APPENDIX J RADIOLOGICAL-SAFETY REGULATIONS 3.1 REGULATIONS The total permissible dose for personnel participating in Operation Ivy is 3.9 r (measured gamma only), based on a three-.nonth operational period. No limitation is placed on the rate of accumulation of the total dose permitted for the operation so long as the rate is sufficiently low to rermit adequate control. Special rules apply to sampling-aircraft pilots, Individuals or groups working in contaminated areas, or with contaminated equipment, will be accompanied by Rad-Safe monitors. During recovery operations the Rad-Safe monitor will aci in an advisory capacity to keep the recovery-party leader informed of radiation intensities at all times, The recovery-paity leader is expected to accept this advice and act accordingly. It is the responsibility of both the leader and membersof the recovery party to adhere to the limits establishe:' in this Appendix. . Namesof all individuals who are expected to enter radioactive areas subsequent to a test will be submitted to CTG 132.1 in the form of an eligibility list two weeks prior to the test. All islands in the atoll will be considered contaminated after each test until reported clear by CJTF 132. No radioactive material will be removed from the test site, except as authorized in experimental program plans. Unauthorized entry into radioactive areas is prohibited. Prior to entering a contaminated area, the monitor will issue appropriate equipment, consistiag of film badges, dosimeters, and such protective clothing as may be required. Work parties will wear appropriate face masks if the radiological monitor deems it necessary. On leaving a contaminated area, all persons will return film badges and dosimeters to the monitor and will dispose of bootees and gloves. The monitor will check personnel for contamination and process those contaminated throvgh the personnel-decontamination station. Ail personnel workin” with radioactive materials will wear protective clothing and/or gloves as indicated. Safe handling of highly radioactive materials will be ensured by the proper use of additional protective equipment, such as tongs and remote-handling devices. J.) PERMISSIBLE CONTAMINATION LEVELS Permissible contamination levels stated below are to be regarded as advisory limits for the general guidance of Rad-Safe personne! attempting control of contamination under average conditions. These limits may be adjusted upward or downward under special circumstances, as directed by CTG 132.1. All readings of contamination levels are to be made with side-window G-M counters, the counter tube walls of which are not substantially in excess of 30 mg/cm’, with the beta shield open. When possible the surface of the probe should be held 1 to 6 in. from the surface under 94 | . ' _
