BRLeBp AQAPLT Brig. Gen. Thomas E. Lacy, USAF Commander Field Command Defense Nuclear Agency Kirtland AFB, New Mexico 87115 Dear General Lacy: As requested, a short description of ERDA planned radiological monitoring of nuclear test impacted Pacific atolls is provided. ERDA followup activities related to nuclear tests conducted in the Pacific and resettlement of the residents of Bikini and Enewetak Atolls has been directed toward: 1. Assessments of environmental radiation and radioactivity levels on islands and atolls that received close-in fallout from J.5. nuclear weapons tests in the Pacific. 2. Development of estimates of projected doses and associated risks for those who inhabit islands affected by fallout. 3. Development of recommendations for cleanup, rehabilitation, and use of test atolls in accord with NEPA and Federal radiation protection requirements. 4&. Support of DOD and DOI cleanup and rehabilitation field operations at test atolls. 5. Long-term radiological monitoring followup of the environment and people of the test and near-test islands in the Northerm Marshalls. After cleanup and rehabilitation, followup monitoring of Bikini Atoll and the people living in that atoll was begun. This consists of one or more visits to the atoll each year by an ERDA survey team. Radiation monitoring and sample collection activities are planned and implemented that will provide basic data for assessing the total radiation exposures of island residents considering both external and internal emitters. of urine collected. Whole body counting is performed and samples Samples of marine and terrestrial biota, particularly those in the hamen food chain, are collected for analysis along with airborne particulates, water, and soil.
