30-year cumulative dose (Eneu, .27 rem; Bikini, 3.5 rem) (6) is relatively
further below the standard (5 rem) than the initial annual one.
Although the above external dose estimates are quite adequate for
planning, it is to be noted that specific beta-ray exposure measurements at
ground level

(0-10 cm above surface)

have not been published

for Bikini.

The Committee is therefore recommending that such measurements

be made to

make the estimates complete.
