SLIDE 54 Body-burden history at Bikini. Three body burden measurements of the Bikini Island population werg,conducted from 1974 to 1978 at Bikini Island. this time, the mean During Cs body burden of the adult Bikini population increased by a factor of 20. This dramatic elevation of body burden appears to be solely attributable to increased availability of locally grown food products, specifically coconuts and coconut plant products. An ingestipg intake model for stepwise increasing intake was used to estimate total Cs radioactivity ingested at Pikini. A constant continuous intake model was used by us to estimate total Sr intake.
