Body-burden historyat Bikini.
Three body burden measurements of the Bikini
Island population werg,conducted from 1974 to 1978 at Bikini Island.
During
this time, the mean
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 ingesti
intake model for stepwise increasing intake was used to
estimate total
Cs radioactivity ingested at fikini.
A constant continuous
intake model was used by us to estimate total
Sr intake.
