December Operation ?lan CTG 7,3 No, 1-53 Force SEVEN 7.3 25, D.C. 1953, 1200R Appendix I to annex 6 Radiological Sefety iteculations 1, The Maxirmn Permissible Exposures (MrBs) and Maxinur. rervissible idiiaits (HvLs) as stated herein cre applicable to a field experimental test of nuclear devices in peecetine wherein numbers of personnel engared in these tests hrve been previously exposed or will be continuously exposed to potential radiation hazards, It may become necessary from c study of personnel records to reduce the MrE for certain individuals who heve recently been ever~exposed to radinticn, Further, the MPEs and Mrlg are subject to revision by waiver fron the Task Ferce Conmander in individually designated ceses when clreunstences indicate the need and Justifiertion therefore. 2. Due to the special nature of field teats it is considered that a policy of strict adherence to the radiological standerds prescribed for routine work ig not realistic, The regul: tions set forth herein hrve been designed es 2 reasonable and safe compronise considering conservrtion of personnel exposures, tne internationel impert of the test and the cost aspects of operational aelevs eharzeeble to excessive radiological precnutions, In all cases other than emergencies or tretical situntions, the ultinate criteria will be linited by the MPEs for personnel, Special instances nay orise such as in the case of an air~sea rescue within the Headex, or in the cese of a tactical situation, in which operations will be cerried out without reverd to the MPEs end MeLs prescribed herein, For such emergency or tactical operations the criteria prescribed below for tactical situations will be used as a euide. Wherever possible, however, film badges will te carried end KedScfe monitors will accompany such operations to determine tne extent of the aetucl radiation hazerd experienced in erder thet appropriate medical action may be initiated, 3, a The MPE for personnel involved in this operation is 3.9 roentgens (eanma only), Tris exposure ney be acquired at any time during a thirteen (13) week period. Yrovided no previous over-exposure reneins for com pensrtion, 3.9 roentgens nay be cequired without regard to the individuals past rediction history, Tnis MrE will be considered further augmented (without separete oetion) by 0,3 roentgens/week f or eacn week in excesa of thivyteen (13) weeks of the operational period, b. All exposure to external gamma rredintion will be regarded as total bedy irradiation, G-L~1
