title: Measurement of radon exhalation rate and soil gas radon concentration in areas of southern Punjab, Pakistan.
abstract: Plastic track detectors were used to measure the radon concentration and exhalation rate from the soil samples. The samples were collected from areas of southern Punjab, Pakistan. In a laboratory experiment, passive alpha dosemeters were installed inside cylindrical bottles containing the soil samples. The radon concentrations and the radon exhalation rate were found in the ranges of 34 +/- 7 to 260 +/- 42 Bq m(-3) and 38 +/- 8 to 288 +/- 46 mBq m(-2) h(-1), respectively. The on-site measurements of radon in the soil gas were also carried out in these areas using a scintillation alpha counter. The concentration of radon in the soil gas was found in the range of 423 +/- 82-3565 +/- 438 Bq m(-3).
