Measurement of radioactive nuclides present in soil samples of district Ganderbal of Kashmir Province for radiation safety purposes

Assessment of radioactive elements in the residential area is very important from different points of view especially for human health. The aim of present survey was focused on determining the current radon exhalation rate and radium concentration in soil samples collected from some areas of the Ganderbal district, Jammu and Kashmir, India. “Can technique” has been employed for the measurement of radon exhalation rate and radium concentration in soil samples collected from under study areas. The Uranium concentration in these soil samples where estimated by using the fission track registration technique (using LR-115 plastic track detectors).The uranium concentration was found to varies between 2.03 and 3.52 ppm. The radon exhalation rate in these samples has been found to vary from 5.05 to 21.89 m Bq kg−1 h−1. Radium concentration in soil samples varies from 6.43 to 18.89 Bq kg−1. The calculated values of Uranium concentration in these soil/rock samples are quite lower than the risk level. Radon and radium values found in these samples are also lower than that of optimum value. Hence these areas can be considered as risk free zones from human health point of view.
