But these
Steaming vats had tremendous algae growths around the edge,

They in turn absorbed--and there was

EISENBUD:
Lauren, iron-63 is an interesting nucleide,

I wonder have you looked for Lron-55 in the fish over the

atoll?
DONALDSON:
Yes.

DUNHAM:
Yes,
In fact, it's the No. 1.
I would think so, yes.
Yes,
My recollection from a visit to Bermuda
19
a few years ago is that one of the marine scientists there
20
said that iron availability in the waters around there was
21
the limiting factor in perhaps the whole food chain inasmuch
22
as one the key algae couldn't go farther than the amount of
23
iron available.

You m@an phosphorus was not the limiting
factor?

EISENBUD:
Iron,
We found, in studies of our own staff in
28
the laboratory, that some of our ladies who eat tuna fish a
29
few times a week have blood levels of iron-55 that are about
30
ten times higher than the rest of the staff,
31
look at the Pacific tuna, which I think was done independently
32
by the Hanford people, and they came to the same conclusion,
33
that it was Lron-55 from the fallout,
This led us to
