Radiological Safety Regulations CJTF SEVEN No, 3 53 for routine work is not realistic. The regulations set forth herein have been designed as a reasonable and safe compromise considering conservation of personnel exposures, the international import of the test and the cost aspects of operational delays chargeable to excessive radiological precautions. In all cases other than emergencies or tactical situations the ultimate criteria will be limited by the MPEs for personnel. Special instances may arise such as in the case of an air-sea rescue within the RADEX or in the case of tactical situation in which operations will be carried out without regard to the MPEs and MPLs prescribed herein. For such emergency or tactical operations the criteria prescribed below for tactical situations will be used as a guide. Wherever possible, however, film badges will be carried and RadSafe monitors will accompany such operations to determine the extent of the actual radiation hazard experienced in order that appropriate medical action may be initiated. Task force radiation dosage control will start on first shot minus fifteer (15) days and terminate upon departure of individuals from the forward area or on the last shot plus fifteen (15) days, whichever occurs first. All personnel will be considered to have arrived at the Pacific Proving Ground by first shot minus fifteen (15) days. Prior and subsequent to this period, radiation dosage control will be as prescribed by CTG 7.5. 5e a. The MPE for personnel involved in this operation, as defined by paragraph 4, above, is 3.9 roentgens (gamma only). This exposure may be acquired at any time during a thirteen (13) week period of the operation. Provided no previous over-exposure remains for compensation, 3.9 roentgens may be acquired without regard to the individual's past radiation history, This MPE will be considered further augmented (without separate action) by 0.3 roentgens per week for each week in excess of thirteen (13) weeks required during the operational period defined by paragraph 4, above. b. A special MPE of 20 roentgens (gamma only) is authorized for the operational period as defined by paragraph 4, above, for crew mem=pers of air sampling aircraft. c, All exposure to external gamma radiation will be regarded as total body irradiation. Those individuals exposed to ionizing radiation in excess of the value computed by paragraph 5a, above, will be informed that appro- priate remarks will be included in their medical records. Military personnel in this category will be advised that they should not be exposed to further radiation until sufficient time has elapsed in order to bring their average radiation dose down to 0.3 roentgens per week, Civilian personnel in this category will be informed that limitations on further radiation exposure will be as determined by the laboratory or agency having administrative jurisdiction over such personnel. All atoll land and lagoon areas in or near which a detonation takes place will be considered contaminated until cleared for operations by the task force commander. Entry to and exit from contaminated areas will be via RadSafe check points only. Contaminated land and water areas will be delineated as such, Personnel entering these areas will be subject to clearances by the N-J-2
