Estimation of Radon Exhalation Rate and Radium Content in Soil Samples of Pathankot District, Punjab Using LR-115 Plastic Detector

چکیده
In the present investigation, soil samples were collected from 10 villages belonging to Pathankot district, Punjab, India and assessed for radium content using LR-115 plastic detector. The ‘track etch’ technique has been employed for measuring the radium content. From the radium content, radon exhalation rates and mass exhalation rates were calculated for these samples. The mass exhalation rate in soil samples has been found to vary from 1.91 mBqkg-1h-1 to 6.55 mBqkg-1h-1 and radium concentration varies from 1.39 Bq/Kg to 5.31 Bq/kg. A strong correlation (correlation coefficient= 0.99) has been observed between radium and radon exhalation rate. The radium content in soil in the study area is below the safe limit recommended by UNSCEAR [1].
