OFFICE OF THE DEAN

Mr. H. H. Barker
U. S. Radium Corporation
55 Pearl Street
New York, N. Y.
Dear Barker:
I expect to have occasion in the near future to apply phosphorescent
zinc sulfide to a glass surface. Would you please give me the formula of
the mixture I ought to make up? No radium will be used in it as it is to
be used as an indicator for external alpha radiation from an alpha ray
bulb which is to be used for lecture demonstrations. I had thought that
I would like to mix the phosphorescent zinc sulfide together with a small
amount of binder together with some other liquid which would evaporate readily.
If this is feasible, please specify the amount and kind of binder and sug-
gest an organic carrier.
I have just noticed in the paper the warning of Flinn about the drink-
ing of radium water which has caused the death of E. M. Byers of Pittsburgh.
What is your opinion of the drinking of water charged with emanation? Do
you believe that to be dangerous also?
With best regards,
Sincerely yours,
A. C. Lind
S. C. Lind,
Director.
