Calibration procedures and protocols for radiation sampling pumps and alpha-particle scalers.

摘要

Results of flowrate calibrations of radiation sampling pumps as well as efficiency calibrations of alpha-particle scalers have been compiled and analyzed for the past three to four years. Careful analysis of data shows no real deterioration of the pumps or any other time-related trends. There does appear, however, to be a high degree of variability from one pump calibration to the next. For this reason a calibration result analysis, that will help remove some of the uncertainties associated with pump calibrations, is suggested. Some comments are also given concerning alpha-scaler efficiency that supports frequent calibration and close scrutiny of these results. (Atomindex citation 21:018655)
