hag to do for the Industrial Hygiene Service
and the numbers of samples that are involved.
MR. I.B. WHITNEY: The analytical
problem consists of three major groups of
gamples, one which we do for the Industrial
Hygiene - these sare the bioeagsay samples
which concern uranium in uranium air dust
and soil or whatever it may happen to be that
they go out and get samples for;
also small
quantities of beryllium in air dust or urine,
radium periodically, rafion in breath samples,
thorium in urine or sometimes in soil semples,
fluoride sulphates in air dust,
I think we have done a few and also
e011 samples for background data at various
plants about to be started,
We also have a sunshine program for
which we mak2 “serfium", strontium, some iodine,
barium and various other chemical analyses.
We have had a program which has
followed very much the same type of radio=-
chemical analysis including a few others
such ag zine and rutheniun,
We had an fodine program during the
early part of the year,
