Lightweight, great, battery efficient portable classic style geiger counter that can measure contamination on people's shoes, hair, workbenches.
Quickly and reliably detects alpha, beta and gamma radiation and has a table on the back to correlate the counts/second readings to gamma dose rate or becquerels/square centimetre of strontium-90 and other contaminants (the type of radiation is easily discriminated by using a piece of paper to stop alpha rays, 5mm of aluminium or perspex to stop most beta rays, etc.). Lightweight (just under 1 kg including PP9 battery and probe). Has a high radiation warning alarm bleep, plus space in the battery compartment for a small radioactive check source like a uraninite or pitchblende sample or an old thorium-232 gas mantle or the Amersham International Type 1623 3-microcurie natural uranium metal disc (22mm diameter, 1mm thick, 111 kBq beta activity) beta source with a screw-up aluminium pocket sized storage container that stops all of the radiation, if you were lucky enough to buy one in the 1980s before natural uranium metal sales to the public were banned. Photo shows the response of the meter to beta from the uranium disc, and a Thermo RadEye SX with huge DP6 alpha-beta dual probe (vacuum cleaner shaped) is included for scale.
