The average monthly fission prcduct activity in daily ground-level air samples collected at 24 meteorological stations in Canada was found to decrease from about 0.85 dpm/m/sup 3/ in August 1959 to about 0.3 dpm/m/sup 3/ by the end of the year. The average monthly fission product activity in precipitation samples collected at 9 sampling stations was found to increase from about 25 mc/ mi/sup 2/ in January, 1959 to about 65 mc/mi/sup 2/ in April, 1959. Subsequently, the average monthly fission prcduct activity in precipitation samples collected at 24 meteorological stations was found to decrease to about 5 mc/misup 2 in December, 1959. The average Sr/sup 90/ content of milk powder sample collected at 16 milk powdering plants during 1959 was found to increase from abcut 11 micro micro curies per gram calcium in January to about 21 in June. The level then decreased to about 12 in September before increasing again to about 15 micro micro curies per gram calcium in December. The Sr/sup 980/ content of hunnan bone samples collected from 97 subjects during 1957 and 1958 ranged from 0.38 to 5.9 micro micro curies per gram of calcium for children and from 0.07 to 0.82 micro micro curies per gram of calcium for adults.
