Abstract:
A simple mathematical equation linking the activity of adsorbed radon in the vials to the time and temperature of its exposure is discussed. The calibration coefficient--Ks, defined as activity measured in cpm after saturation time, corresponding to radon air concentration of 1 Bq m-3, was determined for four temperatures: 284, 291, 294 and 298 K. A linear relationship of ln Ks values versus T-1 was found. The relatively high difference in Ks values: 2.12 and 1.24 cpm/Bq m-3 for the temperatures of 284 and 298 K, respectively, was observed. It indicates that temperature fluctuations during Pico-Rad vial exposure may lead to erroneous results if the constant average temperature of exposure is introduced into a commonly used computer programme for calculating Rn concentration.
