Radiological Safety Regulations CJTF SEVEN No, 3 «2 for routine work is r-* realistic. The regulations set forth herein have been des: *ned as a reasonable and safe compromise considering conservation cf personnel exposures, the international import of the test and the cost aspects of operational deiays chargeable to exces— Sive radiological precautions. In all cases other than emergencies or tactical situations the ultimate criteria will be imited by the MPEs for personnel. Special instances may arise such as in the case " of an air-sea rescue within the RADEX or in tie 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 ag a guide, Wherever possible, however, film badges will be carried and RadSafe monitors will accompany such cperations to determine the extent of the actual radiation hasard experienced in order that appropriate medical action may be initiated. Taek force radiaticn desage control will start on first shot minus fifteen (15) days and terminate upon departure of individuals from the forward area or on the last shot plus fifteen (15) days, whichever occure first Al personnel will be considered to have arrived at the Pacific Proving Ground by first shet sinus fifteen (25) days. Prior and subsequent to this period, radiation dosage control will te as prescribed by CIC 7.5. 5. a. The MPE fer personnel invoived in this operation, as defined by paragraph 4, above. .is 3.9 reentgens (gamma only) This exposure may be acquired at any time during a thirteen (13) week period of the operation. Provided no previous cver-exposure remains for com pensation, 3.9 roentgens may be acquired without regard to the indivwidual'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 opera- tional 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 ner- bere of air sampling aircraft. | c. All exposure to external gamma radiation will be regarded as total body irradiation. , 6. Those individuals exposed to ionizing radiation in excess of the value computed by paragraph Sa, above, will be informed that appro- priate remarks wili 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 dom 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 ‘urisdiction ower such personnel. i 7. All atoll land and lagoon areas in or nsar which a detonation takes place will be considered contaminated pntil cleared for operations by the task force commander. Entry to and exit from contaminated areas will be via RadSafe check points, only. I Contaminated land and water areas will be delineated as such. Personnel entering these areas will be subject to clearances by the
