NEW Radex RD1503 Geiger Counter Outfit, £99.50 inc. UK P&P

LOW STOCKS - MORE EXPECTED SOON

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.

CDV-700 6b Civil Defence Geiger Counter, £83.99 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.

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

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 may have slight scuff marks or chips. 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.

BIRI-1 Key Ring Geiger Counter/Dosimeter £54.99 inc. UK P&P

Here’s something really different and very special. It’s a tiny Russian Geiger Counter that fits on a key ring. It’s a brilliant design, very sensitive and it responds to background and elevated levels of ionising radiation (beta and gamma). In normal use it ‘ticks’ quietly a couple of times each second, to let you know that it is working and all is well, but as soon as it detects any radioactivity the red LED on the top flashes and it emits a warning bleep.

A simple colour-coded scale on the rear indicates the relative danger level. Green or fewer than 12 bleeps per minute (bpm) is safe and represents normal background levels. Yellow or between 12 and 24 bpm and this indicates caution. Red is for 24 to 60 bpm and warns of a potential hazard and any more means danger, get out of there!

These ingenious little devices are relics of the post Chernobyl era and are no longer being made. They are now in extremely short supply and when they have gone there will be no more! The few units we have for sale were made over 10 years ago but they have been kept in storage and have never been used so they are in as-new condition and fully working. In fact the only signs of aging are the very slightly tatty cardboard storage boxes, otherwise they look as though they have just come out of the factory.

They are powered by two small button cells and they come with a pair of new re-chargeable cells and a mains charger. These cells will keep the BIRI-1 running continuously for 50 hours or more between charges.

However, in our opinion the charger units are a little crude. Whilst not electrically unsafe, they are fitted with an integral continental 2-pin plug, which will fit into a 2-pin shaver socket but requires an adaptor to be used on a standard 3-pin UK mains socket. Nevertheless, we advise against the use of the charger facility and suggest instead that you use readily available single-use button cell. Two will be supplied with each unit. On average these will run the unit non-stop for 4 - 5 days, or several weeks or even months with intermittent use. We can supply larger quantities of these cells at competitive prices if required. Dimensions 70 x 40 x 18mm. Weight (ex batteries) 50g.

DRGB-90 Geiger Counter £59.99 inc. UK P&P

This is an advanced pocket Geiger Counter/Dosimeter with both visual and audible alerts, plus a meter readout showing accumulated exposure to beta and gamma radiation in both microsieverts per hour (uSv/h) and microroentgens/hr (uR/h).

The device has two operating ranges of 0-3 uR/h and 0-30 uR/h, selected by the x1 and x10 switch. The meter scales are colour coded with green representing normal background levels of radiation; yellow  indicating elevated levels and red indicating potentially harmful levels.  Measurements are made continuously and the integrated dose rate will be displayed after approximately 60 seconds. Other controls include switches for a meter backlight, audible indicator mute and ‘Dump’ which resets the meter. The unit has a built-in battery check and it is powered by three AA cells, which will give approximately 300 hours of continuous operation. The case measures approximately 70 x 30 x 140mm.

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. 

About the DSRB88

The DSRB-88 is really small, not much larger than a pocket pager. There's a belt/pocket clip on the back and it is powered by a single AA cell that lasts for ages --  it will run for a week or more on an alkaline battery. It's really simple to use, the only control is an on/off switch on the front. On the top there's a bright red indicator lamp and a tiny speaker that emits a 'click' when the dosimeter detects radioactivity. All of the panel markings are in Russian but it comes with a set of English operating instructions. 

It is very sensitive and reacts to natural and background radiation on average emitting around 20 to 30 clicks per minute.

It's not a serious scientific instrument or safety device. Nevertheless, it is a great little gadget, a real conversation piece and it will alert you to the presence of normal and dangerous levels of radioactivity. Use it to monitor your environment, your food and anything or anyone you come into contact with.  

About Geiger Counters

The DSRB-88 and BIRI-1‘dosimeters’ are designed to detect the presence of ionising radiation. The actual detector is a small device called a Geiger Muller tube. A high voltage (400 to 1000 volts) is applied to the tube; inside there is a mixture of gasses ,which react to the presence of radioactive particles, generating a brief ‘pulse’. An electronic circuit amplifies the pulse  - producing the characteristic ‘click’ or 'bleep' -and making the indicator flash.
