Measurements of Mass and Surface Exhalation Rate from Soil of Eastern Haryana, India

摘要

Radon is the inert gas which is important for indoor radiation dose. More than half of radiation dose received by human being from radon. Radon is the decay product of radium which depends upon the radioactivity in building materials. Radon exhalation rate from the building material is an important issue. The radon mass exhalation rate and thoron surface exhalation rate have been estimated by means of SMART RnDuo in surface soil samples collected from Eastern Haryana. The radon mass exhalation rate and thoron surface exhalation rate are varied from 9.8 to 34.1 mBq/kg/h and 170.5 to 542.8 mBq/m~2/s with average value 19.01 mBq/kg/h and 370.38 mBq/m~2/s, respectively.
