COPY 33 Nemorandum in the Case of Carlowh VS. United States Radivo Corporation On Thursday, June lith, I interviewed Doctor Martin Ssanalotald, consulting chemint of the New Jersey Department of Labor, at the plant of the Turton T. Bush Company of pelamenna, of which he is the The Doctor told me that he had boen advised a yenr or so auro that some of the employees of the United States Radium Corporation vore suffering from a condition of the jaw, which preatly resembled that which has horetofore bean associated with phosphorus. Some time later he lesrned that there were additional cases. and at the request of the Department, ha made an annlysis of the luminous material uged by the Redium Corporation to ascertain whether or not it contained phosphorus A very enroful analymis was made, as a result of which he found that there was absolutely no phosphorus or any phosphate or other substances which, DO far as he Jnow, could be turned into phosphorus when combined with other elements or chemicals.
