WebConverting From CPM to mR/hr Many radiation survey meters are calibrated to Cs137 or Co60. For Co60, it turns out that the conversion factor for the GM-10 to convert CPM to uR/hr is very close to 1 (0.93, but 1 is close enough for most purposes). This means that 1080 CPM is about equal to 1 mR/hr for Co60. WebApr 16, 2012 · For example relatively modest thicknesses of lead are able noticeably to reduce the background dose rate to a detector.
