Cohmbia University College of Physicians and Surgeons EPIDEMIOLOGY 437 WEST 59TH street, NEW YORK INDUSTRIAL HYGIENE PUBLIC HEALTH ADMINISTRATION INSTITUTE OF PUBLIC HEALTH SANITARY SCIENCE Sept 11 1925 Mr. A. Roeder, United States Radium Corporation, New York Citym N.Y. Dear Mr. Roeder's I have just completed our blood examination of the persons engaged in using your luminous material in Connecicutt. I am glad to say that the picture presented by these persons contains nothing that is of an alarming nature. One would expect to find a similar pictuee if one were to examine any group of the same age and living conditions and not engaged in this industry. So far we have examined 45 girls twenty two percent of whom have worked five years or more in the industry, and seventy five per cent over a year. Half of them I think have had extractions in that time and suffered no ill effects, My animal experiments are still negative. As soon as I get my report from Mr. Barker as to the radium contents of some material I will render you a prelinary report. I am enclosing a list of questions that I wish you would answer if you can SO I can complete my study. Sincerely yours F.B. Flinn
