Tables showing the recent data on the dose of ionizing radiation received by man in various conditions are pree sented, and the extreme importance of systematic monitor- ing of radioactivity in the atmosphere is stressed. reget » Gunter SUREMENTS OF LONG-RANGE PALLOUT IN RIO a. aaeerRe 1 4g, Wee72h53 = English).

The potential radioasatrontium level to be expected in the skeletons of growing children as a result of environmental contamination was computed. Results are based on available data on the rate of bone remodeling and ex~ change, the rate of skeletal growth, and the level of Sr9Y in the biosphere. Lebedinskii, A.
