The relatively low dose rates in most locations did not permit definitive assessments of beta dose rates by thermoluminescence dosimetry (TLD) during the 1975 survey. Beta dose estimates will be attempted in the village area and in the interior at Bikini Island by in situ beta counting and beta absorption measurements. The 1975 ground gamma survey data will be used to select approximately three locations for beta measurements in the village area and three in the interior based on observed gamma exposure rates. The subsistence garden in the village area will be observed for previously sampled items and for new items which may have matured since the 1975 survey. Selected plant items and associated surface soil will be collected for laboratory analysis. Samples of mature breadfruit will be collected depending on availability. Lastly, LiF TLDs left in the village area during the 1975 survey will be collected, and attempts will be made to buy or barter for specimens of local livestock for laboratory analysis of organ burdens for various radionuclides, Nam-Bokata Complex Two approximately north-south running transects will be cut through the vegetation at Nam Island. The approximate routes will be determined from enlarged high altitude aerial photographs taken during the 1975 survey, and supplied to us by EG &G,Inc., Measurements will be made of external gamma and beta exposure rates at selected identifiable sites along each transect, cco habe Approximately three vertical soil profiles will be obtained along tot hoad on a marks. and at other accessible sites on the island near recognizable land-
