Aw
be reps pov year or 50-2 per yoar fron the external stuff -599-2 from the internal,
There is a protty good dese ywhon you
consider the fish lived to be about two yoars old.
I do not
think this is an exhorbitant fiscure, but if we get to the point
where we cut it in tvo, we have 759 to a thousand hours over 2
life svan, waich is a pretty sood cose, and I think that is
because the fish, to grow more slowly -- I think it is whet
shortened their life snan and I am not at all sure but what it
is wnat caused the white crappie and the red horse to disappaar
from tha population.
There is one other thing I would like to say kafore
Ioquit.
If all of you have copies of this, I vould like to have
you open to page 33, because bere ve have this picture of the
seasonal accumulation of radioactive materials in the fish, That
is a story protty much in itselz in that when we first started
out in the fall of 1950, we found thet the fish were carrying
a reasonable anount of radioactivity in the tissues.
The following suzmmer, they had doubled
or tripled
and immediately we thought here was a thermal enimal and it
vould change its metabolic rate as the temperature of the
environment chanses, so let us ses iz he dees not have a seasonal
variation in the accumulation of radiation materials.
We cut up
three black cravpies and three biucgills each week from late in
Ausust of 1951 until early in“the spring of 1953.
I do rot
renember what the dates weve, but it was sometime in February or
