Baseline radionuclide concentration in commercially important brachyuran crabs around Mumbai and Sindhudurg of Maharashtra, India

Present study was conducted to generate baseline data on radionuclide concentration in commercially important crabs around Mumbai and Sindhudurg districts of Maharashtra, India. The activity concentration of 238 U, 228 Ra, 40 K and 210 Pb were calculated in different tissues of crabs for different species, with respect to seasonal and spatial variations. The order of accumulation was gills > exoskeleton > muscle. The study shows that the observed values varied depending upon the species, locality and environmental factors.
