Transfer coefficient from grass to milk (Fm) for 137Cs and 40K was computed based on the activity measurement data in the respective matrix at Kakrapar Gujarat site, India, during 2013 - 2019. The annual geometric mean value of 137Cs activity in grass and milk samples varied from 0.13 to 0.48 Bq/kg dry wt. and 0.03 to 0.14 Bq/l, respectively. Activity observed during the year 2013 - 2019 is comparable with preoperational baseline activity level, which indicated its fallout origin. The site-specific Fm has varied between 1.0E-02 to 3.71E-02 d/l with a GM of 2.22E-02 d/l (137Cs) and between 6.69E-03 to 1.54E-02 d/l with a GM of 9.63E-03 d/l (40K), respectively. The annual effective dose due to the ingestion of 137Cs and 40K through milk consumption was found to be 0.036 μSv/y and 16.94 μSv/y, respectively. The result is an useful input for the estimation of radiation dose to human beings in accidental conditions.
