M JUAMAROMEN HOIMSTMI stea lo 10% Josidu? do .omeM July 12th, 1926. Dr. L. M. Boyers, First National Bank Bldg. Berlseley, California. Dear Dr. Boyers: Enclosed herewith you will find an article entitled "Radio Activa Naterial an Industrial hazardi", by Dr. Trederick B. Flinn, Ph. D., Assistant Professor of Physiology in Industrial Hygione, College of Fhysicians and Surgeons, Colunnia University, which treats of the so called "radium necrosis" ox vadium poisoning cases. The investication by Dr. Flinn, which formed the basis of his article, has been by far the most thorough and far reaching work on this subject. This article will appear in one of the sarly issues of the of the American Medical Association. Mhile it seems that the charge of "radium poisoning caused the death of several girls (which chargo was widely advertised through the pross a fow months ago) is entirely unfounded, we naturally hesitate - without further investigation - to make the brond statement that radium in luminous material is unharmful, although we believe this to be the case. Therofore, in ordez to be on the aníe wa paution you, if you have not alrondy dono so, to order youx operators not to point thoir application brushos batwoen thoir lips. Thenover we zoceive any further authentie information on the subject, ve shall be glad to pasa it along to you. Yours very truly, Presidente CBLEE:OB Enclosure (1).
