performed on the distribution of final doses the above discussion about t
uncertainty in the input parameters would indicate that a reasonable
estimate of the potential maximum dose would be three times the dose listed

in the tables.

This dose would be expected to occur in a very small

fraction of the population.
A significant feature of the dose analysis is the tremendous reduction
in potential dose to Enjebi (Janet) residents if coconuts from Enjebi
(Janet) are removed from the diet and replaced by coconuts from Southern

Islands.

For this option, maximum annual dose rates for a "maximum

individual" ere less by nearly a factor 3 than when coconut came from Enjebi

(Janet) Island (tables 29, 30 and 36),

Again this emphasizes how important

the diet is in estimating doses at the atoll and the importance of imported
foods in reducing potential doses.
The two scenarios used for estimating the dose to children are for
Enjebi (Janet) Island living pattern because it
