Assessment of Environmental Radioactivity Level and its Health Implication in Imiringi Community Bayelsa State, Nigeria

A total forty two (42) sampled points were investigated for radioactivity level and health implication using standard method. the exposure dose rate ranged from 14 to 32μrh^-1 with an average value of μ23rh^-1. dose rate and equivalent dose rate ranged from 121.8 to 278.4ngyh^-1 and 1.18 to 2.69msvy^-1 respectively. the average value of the indoor annual effective dose equivalent (aede), outdoor aede, and excess lifetime cancer risk (elcr) were computed to be 0.936 msvy^-1, 0.311 msvy^-1 and 0.810 x 10^-3 respectively. analysis of dose to human organs; testes and ovaries, were 0.61 and 0.43 msvy^-1 respectively. exposure rate, dose rate and elcr exceeded the recommended values. all the outdoor aedes were within the permissible value of 1.0 msvy^-1 for general public and below the limit of 20 msvy^-1 for radiological workers as recommended by international commission on radiation protection (icrp).
