ON THE SUBSTANTIATION OF INITIAL SCREENING GROSS ALPHA ACTIVITY CONCENTRATION LEVEL FOR DRINKING WATER SAFETY ASSESSMENT ESTABLISHMENT

Abstract

The present work gives an analysis of the data on natural radionuclides content in drinking-water of Russian Federation groundwater supplies obtained in long-term investigations. On the basis of the mentioned analysis estimation of population internal exposure doses from the drinking-water consumption is carried out and optimal value for initial screening gross alpha activity concentration level is suggested.
