THE UNIVERSITY OF KANSAS LAWRENCE DEPARTMENT OF PHYSICS AND ASTRONOMY Jan. 17, 1946 The U. S. Radium Corp. JAN 21 1946 535 Pearl Street New York City, N. Y. Attention: Mr. Wallhausen Dear Mr. Wallhausen: Greetings! Although I have left New York, I am still carrying on work for the U. S. Public Health Ser- vice in connection with protection against radium dust. In addition I am hoping, in cooperation with Dr. Downs of the Biology Department here, to do some honest to goodness research in connection with the metabolism of radium, particularly as related to the deposition of radium in the bones of experimental animals. In this connection we will need about 2 milli- grams of radium in the form of chloride which can be fed to the animals or injected intravenously. When I say 2 milligrams, I mean + or ", since it need not be accurately measured before we get it. We will have to divide it into the desired doses, each of which will have to be measured. I am wondering whether U. S. R. would care to sup- ply us with this amount of radium and what the cost will be. We should like to get it as soon as possible. I would be much interested to know what the outcome of your studies with Dr. Flynn and Dr. Hess have been in connection with the relation between breath radon con- centration and rate of exhalation. With kindest personal regards, I am Sincerely yours, BrankE Holcker Frank E. Hoecker Assoc. Prof. of Physics & Astronomy Consultant, U.S. Public Health Ser- vice feh/ks
