Bc a Project 21.3 ~ Short Half-life Activities - F, Monyer Project 21.3 was engaged in finding total tritium in the cloud. was done in the following manners Thie Carrier amounts of heavy water, krypton and xenon were added to the collection bottles prior to the program. The collection collection system consisted of filters for particulate matter and bottles mounted on the sampling planes. Gas samples were collected at to Parry verious altitudes and times following the detonation and returned for separation. Krypton, xenon, water and carbon dioxide were separated sample. from the gas semple and molybdenuz was separated from the filter per Krypton, xenon and molybdenum were collected to determine fissions collection tottle. 5 The remaining activities, ch4 and H? were returned to ation of total the laboratory, a6 barium carbonate and water for the determin tritium and possibly ct yield. The fisaion bottle data are shown in Table 21.31. SNL - £0 - LO
