Krypton - 85 in the Atmosphere: Accumulation, Biological Significance, and Control Technology (Ncrp Reports Ser. : 44)

"This report...is concerned with the accumulation and biological significance of 85Kr in the atmosphere, and the possible techniques available for its control. 85Kr is released to the atmosphere through nuclear weapons tests and the generation of nuclear power. With the cessation, for the most part, of atmospheric testing of nuclear weapons, 85Kr in the atmosphere results primarily from the reprocessing of nuclear fuel, very little 85Kr being released from the actual operation of the nuclear power plants themselves. This report estimates the future global concentrations of 85Kr in the atmosphere resulting from projected future levels of nuclear power use, the absorbed doses to man resulting from these concentrations, and possible techniques which may prove practicable for the future control of 85Kr atmospheric levels."
