Juzdan, Z R

The total deposition of /sup 90/Sr on the surface of the earth during 1985 was 0.2 PBq, with approximately equal amounts deposited in the Northern and Southern Hemispheres. This is the lowest total deposit since the initiation of the global fallout program of the Environmental Measurements Laboratory in the mid-1950's. The cumulative deposit of /sup 90/Sr decreased to 264 PBq in the Northern Hemisphere and 85 PBq in the Southern Hemisphere, making a worldwide cumulative deposit of 349 PBq (9.4 MCi). 25 refs.
