NATURAL AEROSOLS AND NUCLEAR DEBRIS STUDIES PROGRESS REPORT II

摘要

Some additional results of research on radioactive and inactive aerosols in the troposphere and stratosphere are presented. Results of studies of stratospheric particulate aerosols and of the size distribu-tion of fission products in the lower atmosphere are discussed. Tech¬niques of particulate aerosol collection and analysis are described. Results for barium-140 and strontium-90 in individual precipitation samples are presented together with preliminary meteorological in¬terpretation. Some results for gamma-ray activities in precipitation and soil samples are discussed.
