Radon Activity and Radon Exhalation Rates From Some Soil Samples By Using SSNTD

Abstract

Radon exhalation rate from soil is one of the most important factors for evaluation of the environmental radon level. Solid State Nuclear Track Detectors (SSNTD ) has been widely used for the study of different aspects of radon emission from soil and others. In this paper, we are presenting the results of radon concentration, its exhalation rate and radium content in soil samples collected from different locations of refinery area belonging to Noonmati, Guwahati, Assam (India). The radon concentration varies from 380.95 to 457.14 Bq/ m3.The radon exhalation rates in terms of area and in terms of mass varies from 117.48 to 140.97 mBqm-2hr-1 and 3.32 to 3.99 mBqkg-1hr-1. The radium content varies from 5.34 to 6.40 Bq/ Kg. A good correlation is observed between radium content and radon exhalation rates in soil samples.
