Letters Sent to R.E. Miller, July 12, 1926

quad lo lo July 12th, 1926. n. E. Miller, Ceo Hamiltos Tatch Company, Lancaster, Pa. Dear Mr. Miller: Inclosed herewith you will find an article entitled "Radio Active Material an Industrial Hazard?", by Dr. Trederick B. Flinn, Ph. D. Assistant Professor of Physiclogy in Indástrial Hygiene, College of Physicians and Surgeons, Columbia University, which treats of the so called #radium necrosis" or radium poisoning cases. The investigation by Dr. Flinn, which formed the basis of his article, has been by far the nost thorough and far reaching work undertaken on this subject. This article will apperr in one of the early issues of the Journal of the American Medical Association, While it soems that the charge of "redium poisoning" caused the death of several girls (which charge was widely advertised through the press a few months ago) is entirely unfounded, we naturally hesitate - without further investication - to maice the broad statement that radium in luminous matorial is unhameful, although wa bolieve this to be the case. Therefore, in order to be on the safe side, we caution you, if you have not already done 30, to order your operatore not to point their application brushes between their lips. Whenevor we receive any further authentic information on the subject, we shall be glad to pase it along to you Youre very troly, President. CBLEE-OB Inclosure (1)
