Riso GM-25-5A Low-level beta GM multicounter
Brand: Riso | Category: Scientific & Laboratory Equipment
A low level gas flow Geiger Muller multicounter that measures five samples at the same time. A common guard counter cuts the cosmic ray background by anticoincidence, and the unit is normally placed inside a 100 mm lead shield for environmental radioactivity work.
