This is a pocket size Radiation Alarm and Geiger Counter. It has two operating modes: Alarm Mode and Geiger Counter Mode: In Alarm Mode it sits quietly on a tabletop or in a drawer and does nothing (like a smoke detector) until radiation levels become dangerous in or near your home. If there is a radiation increase, as from a dirty bomb or a nuclear bomb, a beeping alarm will sound. This device can save your life if radiation is a problem near you. The internal sensor is directional and can pinpoint radioactive sources. If there was a radiation release near you, you would know where it would be safe to stand, or if radioactive dust had settled on your shoes or shirt, or on your car, etc. Unlike most radiation alarms, this device reacts instantly to radiation level changes (other devices require minutes or longer and make it difficult to pinpoint radioactive sources). In Geiger Counter Mode the internal speaker produces “ticks” just like a classic Geiger Counter. The unit is easily sensitive enough to measure background radiation and can measure radioactive sources such as active rocks, watch dials, radioactive marbles and pottery, and radioactive smoke alarm elements. Walk it around your back yard and see if anything is radioactive. The unit interfaces to any PC computer to become an accurate laboratory-grade measuring device. A MSDOS software program is included that lets you accurately plot radiation levels in a bargraph form on your computer screen. The software program lets you set various sensitivity levels and time durations for plotting.

Plessey PDRM 82 Radiation Geiger Counter Meter

Here we have a new, Plessey radiation meter, supplied in white cardboard box of issue. These were standard issue to all Royal Observer Corps members, and also troops involved in detecting the presence of nuclear fall-out and bomb-blast. They were also supplied to Civil Defence organisations in the UK. Comes complete with shoulder strap and neck lanyard, along with full instructions. These meters use a small radiation source of Caesium 137 with an intensity of 13 becquerels. This source has a half-life of 30 years, decaying to Barium, so you can see that this item now has close to half its original source left. For this reason, the item cannot be guaranteed to work accurately, even though it is new and unused. Nice compact item, the perfect addition to any cold war memorabilia collection.

The PM1603A/PM1603B dosimeters are the only dosimeters in the world designed for automatic control of radiation situation and dose accounting. They are designed for measuring the ambient dose equivalent (DE) H*(10) and ambient dose equivalent rate (DER) H*(10) of gamma radiation within the background values up to 5-10Sv/h in a wide energy range. The dosimeters have two alarm thresholds and in case the preset values of dose and dose rate are exceeded the dosimeter immediately alerts the user of a danger to be irradiated. In cases when the radiation intensity exceeds the upper limit of the dose rate measurement, the LCD of the dosimeter shows the warning sign “OL” followed by the interrupted audible signal. The dosimeter is capable to store up to 1000 histories of dose rate measurements, accumulated dose values and its own factory number in its non-volatile memory. These data can be transmitted from the dosimeter to a PC through the standard communication devices IRDA type for further procession and analysis and for presentation of this information as correspondent data bases or as graphs. Shockproof hermetic case protects the electronics of the dosimeter from mechanical impacts. The dosimeter is ideally suited in extreme climates and harsh environments, it meets the requirements of drop tests which are 0.7m height to a concrete surface. The electroluminescent backlight of the LCD makes it possible to use the dosimeter in the dark. The efficient power supply enables the user to measure the accumulated dose up to 10Sv/h using one battery which discharge is automatically controlled.
FAG-SV500 Geiger counter/Dosimeter/Radiation Detector

Manufactured by Frieseke & Hoepfner (Erlangen, Germany) since the 1980´s, the SV500 was the “gold-standard” in the german army for more than 2 decades. Since it´s successor – the IM7001, becomes to be produced, ever more SV500´s sporadically find their way out of the army-barracks and inspire a wide range of users: geologists, radiation protection specialists or simply the hobby scientist, who searches a simple-to-use, professional dose rate meter.
The instrument comes in nice, splash-water protecting leather bag (which has practical holding-eyes for fastening a shoulder-band), together with all it´s accessoires:
– the SV500 basic equipment with the black high-dose gamma probe inside (which can also be used as an external probe and which allows measuring of dose rates even until deadly ranges of 1000 rad/h (approx. 1000 R/h)
– a external beta/gamma low/high-dose probe, which can measure combined beta/gamma – or just gamma radiation by easily turning the shielding around the probe
– the probe-connection cable to connect both the gamma and the beta/gamma-probe with the SV500
– a adaptor cable to supply your SV500 with energy over the cigarette lighter of your car (in case of empty batteries)
– a little speaker, with which you can make your readings also acoustically noticable
– a probe-wedge for fastening one of the probes onto a “walking stick”, long pipe, broom etc.
The self-explaining SV500 has six different, switchable ranges, which take off all (live)important ranges:
0 – 5 mrad/h (mrad/h = approx. mR/h), or 0 – 2,000 cpm (2 kcpm)
0 – 50 mrad/h, or 0 – 20,000 cpm (20 kcpm)
0 – 500 mrad/h
0 – 5 rad/h
0 – 50 rad/h
0 – 1000 rad/h
The first range is so sensitive, that you´re even be able to detect the normal background-radiation of approx. 20 cpm !!

This instrument is a dosimeter that gauges the dangerous kinds of radiation: beta, gamma, röntgen radiation and fast neutrons. It signals with a beeper when 0,5 Röntgen of received radioactive radiation (of all kinds) has been exceeded. The beeper can be reset with a switch on the side of the dosimeter. Because 0.5 Röntgen is a relatively low and a not really dangerous amount of radioactive radiation for humans this alarm dosimeter will excellently serve as a personal early warning system for radioactive radiation. The housing has been made of red/brown bakelite; inside are a Geiger-Müller tube, a lot of electronic components and a beeper. It is 12 centimeters (almost 5 inches) high so it is small enough to fit in your pocket. It has been manufactured by Total between 1960 and 1975 most likely in the USA. On the aluminum sheet sticker has been printed a.o.: AUTOMATIC ALARM DOSIMETER 0,5 R. – MONITOR PTW – TOTAL 6119 NO. 7052

Radiological Dosimeters CD V-742 by The LANDSVERK ELECTROMETER CO

For more than a quarter of a century, Dosimeter has been a leader in the development, manufacture and distribution of radiation detection equipment. THESE ARE PERSONAL UNITS made to carry in your pocket to determine when maximum exposure has been reached. A radiation dosimeter is a pen-like device that measures the cumulative dose of radiation received by the device. It is usually clipped to one’s clothing to measure one’s actual exposure to radiation. Magnifying lenses (a low-power microscope) and an illumination lens allow one to directly read the dose by aiming the illumination lens at a light source and looking into the device. For personal use, this is the most useful device to measure radiation, because biological damage from radiation is cumulative.

Rare Set of Yugoslavian/Serb Army Issue Dosimeter Set and Carrying Box. This set consists of 12 dosimeters and one dosimeter reader housed in a waterproof plastic carrying box with an attached shoulder strap. The dosimeters are designed to be clipped onto clothing and equipment. They contain a glass vial with a “liquid” inside. This I think changes colour when exposted to radiation. The colour of the vial depends on the amount of radiation exposed to. Each of the dosimeters has a differnet number on the top representing the dosage of radiation each dosimeter is designed to absorb. The dosimeter reader is made from plastic and comes in a telescopic three pieces. The dosimeter is uncapped and inserted in one end of the reader – the user then looks through the other end and turns a dail until a matching colour is reached. He then reads the radiation dosage on a top dial to see how much the wearer has been exposed to! Compared to UK and NATO dosimeters it is a strange method of measuring radiation! There are instructions included but these are printed in Serbian, however there are pictures and these tell a thousand stories!!
