Cylindrical Pancake G-M Probe
“ Great for floor surveys!”
This  probe is used for alpah-beta-gamma detection. It has 12 cm2 open area with typical efficiency of 5% for C-14, 22% for Sr-90/Y-90 and 15% Pu-239. Gamma sensitivity is 3300 cpm/mR/hr for Cs-137 (same GM Detector as the 44-9). Different construction allows for better frisking and floor survey. Interchangeable with any other GM probe.
