Title: Worldwide deposition of strontium-90 through 1990

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.
