Grygorieva L. Integral radiation load on man in the Southern Ukraine

By conducted in Southern Ukraine radioecology and dosimetry researches a two factors exposure (industrial and residential environment) of employees granite mining granite processing industry of radon-222; a level of radiation exposure of man from the tritium, which comes through evaporation from reservoirs manufacturing plant and through cultures which are irrigated are first established. The "chernobyl accident" radiation exposure for the population of the southern region in 1986 year and annual effective dose of radiation in after 1987 year are first refurbished. For operational forecasting radiation exposure at first established the dose coefficients ("dose rates") of natural and man-made sources of ionizing radiation in southern Ukraine for the main dose of radiation pollutants; the model of radioecological risk of the influence unit of natural and man-made sources of ionizing radiation are the first time established. Determined by the expected life effective dose of radiation from these sources. The research results allowed to develop of the methodology of integral radiation exposure of man from natural and man-made radioactive sources and to propose countermeasures to reduce it. The results of the research allowed to ground for solving important scientific problems - finding and implementing new and effective measures to optimize and improve radiation protection, and confirms the need to use stochastic methods of forecasting radiation exposure of a person when evaluating radiation risk from the effects of natural and man-made sources of ionizing radiation. A new direction in dosimetry is suggested: an integral approach in assessing the radiation exposure of man from natural, technological-reinforced natural radionuclides and "the station" and "Chernobyl accident" radionuclides.
