Abstract

A commercially available activated charcoal detector for measuring Rn-222 activity concentrations in air was calibrated with known amounts of Rn-222 and examined in terms of air luminescence counts and interferences from Rn-220 and Rn-219. The results for conditions normally encountered indoor indicate that the detector is simple and reliable. The method has been applied to assay indoor Rn-222 activity concentrations in 387 homes in Tokyo and the adjacent four prefectures, which ranged from 0.7 to 140 Bq/m(3) and averaged 22.7 Bq/m(3).
