MUAMANOMEN stea lo soT lo .omoM gnhewzaA July 12th, 1926. Radiun Products, Inc. 2171 W. Washington Boulevard, Los Angolos, California. Attentions- Mr. H. S. Bryan, Vice President. Gentlement- Enclosed herewith you will find an article entitled "Radio Active lintorial an Industrial Hasard?", by Dr. Froderick B. Flinn, Ph. Dee Assistant Professor of Physiology in Industrial Hygiene, College of Physicians and Burgeons, Colunbia Univorsity, which treats of the so called necrosis" or radium poisoning casos. The investigation by Dr. Flimm, which formed the basis of hie article, has been by far the most thorough and far reaching work undertaken on this subject. This article will appeaz in one of the early issues of the Journal of the Amerioan Medical Association. Whlle it seems that the charge of "radium poisoning* caused the death of gevernl girls (which clarge tas widoly advertised through the press a for months a.go) is entirely unfounded, wo naturally hesilate - withous furthor investigation - to nalce the broad statement that radiuz in luninous material is unharmful, although we believe this to be the case. Therefore, in order to be on the safe side, we caution you, 1f you have not already done 30, to order your operators not to point their application brushes between their lips. Vhenever we receive any further authentic information on the subject, tre shall be glad to pass it along to you. Yours very truly, Presidente CBLEE-OB Enclosure (1)
