Background: All generations of living beings have been and will be exposed to ionizing radiation. Until the discovery of radioactivity, man was not aware that ionizing radiation was a part of him and his environment. Humans are mainly exposed to gamma and beta radiation from terrestrial radionuclides, which represent the main source of irradiation of the human body. Materials and Methods: This paper presents the research overview of the dose rates of gamma and beta radiation, measured outdoors in the research locations by the Gamma–Scout device. The measurements were performed at fifteen locations in the area of Tuzla Canton, Bosnia and Herzegovina. The Gamma–Scout device was mounted outside on the table, at a height of 50 cm above ground in the vicinity of residential buildings in periods of 30 minutes. Results: The results presented include gamma, gamma+beta, and beta dose rate measurements. Based on these results, the annual effective doses originating from gamma and beta radiation were estimated. Results of measurements taken by this method showed that the values of the annual effective dose of gamma and gamma+beta radiation were in the interval of (0.21-0.32) mSv and (0.22-0.33) mSv, respectively. The estimated annual effective dose received by beta radiation was in the interval of (0-0.04) mSv. Conclusion: For all investigated locations, excess lifetime cancer risk (ELCR) was below the recommended risk value. |
