Committee, which includes a medical doctor, a DoE representative, and a representative from each of the Service elements, monitors the overall radiation safety program. In addition, an independent audit and inspection team of experts headed by the Director, Armed Forces Radiobiology Research Institute, and including representatives from DoE, the three Services, and AFRRI visit the Atoll on a quarterly basis to ensure the program is being properly implemented. In order to assure compliance with these standards and insure that any exposure is kept to a minimum, access to the contaminated islands is rigidly controlled. When personnel do work on these islands, it is under the supervision of the Radiation Control Committee, and under the constant Surveillance of a Field Radiation Support Team. This team monitors the local radiation environment, continually samples the air for airborne activity, determines the level of protective equipment needed, and monitors personnel for contamina-— tion. Specific procedures have been formulated to provide detailed day-to-day guidance on safety and other procedures pertaining to operations that might involve radiological contamination (copies attached). Although the low gamma radiation levels found at Enewetak Atoll would not normally require a full-scale dosimetry program, we have chosen to establish one. All personnel who work on, or visit, the contaminated northern islands (the controlled islands) are issued a film badge on a monthly basis. Self-reading ionization chambers (pocket dosimeters) are also issued, as required, to supplement the film badge program, and are read on a daily basis. Whenever earth-moving operations are to be conducted in contaminated areas, water sprinklers are set up to minimize resuspension of contamination. During transit the trucks are wet-down and covered with tarpaulins for the Same reason. Air samplers are set up immediately downwind of the operation to monitor any airborne hazard.
