Tools and Hardware Reviews of Low Cost Geiger Counter
Customer Review: radioactivity counter- low cost geiger counter
Summary: 4 Stars
I bought this device to use as the subject of a hiking project with my grandchildren, mapping with a GPS as I go and recording the local radioactivity as I go. (It should make a nice intellectual point to hiking.)
I first tried the device at my home (unradioactive I hoped) and then some other places that I knew, from previous use of laboratory-grade counters, definitely had some local radioactivity in the sand and cliffs and it gave readings more or less as I expected from the previous use of much more expensive counters. As another test, it also picked up radioactive gas-mantles quite well indeed when I sat the device upon one (the luminescent gas-mantles as often used in camper lamps are often very solidly radioactive--- a ref on this is available if amazon requests) The strong signal was expected but it was reassuring to get it. The device is convenient to use and I found gave repeatable results although you have to leave it sit for a few minutes to get a reliable result. Note that if you use gas old-style mantles to test it yourself please make sure they are the old-fashioned thorium based gas mantles as the many modern gas mantles are no longer radioactive. In my experience the non-radioactive mantles advertise this clearly on their packet and the old radioactive mantles are discreetly silent about radioactivity on their packet. (Choose one from an old camping shop that doesnt mention radioactivity on its packet and then dont sleep near it!)
The four stars come from its very low price for doing an adequate job.
Description of Low Cost Geiger Counter
Excellent geiger counter for the money!Designed for evaluation of ambient dosage of gamma radiation, which can be done by ordinary people in domestic environment (homes, office, food products, construction materials, soil, etc.). Also, the instrument can be used by industrial personnel, working with ionizing sources of radiation. Moreover, the instrument can detect objects, polluted by beta active radioactive nuclides.
The instrument uses a Geiger counter to detect the amount of gamma radiation within 40 sec. and indicates the values in ?Sv/h and ?Rem/h on an LCD screen. Registration of every particle is indicated by a click sound, which makes it possible to quickly determine the location of hot spots.
Incorporates the following features: audio alarm with 3 adjustable thresholds, continuous updating of readout in proportion as duration of measurement increases, display illumination, MENU in English. CE. 3 year factory wty. Radex Model RD1503.
