Transfer factor of 137Cs from soil to wheat grains and dosimetry around Narora Atomic Power Station, Narora, India

Abstract

This field study was undertaken to quantify the transfer factor of 137Cs from agricultural soil to wheat grains and ingestion dose evaluation around Narora Atomic Power Station, Narora, India from 2010 to 2012. 137Cs activity was measured using NaI (Tl) well type gamma-spectrometry system. Transfer factor of 137Cs from soil to wheat grain samples was in the range of 0.12–0.46. Annual ingestion dose to man from 137Cs activity was significantly lower than permissible limit (1.0 mSv year−1). The risk measured due to 137Cs is also insignificant to members of public residing around Narora Atomic Power Station, Narora, India.
