Mr. Barker - 2 - 6-18-31
zone of safety. (I see that this is airing my own views. I
am not confining myself very closely to remarks on your
criticisms). What I wish to point out is that there is no
real cause for alarn when the quantities of radium gathered
are so far below the amounts which formerly have proved
damaging or fatal. This point should receive special men-
tion in the report and by se doing the alarm and damaging
impression will vanish.
When you say on p. 2 that the survey has over-
emphasized its efforts in examining workers who were employed
prior to 1926, I feel that you make an unfortunate implication;
for the survey includes all workers now employed in dial paint-
ing; all those employed prior to 1926 and all those (74) since
1926. How can we get a true picture of the present situation
unless we examine all the workers? I advise expunging this
paragraph from your discussion.
Your selection of 4 from the 74 persons employed
since 1926 as radioactive, presents a. viewpoint which Dr. Leake
will doubtless wish to make sone mention of in revising the re-
port.
The small quantities of thoron, are with one ex-
ception, quite negligible.
Graph 12, to which I referred before, records
results of measurements, and so I do not question it.
It would be desirable to compare radon content
of air breathed by brush painters with that of normal air. The
radon content of air breathed by workers is only about 200 to
500 times that of normal Chicago air, so why worry? A radon
content to constitute a hazard must be several thousand times
that of ordinary air.
I agree with you that some of the conclusions are
given in a form which is too general. Some qualifying or ex-
planatory clauses might well be included.
You have rendered a distinct service in your care-
ful analysis of the report, but I do not agree with you in all
your criticisms.
The olock manufacturers can doubtless reduce the
hazards by 50% by following the suggestions given in the report.
Sincerely yours.
