Abstract
Abstract Natural radioactivity is ubiquitous, while the anthropogenic radioactivity is introduced into the environment due to manmade activities. The members of public (MOP) get exposed to both natural and anthropogenic radioactivity through the various routes of intake. The ingestion dose to MOP from natural (40K, 210Po, 226Ra, and 228Ra) and anthropogenic (90Sr and 137Cs) radionuclide through the consumption of benthic and pelagic marine biota collected from Thane creek, Mumbai was investigated. It was observed that 99.9% of ingestion dose is from natural radionuclide while, the anthropogenic radionuclides are contributing just 0.1%. Hence, the dose from anthropogenic radionuclide’s due to the consumption of marine biota is negligible compared to that from natural radionuclide’s which is also an insignificant contribution in the overall dose exposure to man.
