piezo sounder on the rear. Depending where you are this can be between 2 and 20 times a minute. If the background level of radioactivity increases, or you bring the unit closer to a source of radioactivity the clicking and flashing gets faster. This makes them ideal for checking mineral samples and antiques, such as items made from uranium-doped Vaseline glass, clocks, watches, compasses and instruments with Radium painted dials, old gas mantles and so on.

GeigerActiv Personal is powered by two standard AA batteries (alkaline cells are recommended) and these can be expected to last for between 12 and 24 hours with continuous use, very much longer with intermittent operation. The Personal Plus model runs from a single AA battery and this lasts between 50 and 100 hours, depending on the ambient temperature etc., so it is better suited to longer-term monitoring. Additionally, Personal Plus has a power on LED that remains on continuously, to let you know that it is operating.

Using free FREE software that you can download from our web site GeigerActiv Personal and Personal Plus become fully fledged Geiger Counters, 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.

Both models measure 138 x 40 x 26 mm and weigh approximately 90g (ex batteries) and come with a PC connecting lead and instruction booklet with information about the software download.

Radex RD1503 Geiger Counter Outfit, £149.99 inc. UK P&P.

*Guaranteed next UK working day delivery if ordered by 4pm*

This is the most sophisticated personal geiger counter/radiation monitor in our current range. It 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.

For a limited period we will also include a carry case* and you’ll also get one of our Radioactive Category I warning stickers. For display only.   The carry case design may vary from that shown   Order online or click Here to order by post.

CDV-700 6B Civil Defence Geiger Counter, £94.00 inc. UK P&P

A+ Condition, now with original headphone & maintenance manual

This is a genuine piece of Cold War memorabilia, highly collectible and it works, too! The CDV-700 6B was made by  ENI (Electro Neutronics Inc.) of Oakland, California for the United States  Civil Defence corps throughout the 1960s. and 70s. These sturdily built instruments have recently been removed from storage and are in excellent condition. 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)

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. It is powered by four  standard  ‘D’ type torch batteries, which last for approximately 100 hours in normal use.

These instruments have never been issued for use – they are ‘NOS’ or new  old stock – and have been in storage for a long time but they are in outstanding condition and look like new . Each one comes  in its original storage box  and will be supplied with a headphone, carry strap and its  operating and maintenance manual. See below for details of our cheaper Grade II models.

Grade II CDV-700 6 A & B Geiger Counter, £65.00 inc. UK P&P

                 OUT OF STOCK

We have acquired a very small quantity of Victoreen CDV-700 6A and 6B Civil Defence Geiger counters. These look the same and have an almost identical specification to the ENI models (above) but they are unboxed and the cases are scuffed (with some paint chipping) and show signs of wear. Otherwise they are in good working order, though they haven't been calibrated for some time, so we cannot guarantee their accuracy. These units come with a copy of the instruction and maintenance manual and stereo headphones.

CDV-700 Dual Probe Outfit, Alpha, Beta & Gamma £145, inc UK P&P

TEMPORARILY OUT OF STOCK

Our rugged and versatile CDV-700 Civil Defence Geiger Counter gets a major performance boost with the addition of a custom built Pancake Probe. This highly efficient probe is cable of detecting Alpha, Beta and Gamma radiation. The specially modified units are fitted with a connector allowing them to take both the standard Geiger Mueller (GM) ‘hotdog’ probe and the new 46mm mica-windowed model, housed inside a tough die-cast alloy case, with the distinctive ‘Civil Defense’ markings. Pass your mouse over the picture for a close-up

The new probe is between 10 and 20 times more sensitive than the standard GM detector and able to register very low-level sources. Try it on some ‘Low Salt’ salt substitute – yes, the stuff you put on your chips -- the Potassium Chloride it contains is surprising lively… You will be amazed at how much radioactivity there is out there, everything from granite kerbstones and counter tops, to smoke detectors and even the lint fluff from washer-dryers.

In addition to the Pancake Probe and modified CDV-700 (Grade II Victoreen model – see above for more information) you will also receive a probe connecting cable, the standard 'Hot Dog' GM probe with modified cable, headphones and a copy of the instruction manual.

The probe and cable is also available separately to experimenters able to fit their own connectors for £70.00, including UK p&p.(EU: £79.99, US: £84.99 - please email to order). We can also supply a modified Grade 1 ENI CDV-700s with a Pancake probe on special order for £170, including UK p&p. Email for details and options.

All units are now fitted with a 3.5mm jack socket and come with FREE stereo headphones. Optional speaker module module now available: see below.  If you prefer to keep your CDV-700 in its original condition let us know when ordering.   To hear it in action click    Please note this item is sent via Royal Mail Standard Parcel Service to the UK, which takes  between 3-5 days. We can also send it via a 2 day courier service for  an additional £10.

NEW CDV-700 Speaker (CDS001) £8.00 inc. UK p&p

Introducing our new amplified loudspeaker module for CDV-700 series Civil Defence Geiger counters. This self-contained unit has been designed to match CDV-700s and it produces a good ‘tick’ from the unit’s audio output. It connects directly to a 3.5mm jack socket, which is fitted upon request to all Grade 1 and II CDV-700s sold by us. Alternatively we can supply a special adaptor lead fitted with a CDV-700 headphone connector for an additional £12.00 (These connectors are no longer made and are now extremely hard to come by). We can also retrofit CDV-700s with 3.5mm jack sockets, please email for details.

The speaker is powered by a pair of AAA cells and these last for many weeks, depending on use. No fitting is required as the module is held in place on the CDV-700’s case by a pair of magnetic strips. For later models with alloy cases we supply an extra pair of self-adhesive magnetic strips. The module also comes with a 3.5mm jack adaptor lead.

Please note, the speaker module has been fitted with a simple filter circuit to suppress the annoying high-pitched whine present on the audio output of CDV-700s made by ENI, however, this may still be audible in the background but it is a very low level and should hardly be noticeable in normal use.

NEW CD-715 Survey Meter, £35.00 inc UK p&p

SOLD OUT

We have managed to secure a very small quantity of ‘New Old Stock’ CD-715 (model 1a) Survey Meters, made in the 1960s by Landers Frary & Clark. These were produced during the Cold War for the US Civil Defense Corps, but were never issued - they have remained in storage until recently. They are in as new condition and supplied in their original storage boxes, complete with the original 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. In other words they are not capable of detecting natural or even slightly elevated levels of radiation so they are being sold for their novelty value only.

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 construction, 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…

Some satisfied customers:

My order of the DSRB-01 unit arrived yesterday. I am quite happy about it. Everything works fine. Thank you for fast delivery. I will have a look at your offerings in the future.

Ulrich, Germany

The BIRI Geiger is amazing - I was really sceptical about how well something that small could work, but it's proven itself to be very effective. It's also a brilliant piece of history to own.

Matthew, Brighton

Thank you so much for everything, I'll recommend your web site.

JD, France

The Geiger counter has arrived in perfect condition and it is working. 40 years in the shelf, add some batteries and it works.... amazing!

CM, Germany

Thanks for the Pancake ENi Survey meter; it's working fine and it's great. Very pleased with it.

JP Chester

I would like to say a big thank you for the customer service that I have received. The package arrived quickly, and the after sale service has been excellent.  I would recommend anythingradioactive to my friends.

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.
