A Comparison of Methods For Prompt Determination of Potential Alpha Energy Concentrations

The object of this study was to verify experimentally an optimisation procedure used to reduce the total time needed to obtain an accurate estimate of potential alpha energy concentration (PAEC) of 222Rn Progeny for a grab sampling method with only one count of gross alpha activity. Samples of air w...

Description
Summary:The object of this study was to verify experimentally an optimisation procedure used to reduce the total time needed to obtain an accurate estimate of potential alpha energy concentration (PAEC) of 222Rn Progeny for a grab sampling method with only one count of gross alpha activity. Samples of air were analysed for potential alpha energy at concentrations near 2.08 X 10-6J.m-3(0.10 WL) using timing intervals of 7, 13, and 25 min. The measurements were compared graphically and statistically to estimates of PAEC obtained using the modified Tsivoglou method. No statistical difference in accuracy were found within or between the three total timing intervals. Suggestions for practical field instrumentation are presented.
