fhe talend of Bikini was surveyed most extensively. The former village
was loceted here,. ond remains the most desirable locetion for permanent
housing.

The beech sree, Village site, and selected transects across the

miédle end doth enfs ef the island were surveyed for rediation levels. The
dose rete st or eer the beaches was lowest due to lesching ead wash off ef

rediosctivity. Mpdistion levels vere comersble to those found ia the U. 8.
(10 R/hour). Migher levels (roughly twice to three times beech values)
were present in the. interior (densely overgrown) regions.

Other measurements imiicated redicectivity to de present in the vegetation.
Bence ome may comcluode thet as the shielding effect of plant material is.
reacoved, the doee* froa ground de;ceition com-ensates for the removal of

Plowing

wader, or othervise burying the top layers (inch or so) of soil should eub-

stentielly reduce the dose rate. As expected, the residusl redicectivity

1s ell reletively long-lived: ¢s/5! comtributes 70-80 percent of the externel
dose.

Thus only e slow decrease with time can be expected from radicective

decay?
Pleat end sniuel tissue conteined verying amounts of fission and

ectivetion jroducts. Pre-1946 Bikintas diet consisted predominantly of
fish, vith ,enfienes fruit, ecdconut, errow-root, and land crebs supplying e

Imported foods euch es dried milk, canned meats, flour, ont

rice were seldom used by the Bikial people prior to 1946.

Contects with the

outside world doubtless have temied to alter former tastes.
