RADIOACTIVE FALLOUT IN ISRAEL. PART 1. MEASUREMENT OF THE TOTAL DEPOSITED ACTIVITY AND OF THE RADIOACTIVITY OF THE AIR. Final Report for 1958 and 1959

OSTI ID:4112544
The fall-out of radioactive debris from nuclear bomb tests was collected at seven stations throughout Israel during 1958 and 1959, and its beta activity and decay properties determined. Fall-out levels followed the same average trends at all stations. Activity peaks found throughout 1958 could be related to the nuclear tests conducted during that year. In addition to this effect, increased amounts of old fall-out were noticed during the spring of 1958 and 1959. The activity collected during 1958 was generally of mixed origin. However, the activity peak of spring 1959 could be related almost entirely to the October 1958 Russian test series. Fresh fall-out was found to be predominantly in the form of a number of hot spots while older material was more homogeneously distributed. Rain was found to be the main deposition agent, although in a manner complex to analyze. The decay properties of the fall-out were found to be reliable indicators for identifying nuclear clouds and tracing the movement of air masses. (auth)
