Abstract
137Cs and 90Sr concentration in rice grain and corresponding agricultural soils were measured (2009–2011) within 15 km radius of Narora Atomic Power Station (NAPS), Narora, India. 137Cs activity was in the range of BDL (<0.2)—0.65 ± 0.18 Bq kg−1 in rice grains and from BDL (<0.56)—2.06 ± 0.36 Bq kg−1 in soil samples. 90Sr content was BDL (<0.095 Bq kg−1) in all rice grain samples. Transfer factor of 137Cs from soil to rice grain was in the range of 0.10–0.40. Ingestion dose from rice consumption was significantly lesser than the permissible limits of 1.0 mSv year−1, thus posing no radiological health risk.
