V. RADIATION SAFETY A. GENERAL. _— Teo Se : . . ‘ wt Sedcergag ez gre BL ap Jaete ~ 1 2S “4.SQoi 2 It op sme Epi ce ten ce The level of radioactivity at Enewetak Atoll, as reported in the AEC Survey, is sufficiently low that persons may visit almost every location there without fear of being exposed to radiation in excess of established radiation protection guides. Cleanup is needed, however, because these guides would be exceeded if persons were to dwell throughout the Atoll. Cleanup itself needs radiation safety precautions because possibilities exist that previously undetected contamination will be uncovered, stockpilin of contaminated debris will enhance local radiation intensity, and cleanup activities will make plutonium more readily available for assimilati before it is contained. The safety precautions will result from a - cleanup radiation safety policy which complies with the Federal guides, as well as makes every reasonable effort to maintain radiation exposure ‘. as low as is reasonably achievable taking into account the state of technology and the economics of improvements in relation to benefits to health and safety, a and ether societal and socioeconomic considerations.

The military radiological safety regulations will apply to all individuals who are at Enewetak Atoll during the period of Cleanup. Personnel not under control of DNA shali comply in all respects with the regulations or be denied access to Enewetak Atoll.

In such cases, adequate alternate safety procedures will be established. re . y, . Pia sae Be an C. RADIATION AREAS.
