Staffing: Seven were associated with this project, three i BRL (two military, one civilian), three from the 930lst TSU (t military, one civilian), and one military from NAU. Project Report: Reference 49. Nuclear Radiation (Program 2) This program had two major objectives: (1) documentation the ini- tial neutron and gamma radiation from large-yield nuclear detonftions, and (2) documentation of fallout from large-yield surface detonatiaqms. out information from large-yield detonations was available only MIKE detonation of Operation IVY (1952), and this was limited wind and crosswind from the burst point. An ambitious program Fall- from the data up~- was insti- tuted for CASTLE to study the downwind deposition of weapon debris. planned effort and unplanned incidents following BRAVO resulted This in much information about fallout from the CASTLE shots. Project 2.1 -- Gamma Radiation Dosimetry Agency: Signal Corps Engineering Laboratories (SCEL) ¥ Operations: Films and chemical-dosimetry vials were installed in shel- ters from 1 to 15 nmi (1.9 to 27.8 km) from ground zero on islands and reefs of both atolls (18 islands and throughout the perime r of Bikini and 10 along the northern section of Enewetak). ions were St activated as late as possible and information was recovere radsafe conditions permitted. as soon Helicopters were used to thef extent possible. Shots: BRAVO, ROMEO, KOON, UNION Radiation Exposure Potential: (Bikini); NECTAR (Enewetak). Exposure potential existed fbr those activating the stations subsequent to BRAVO and for all pergBonnel involved in recovery. Staffing: SCEL. Three people were associated with this project, One was a civilian, and the others were military. Project Report: Reference 50. 177 11 from as
