THT ge ere | nuclear devices in peacetime wherein numbers of personnel e gaged in these tests have been previously exposed or will be continu usly exposed to potential radiation hazards. It may become necess ry from a study of personnel records to reduce the MPE for certain individuals who have recently been over-exposed to radiation. Further, the MPEs and MPLs are subject to revision by waiver from the task fodce comman- der in individually designated cases when circumstances ind need and justification therefor. Due to the special nature of field tests it is considered t icy of strict adherence to the radiological standards presc routine work is not realistic. The regulations set forth h been designed as a reasonable and safe compromise consideri vation of personnel exposures, the international import of and cost aspects of operational delays chargeable to excessi logical precautions. In all cases other than emergencies or Situations the ultimate criteria will be limited by the MPEs sonnel. Special instances may arise such as in the case of t a polibed for ein have conser tactical for pern 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 an MPLS prescribed herein. For such emergency or tactical operation the criteria prescribed below for tactical situations will be used S a guide. dSafe Wherever possible, however, film badges will be carried and monitors will accompany such operations to determine the ext nt of the actual radiation hazard experienced in order that appropriat medical action may be initiated. Task force radiation dosage control will start on first shot fifteen (15) days and terminate upon departure of individual forward area or on the last shot plus fifteen (15) days, whi curs first. All personnel will be considered to have arrive Pacific Proving Ground by first shot minus fifteen (15) days. and subsequent to.this period, radiation dosage control will prescribed by CTG 7.5. a. The MPE for personnel involved in this operation, as defin paragraph 4, above, is 3.9 roentgens (gamma only}. This expo be acquired at any time during a thirteen (13) week period of eration. Provided no previous over-exposure remains for comp 3.9 roentgens may be acquired without regard to the individua radiation history. This MPE will be considered further augme (without separate action) by 0.3 roentgens per week for each excess Of thirteen (13) weeks required during the operational defined by paragraph 4, above. b. A special MPE of 20 roentgens (gamma only) is authorized f operational period as defined by paragraph 4, above, for crew of air sampling aircraft. 452 inus from the
