Detection instrument for observing scintillations produced by radioactive decay. When a radiation cartridge (226Ra, 4 kBq, U8483115) is screwed into the instrument so that its radiation outlet is directed downwards onto the exposed zinc sulphide screen, it is possible to look through the eyepiece of the instrument in total darkness and observe the random light flashes that are caused by radioactive decay.
Screen: 15 x 15 mm²
Please note: The required radiation cartridge is available separately and must be ordered additionally.
