Letters Sent to H. Mead, June 26, 1928

June 26th,1928. H. Mead, Esq.. 8457 San Juan Ave. , Southgate, Calif. Dear Sir: In reply to your letter of June 10th, we are glad to give you such information as we believe may help to sorve your problem. The material used in our plant for applying to watch and clocic dials is light andalpha ray sensitive zinc sulphide. This material con- tained no phosphorus, but dédscontain a varying amount of radio-active materials for sensitization. We do not believe that this situation is in any way comparable to the use of the common radio-active drinking waters. In the first place such waters contain only very small amounts of radio-active materials, and secondly these radio-active materials are necessarily the gaseous disintegration product of radium, namely - radon,which is short lived. We are not in a position to recognize that the cases which have been iven so much publicity are legitimate ones. These cases were founded by building public opinion from a homanitarian aspect, tather than on their merits. There is to be created a medical Board to study these particular girls, and it is our hope that this Board will eventually charify the situation as to whether these girls are or have been suffering as a result of their employment. Very truly yours. Vice President. H Barker:RH
