PHYSICAL ASPECTS OF THE RADIOACTIVE FALLOUT OVER SCANDINAVIA ESPECIALLY DURING THE PERIOD OCTOBER 1958-OCTOBER 1959

Technical Report ·
OSTI ID:4122147
Data are summarized on fission-product activity during the period from October 1958 to October 1959. Measurements of airborne activity were made both above and below the tropopause layer. The effects were studied of heavy stratospheric injections from nuclear tests during 1958, after a year free from nuclear tests. lt was estimated that about 40 megatons of total fission energy was released during l958. About 20 megatons were released during the tests in the Arctic during September and October, 1958. The measured abundance of various nuclides indicates that the bulk of the heavy fall-out over Scandinavia was injected during October l958. Data are tabulated. (C.H.)
