Measurement of natural radioactivity levels in Indian foodstuffs by gamma spectrometry.
Measurements of natural radioisotopes present in some of the foodstuffs which form the main components of the composite Indian diet are presented. Assessment of daily intake of these natural radionuclides has been made on the basis of the average daily intake of these food-items by the population of Bombay and its environment. The content of 40K, 226Ra and 228Th radioactivity varies from 45.9 to 649.0 Bq/kg, 0.01 to 1.16 Bq/kg and 0.02 to 1.26 Bq/kg, respectively. The average daily intakes of 40K, 226Ra and 228Th have been estimated as 105.6, 0.17 and 0.18 Bq d(-1), respectively for the period 1970-1982.
