flux model predicts wet season “plant transpiration rates nearly equar
to the 6 to 7 mm/d evaporation pan rate, which decreases to 2 to 3 mm/d
for the dry season. Radioisotopic analysis confirms the
microclimate-estimated 1:3 to 1:20 soil to plant /sup 137/Cs dry matter
concentration ratio. This ratio exacerbates the dose to man from intake
of food plants. Nephelometer measurements of airborne particulates
presently indicate a minimum respiratory radiological dose.;

Abstract: The purpose of this report is to refine the dose predictions,
subsequent to the cleanup effort, for alternate living patterns
proposed for resettlement of Enewetak Atoll. The most recent data
developed from projects at Enewetak and Bikini Atolls for concentration
and uptake of Cs, Sr, Pu, and Am were used in conjunction with recent
dietary information and current dose models to predict annual dose
rates and 30- and 50-y integral doses (dose commitments). The
terrestrial food chain in the most significant exposure pathway - it
contributes more than 50% of the total dose - and external gamma
exposure is the second most significant pathway. Other pathways
evaluated are the marine food chain, drinking water, and inhalation.;
