Abstract

Strontium-90 results from the Environmental Measurements Laboratory`s (EML) Global Fallout Program (GFP) are presented for the years 1987 through 1990. Quarterly {sup 90}Sr deposition results for the 66 sampling locations of EML`s GFP were generally low, indicating that there was no significant release of fission products into the atmosphere during this period. The global {sup 90}Sr deposition during these 4 years was lower than it has been for any similar period since this program began in 1958. Since there was no major atmospheric source of {sup 90}Sr during this period, the global cumulative deposit of {sup 90}Sr continued to decrease by radioactive decay to a 27 year low of 311.4 Pbq.

Worldwide deposition of strontium-90 through 1986

Technical Report Monetti, M; Larsen, R

The major source of {sup 90}Sr deposition during 1986 was the {sup 90}Sr released into the atmosphere following the accident at the Chernobyl nuclear power reactor station in the USSR. The deposition occurred mainly in the Northern Hemisphere. The {sup 89}Sr and {sup 90}Sr deposition reported by EML for May 1986 suggest that most of the deposition occurred immediately following the accident. A total deposition on the surface of the earth of 1.7 PBq {sup 90}Sr during 1986 was estimated using samples assumed to be representative of the global fallout. Although the {sup 90}Sr deposition in 1986 was greater thanmore »« less
Worldwide deposition of /sup 90/Sr through 1983

Technical Report Larsen, R

The total deposition of /sup 90/Sr in the Northern Hemisphere during 1983 was 0.3 PBq, while the total deposition in the Southern Hemisphere was 0.2 PBq making the total deposition on the surface of the earth during 1983 0.5 PBq. This is the lowest total yearly deposit since the initiation of the Environmental Measurements Laboratory's global fallout program in the late 1950's. The worldwide cumulative deposit decreased to 365.6 PBq. The last reported nuclear detonation in the atmosphere occurred at the Lop Nor test site in China on October 16, 1980. 13 refs., 9 figs., 6 tabs.
Worldwide deposition of /sup 90/Sr through 1982

Technical Report Larsen, R

The total deposition of /sup 90/Sr on the surface of the earth during 1982 was 0.7 PBq. This is the lowest total yearly deposit since the initiation of the Environmental Measurements Laboratory's global fallout program in the late 1950's. The worldwide cumulative deposit decreased to about 374.0 PBq. The last reported nuclear detonation in the atmosphere occurred at the Lop Nor test site in China on October 16, 1980. 12 references, 9 figures, 9 tables.
Worldwide deposition of /sup 90/Sr through 1985

Technical Report Juzdan, Z

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.
Worldwide deposition of /sup 90/Sr through 1984

Technical Report Larsen, R; Juzdan, Z

The deposition of /sup 90/Sr in the Northern Hemisphere during 1984 was 0.3 PBq (0.008 MCi), while that of the Southern Hemisphere was 0.1 PBq (0.003 MCi). This resulted in a total deposition on the surface of the earth during 1984 of 0.4 PBq (0.011 MCi). This is the lowest total yearly deposit since the initiation of the Environmental Measurements Laboratory's global fallout program in the mid-1950's. The worldwide cumulative deposit decreased to 357 PBq (9.6 MCi).
