APPENDIX REW&r OF RADLATION III PROTECTION STANDARDS The Task Group has considered a number of concepts in detising an approach to guidance for cleanup and rehabilitation of Enewetak Atoll, Notably, the concept that AEC accepting some and rejecting others. recommendations should consist of a series of alternatives or fall back positions uith the degree or level of radiation exposure reduction ultimately determined by some later deliberation based on factors The consensus of the such as availability of funds was rejected. Task Group opinion was that these recommendations should be and should establish a clear position on specific and unequivocal, what is needed, To do less would be unfair to the Federal agencies who have accepted responsibilities to perform the rehabilitations and to the Enewetak people who are looking to this agency for advice. ....... ......... .......... ............. / The judgement of the Task Group is that rehabilitation must conform with current radiation standards applicable for normal operations (not for accidenzs or for radialion workers) a~d vcith good health physics practice in implementing these standards. A sum-mary of current radiation protection standards and material related to health risks that may be associated with the standards re~tiewed and radiation criteria recommended by the Task Group follows. A. Federal Radiation Council (FRC) Basic FRC numerical guidance and health protection philosophy are similar to those of the ICRP and A~CRP. Radiation Protection Guides (RPG~ s) are provided which deal with exposures Actions are to be diof indi~id-~als and of population groups. rected primarily toward control of the sources ci radioactivity to _ restrict eritry into the environment. but also toward control of radioacb.ve materials after entry into the en~ironmeri in order The RPC1 s express the dose that to limit intake by humans. should not be exceeded .wdthout careful consideration of the Every effort should be made to encourage reasons for doing so. the maintenance of radiation doses as far below this guide as The RPG~s are intended for use \\ith normal peacepracticable.
