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 than that of the previous four years, the global cumulative deposit of {sup 90}Sr continued to decrease because of radioactive decay. By the end of 1986 the global cumulative deposit of {sup 90}Sr had decreased to 343 PBq. 23 refs., 4 figs., 12 tabs.
