摘要

Our environment is constantly emitting radiation from natural radionuclides embedded in earth, soils, living materials and cosmic sources. As we basically live with radiation and this radiation is mainly due to natural occurring radioisotopes, a correct assessment for the radionuclides we enclose in the buildings we live in or deploy our daily activities may raise specific concerns. In this paper we performed a dose and radiation risk assessment of specific major radionuclides present in common building materials. In order to achieve this, two type of residential buildings were analyzed – one flat on second floor of a building so that the soil radon emissions can be ignored and a house built on the ground level, currently being under construction. The estimated annual equivalent dose value for the house is 0.27 mSv/y and for the flat is 0.34 mSv/y. The determined dose levels are both under the maximum values allowed by the national and international regulations.
