DRAFT TFM: SA: ADHP June 1, 1973 RADIATION PROTECTION GUIDANCE FOR CONTROL OF EXPOSURES AT ENIWETOK ATOLL INTRODUCTION Standards for protecting man from exposures to ionizing radiation have been developed concurrently with development of nuclear technology. Authorities at the national and international level using conservative assumptions have developed approaches for radiation protection and established numerical standards which in their view provide a level of safety at least as stringent as is achieved for cther powerful agents, As activities with nuclear radiation and radioactivity have become more numerous and complex, standards have evolved for broad categories of exposure conditions. These standards are directed toward use by governmental agencies and other responsible bodies in their health protection activities. A major consideration in development of standards is that they be simple to understand and easy to apply in order to avoid misinter- . pretation, In considering real situations, use of judgement rather than rigid application, im the extreme, is favored recognizing the benafits as well as risks associated with radiation usages. It has been anticipated that situations will arise for which available standards are not directly applicable. Such cases are to be consicered on a case-by-case basis, with judgements made as to exposure levcis that P Ife = eee . = | : BCGL hwLAA9 048 ao , Po - me IlA eee 7 +e 8 5 FERRYEr mn seas
