Abstract
The object of this study was to verify experimentally an optimisation procedure used to reduce the total time needed to obtain an accurate e stimate of potential alpha energy concentration (PAEC) of Rn-222 proge ny for a grab sampling method with only one count of gross alpha activ ity. Samples of air were analysed for potential alpha energy at concen trations near 2.08 x 10(-6) J.m-3 (0.10 WL) using timing intervals of 7, 13, and 25 min. The measurements were compared graphically and stat istically to estimates of PAEC obtained using the modified Tsivoglou m ethod. No statistical differences in accuracy were found within or bet ween the three total timing intervals. Suggestions for practical field instrumentation are presented.
