Measurement of radon exhalation rate and soil gas radon concentration in areas of southern Punjab, Pakistan.
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).
