Scove: (a) 200 Word Summary: <A special field trip will be made in August 1978 to do in-vivo counting and urine bioassay at Kwajalein Atoll on 20 to 30 Bikini residents before their anticinated exodus from Bikini in late August. In addition, a separate field etrip party will proceed to Bikini to collect 24 hr urine samples from those Bikini residents who cannot be accomodated on the charter flight which will bring the in-vivo counting subjects to Kwajalein. The rationale for this effort is as follows: (1) Accurate internal dosimetry for 13765 body burdens in the Bikinians requires an assessment of extant body burdens just prior to the departure of the people from Bikini. (2) There is evidence that both the short-term and long-term compartment l3/cs clearance rates from the Bikinians may differ significantly from those for the ICRP standard man. Determination of these parameters is essential to the accurate assessment or cocal dose commitnents. (3) During the past several years the Bikinians have become apprehensive about potential health effects which they feel might result from their having lived in the contaminated Bikini environment. The personal attencion that they will receive in these personnel monitoring accivities should help to alleviate some of their fears. L5. Relationship to other Projects: This program is directly related to our on-going environmental and personnel monitoring efforts under the 3NL Marshall Islands Radiological Safecy Progran. 16.
