226Ra and 228Ra in consumable marine organisms from different coastal regions of India

Marine organism samples were collected from different regions of India. The edible portions after drying and homogenizing kept for 1 month to achieve equilibrium between Radium and its daughter products, were analysed by gamma spectrometry using 50 % HPGe. 226Ra activity was found to be in the range of <0.07–0.736 Bq kg-1 (wet) and 228Ra in the range of <0.082–2.5 Bq kg-1. 228Ra and 226Ra concentrations in different species of organism were different even in the same marine environment. To assess the impact of this activity to human, ingestion dose due to consumption of organisms was calculated and the maximum dose of 2.8 μSv year-1 due to 226Ra and 25.24 μSv year-1 due to 228Ra was observed.
