Abstract
Coal based power accounts for 70 % of energy generation in India. In this study, radiological characterization around Kolaghat Thermal Power Plant was undertaken. Radiochemical analysis of coal, ash and soil samples was performed using High purity germanium (efficiency 50 %). The characterization was done based on ‘Radium equivalent activity’, dose rate and hazard index. High radioactivity was observed within a radius of 500 m from the ash ponds and it decreased beyond 500 m. The overall radioactivity of the area was observed ~3–4 times higher than the prescribed limit, and the hazard index was estimated as unity.
