| Abstract: | The coal-mining area
of the foothills of Mokokchung District, Nagaland bears significant geological
features. Radon exhalation from ground plays an important role in enhanced
indoor radon levels. Exhalation rates (mass and surface) from coal and soil samples
of the area have been studied using LR-115 (II) nuclear track detectors. The
mass and surface exhalation rates from coal samples varied in the range
9.7-16.2 mBq/kg/h and 323.5-538.6 mBq/m2/h, respectively. The mass
and surface exhalation rates from soil samples varied in the range 11.1-15.2
mBq/kg/h and 368.3-507.6 mBq/m2/h, respectively. The study has
revealed substantial presence of radionuclides in the coal and soil of the
area. |
