Scose: (a) 200 Word Summary: <A special field trip will be made in August 1978 to do in-vivo counting and urine bioassay at Xwajalein Atoll on 20 to 30 Bikini residents before their anticivated exodus from Bikini in late August. In addition, a separate field trip party will proceed to Bikini to collect 24 hr urine samples from those Bikini residents who cannot be accomodated cn the charter fl'zht which will bring the in-vivo counting subjects to Kwajalein. The rationale for this effort is as Sllows: (1) Accurate internal dosimetry for 13765 body burdens in the Bikinians requires an assessment of extant body burdens just prior to the departure orf the people from 3ikini. (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. Determina- tion of these parameters is essential to the accurate assessment of total dose commitaents. (3) During the past several years the Bikinians have become apprehensive about potencial health effects which they feel might result from their having iived in the contaminated Bixini environment. The personal attention that they will receive in these personnel monitoring activities should help to alleviate some of their fears. 15. Relationshio to other Projects: This program is directly related to our on-going environmental and personnel monitoring efforts under the 3NL Marshall Islands Radiological Safercy Program. 16.
