UNIVERSITY OF MISSOURI COLUMBIA DEPARTMENT OF CHEMISTRY MAY 24 1934 May 22, 1934 Mr. H. H. Barker U. S. Radium Corporation 535 Pearl Street New York City My dear Barker, Last fall the Maywood Chemical Works had Mr. Hill, who is engaged in their mesothorium refining up to the bromides, come to Columbia to be tested for radioactivity. We found him to be entirely negative. We advised the Maywood people to have this operator watched carefully both as to blood count and electroscopic measurements. We have no doubt that the Maywood Company would like to have Mr. Hill measured again by me at the time I shall be in New York City. What I wish to find out is whether the U. S. Radium Corporation has the gamma-ray electro- scope used by the U. S. Public Health Service and if you have it conveniently available would you permit me to use this instrument in making a test on Mr. Hill. Let me say that I have a Wulf Quartz-fiber Gamma Ray instrument of my own, but if I could avoid taking the in- strument on the trip it would be a little convenience. No doubt Dr. Flinn would be very glad to loan me the old Gamma Ray instrument, but the drift of that instrument is nearly 10 times that of the new instrument and one would therefore be uncertain about the results obtained for a microgram or two of radium. With very kind regards, I remain, Sincerely yours, Horman Sahlundt Herman Schlundt hs:ik
