Measurement of radon concentration in dwellings of Skardu city, Pakistan

摘要

Radon concentrations were measured in some dwellings of Skardu city, Northern Pakistan. The measurements were based upon passive detection of radon using CN-85 etched track detectors in box-type dosimeters. After 60 days exposure of detectors to radon in the dwellings, the track densities in the etched detectors due to the emitted alpha particles from radon were measured and then converted to radon concentration values. The radon concentration was found to range from 76.04 to 152.38 Bq m(-3) with an average value of 111.34 Bq m(-3) in the dwellings under study. (c) 2005 Published by Elsevier Ltd.
