The results would be recorded in counts per minute (cpm) . When recording information on a survey we have already subtracted the background and are recording the results of levels found.

Our procedure currently says to record the measurements in disintegrations per minute (dpm). How does your plant document fixed/total contamination measurements by direct frisk on surveys? ncpm? or dpm? We noted that unfortunately this issue was not addressed in the INPO RP standard PP-06-01, Survey Map Conventions. Thanks, Eric Eric M.
