Tritium concentration in different parts of the rice plants, grown in villages around Tarapur Atomic Power Station, west coast of India, exposed to continuous atmospheric tritium in field condition were studied during two harvesting seasons of the years 2016 and 2017. The TFWT (HTO) and OBT concentrations in different parts of the rice plants were determined along with tritium in soil and air. The HTO to OBT concentration ratio in rice and hay was greater than unity in majority of the samples.
