ge 2.4.2.8 2-45¢ Project 34.8. The objectives of Project 34.8 were: 1. Make the necessary measurements on QUINCE event to deleniate the fallout gamma radiation yleld produced by a surface detonation-on dandof al DELETED 2. DELETED Using data collect by this project and by Projects 34.9 and 34.10 construct a fallout model for use with any wind pattern, and evaluate extremes in militarily significant interesities for the same yield range. 3. Define the attendant plutonium contamination problem. The site for QUINCE event was Runit (Yvonne) Island of Eniwetok Atoll. Only about 400 feet of land in the prevailing downwind direction was available for radiation monitoring, necessitating placement of bulk of the instrumentation in the lagoon. There were 92 lagoon stations, 46 land stations, and 8 reef stations. The bulk of fallout instrumentation consisted of sticky pan fallout coll- ectors. Sticky pan collectors were mounted on small buoys in the lagaqon and on steel pipes in the reef area. After exposure, pans were counted in a fixed geometry. Lagoon and reef pan readings were calibrated in terms of full yield intensities by dose rate measurements over the available land and old flat-topped barges which were anchored in the lagoon. Dose rate readings on land and on the barges were made by hand-monitoring and by automatically recording instruments. 2.4.2.9 Project 34.9. Project 34.9 was responsible for photographing the cloud produced by the QUINCE event. The amin objective was to deter- mine the cloud dimensions as a function time. These measurements were necessary to assist Project 34.8 in constructing a fallout model, so pe 2.4.2.10 Project 34.10. One of the objectives of Project 34.10 was to measure the pre-shot wind conditions over expected cloud heights for the shot " time decision to assure that expected fallout would be adequately sampled by the instrument temporarily of Project 34.8. flO?ED ye aA, PAGE GS
