Методология подхода к экспресс-оценке величины радиационного риска для здоровья населения при воздействии радионуклидов, присутствующих в подземной воде

The methodological approach for the express-estimation of the value of individual lifetime cancer risk due to the groundwater use by population for drinking is supposed. The calculation of risk is performed with the use of only the values of specific activity of 226Ra in underground water. The formulas for calculating the value of individual lifetime cancer risk in the groundwater use by the population in drinking aims for oral and inhalation routes of exposure are suggested.
