Ludlum Model 44-9 with "C" Connection - Like new conditionThe Ludlum Model 44 9 is a "Pancake" style GM Detector. This detector is sensitive to alpha, beta, and gamma radiation. Its size and shape provide easy handling for surveying or personnel monitoring. The detector is energy dependent, over responding by a factor of 6 in the 60 keV to 100 kdV range when normalized to 137Cs. Application: Alpha, Beta, Gamma Survey, Sample Counting Detector: GM Pancake Active Open Area (cm2): 15 12, Window (mg cm2): 1. 7

One hot and four advanced buttons – easy to use Alarm relay output – for area monitor application
