ASSESSMENT OF RADIATION HAZARD OF CONCRETE AND BACKGROUND RADIATION INDOORS

Simulation of the dose rate of building materials γ-radiation in the premises of different designs has revealed the minimal levels of human exposure. It was determined that the exposure dose rate at the given points of a single room depends on the content of natural radionuclides in construction materials and the changing geometry of a person's exposure in the premises. When the exposure dose rate of γ-radiation above an individual plate is determined, it is conventionally divided into the discrete sources, the dose rate from several plates is summed up.
