Sr /sup 90/ concentrations were determined in milk samples obtained in 13 cites and towns in the Emilia, Romagna, and Marche Abruzzo districts of Italy during July and August 1961. Sr/sup 90/ was separated by evaporating the milk, ashing the residue, precipitating it as the nitrate, and counting it as the carbonate. The mean value for all samples taken was 5.9 pC/l, which is considerably lower than the levels of 1l to 20pC/l found in Milan in 1958 and 1959 and the values of 17 and 34 found by the Centro di Studi Nucleari at Ispra in 1959. However, they are higher than the levels recorded in Czechoslovakia in 1957 (3.5), 1958 (6.4), and 1959 (5). It is pointed out that the present milk samples were obtained before resumption of nuclear testing by the U.S.S.R. and U.S.A. in 1981 and 1982. The levels are far below the max permissible limit of 80 pC/l. (BBB)
