A complete detector assembly utilizing a 25mm diameter end windowed GM tube for Alpha Beta Gamma detection. The plastic stand includes a sample tray and features 10-slots with 1cm spacing for performing inverse square law experiments and holding radiation absorbers.
The GM probe is readily removed from the stand for safe storage, hand-held applications or replacement.
Component Parts.
Replacement GM tube. 25mm end window, 2mg/cm2, 150v plateau, 150 microsec. deadtime, BNC connector. 25mm OD, x90mm L.
Similar to the GP 25 but with a 35mm Geiger tube for added sensitivity and improved counting efficiency.
