is about three
times that of previous estimates ( Dunning,
1957: Cohn ef af... 1960). Those estimates
were based on an estimated daily intake of
0.8 vy of calcium, or about three times the
value reported here. Thus. the significant
ditference between this and previous values
reflects a discrepancy between observed aud
estimated calcium intake. It is not svithin:
the scope of this report to enter ito an
estimation of body burden, which has been
discussed in detail by Cohn et ad. (1960).
Flowever, it is of interest to uote that the

greater than four or that these samples do
not correctly represent daily caletum intake.

Rations containmy the higher levels ot
zine-63 also contain the higher levels of
stable zinc, indicating that local sea ioods
may be the main source of zine in the diet.
Cesium-137, strontium-90, and cobalt-00
show no definite correlation with potassium,
calcium, and cobalt, respectively, indicating
that these elements are in large measure
supplied from imported foods.
