High Altitude Sampling Program: radioactivity in the stratosphere
Technical Report
·
OSTI ID:6269264
Radioactivity data are presented from the High Altitude Sampling Program's aircraft (Project Airstream) and balloon (Project Aschan) studies for the years 1981 to 1983. Gross gamma, gamma spectral and radiochemical analyses of filter samples were carried out. Quality control samples, along with the air samples, were analyzed and the results are presented. Inventories for the Northern Hemisphere stratosphere of /sup 137/Cs, /sup 144/Ce, /sup 90/Sr and /sup 239/ /sup 240/Pu are also included. Based on our measurements made in 1981 and 1982 for /sup 90/Sr, the stratospheric half residence time was found to be 6.5 months and this is a reduction from the previous value of 10 months. The total stratospheric inventory of /sup 90/Sr for July 1982 (4 kCi) is the lowest since 1963, when inventories were first started. 77 references, 26 figures, 36 tables.
