Estimation of radiation dose inside residential buildings in the area of Banovici and Zivinice, Bosnia and Herzegovina

The main aim of this study is to measure the indoor gamma and beta radiation dose rates in the areas of Banovici and Zivinice, Bosnia and Herzegovina, and their dependence on meteorological parameters (temperature, pressure, and air humidity). During the research, emphasis was placed on measuring doses in private residential buildings. Using the Gamma-Scout device, gamma and beta radiation dose rates were measured inside the residential buildings. Annual effective doses were estimated, as well as the excess lifetime cancer risk resulting from gamma and beta radiation. The average estimated annual effective dose of gamma radiation in the Banovici and Zivinice areas was 1.09 ? 0.20 mSv, and also for gamma + beta radiation, it was 1.14 ? 0.19 mSv. The excess lifetime cancer risk due to exposure to gamma radiation indoors was estimated to be (4.25 ? 0.77)?10-3, while this risk from exposure to gamma + beta radiation was estimated to be (4.47 ? 0.75)?10-3.
