Abstract: In the present work, radiation doses are estimated from the analysis of ⁴⁰K, ¹³⁷Cs, ²²⁶Ra and ²²⁸Ra radionuclides in marine fish of the Bay of Bengal, accumulated in ten different human organs: red marrow, lung, thyroid, lower large intestine, upper large intestine, small intestine, breast, stomach, gonads and bone surface. The lowest equivalent dose is calculated in the thyroid as 2.7×10⁻³ µSv/y and the highest on the bone surface as 1.1×10⁻¹ µSv/y. The effective dose due to ²²⁶Ra is the highest (1.2×10⁻¹ µSv/y) in the whole body, whereas the lowest dose is for ⁴⁰K (3.6×10⁻² µSv/y).

Keywords: radiation doses; human organs; marine fish; fish consumption; low radiation.
