THE Sr-90 FALLOUT AND THE AIR MOTION

Journal Article · · Papers Meteorol. and Geophys. (Tokyo)
The cumulative amount of Sr-90 in Tokyo through the middle of 1958 reached 11.3 mc/km/sup 2/. The fall rate of Sr-90 has the positive correlation of +0.69 with the rainfall amount but it has no spring maximum as suggested by Machta et al. The estimated amount of fallout in the future will be about 50 mc/ km/sup 2/ even if nuclear tests stop now. The average age of fallout which is calculated from the ratio of Sr-89 and Sr-90 was from 200 to 300 days. The differencs between the atmospheric ozone and the Sr-90 in the stratosphere is discussed. It is concluded that the radioactive deposit on the carth is affected by locations and seasons of injection of Sr-90 into the stratosphere as well as the turbulent motion on a larger scale. (auth)
