Temperature calibration of Pico-Rad detectors for radon measurement.

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… CONTINUE READING
