An extensive training program was initiated by the unit some six months in advance of operations in order that a skilled group of technicians could be available to the unit. Four Navy electronic technicians attended a four-week instrument repair course at the U.S, Navy Atomic Defense School, three Navy medical technicians attended a special two-week radiochemical laboratory course at Evans Signal nv ehavet 11ahs cbRelat Laboratory (ESL), and eight Army photo-dosimetry technicians also attended a special one-week course at ESL. The unit conducted several project monitor schools to qualify project personnel in the fundamentals and techniques of radiationsafety. The first school was conducted at the Nevada Proving Grounds in the second week of November, 1953. A second school was conducted at the Eninman Rad-Safe Center in the middle of February 1954. A third school was conducted at the Parry Rad-Safe Center early in April 1954. A total of some 275 AEC and project personnel were qualified as project monitors as a result of these courses and similar courses . Cog tt at NRDL, UCRL and EG and G. A general indoctrination course was conducted for TG 7.1 and 7.5 personnel through the use of AFSWP training films covering basic physics of atomic weapons, medical aspects of nuclear radiation, and field decontamination. These films were shown along with the usual movie programs at all camps at Bikini and Eniwetok. 4.6.4 Control Element The control element exerted supervision of TG 7.1 and 7.5 activi- ties within radiologically-contaminated areas. Control stations were established at Parry, USS Bairoko, USNS Ainsworth, USS Curtiss and USS Estes. Radiological situation data was maintained in the form of situation maps at these stations. These maps were used to control activities in contaminated areas. These stations constituted clearance stations for all working parties entering contaminated areas of 100 nr/hr or greater. Records of activities within contaminated areas were maintained as a check on film-badge exposures. In several cases personnel exposures were revalued from information gathered from these preentry forms. Several instances were noted in which individual film badges had high readings of exposure but investigation revealed that the film badges had been left in highly contaminated areas and did not represent actual exposure.
