Rongelap Island 2 years after the March, 1954, nuclear detonation,
readily detectable amounts of both ..beta..- and ..gamma..-radiation
were present. The activity was attributable to /sup 60/Co
(I) to the
extent of 63 and 85% of the gross ..gamma..-activity. As it is not a
component of fission products, it is assumed that it was induced from
an environmental precursor possibly /sup 59/Co, by the neutron flux
accompanying the detonation. It was not detected in samples collected
one year after the detonation; this points to an enormous concentrating
capacity of Tridacna gigas.;

Abstract: A radiochemical analysis of sea water containing fission
materials collected near Bikini Atoll in June, 1954, was performed.
sea water was boiled with hydrochloric acid,
each 5 mg as Fe and La were added to it.

The
iron and lanthanum salts
They were precipitated as
which was dissolved in hydrochloric acid and ferric chloride
was extracted with ethyl ether. The remaining solution was evaporated
to dryness and the residue was dissolved in hydrochloric acid. Using
the latter solution the group separation was done with cationexchanger
resins.;
