Abstract
The present study was intended to explore the naturally occurring radioactive materials in the selected areas of Kashmir Division. The study was carried out in with the help of experimental method. SSNTDs in track etch technique has been used in the present study due to their simplicity, low cost, non-destructive, small size, and having integrating capability for large scale studies for the measurement of radon activity, and radon exhalation rates studies in various samples. In the present investigations the observed values of mass exhalation rate and surface exhalation rate in soil and sand samples are usually less, comparable with other Indian studies reported for soil and sand samples of nearby areas, except for Rajpora area which shows high mass exhalation rate.
