Letters Received to Dr. H.S. Miner, June 11, 1925

COPT UNIVIRSITY 07 MISSOURI Columbia Deportment of Chenistry June 11, 1935. It. H. S. Viner, Telabach Company, Oloucester, New Jersey. Ny dest Tr. Niner: I have received S little more information with regont to Dr. illness, thich may have a direct bearing on sone of the questions in your oim mind DE to the relative danger to henlth in worldag with high-grade rediun and mesothoris. It appeszs that Dr. Lenon has not been doing any vorle with higlegrade unterials for over a that is to my, he has done no crystallising of high-grade products and he hes thrs not beon exposed directly to redium It is true that ho asde some on some miterial but he 454 no crystallising of T° then, that his broals dom if attributable mb so from às the remult of accomintion in his system or products. In the radium serico, the producto following redimm o sare sone of then long-lived and they gratually produce prodnets giving off alpha rays. Since somo tine olapsed bethreen his and the yeara during which he was exposed to redium connation, there is the possibility thit sone of these disintegration products resulting from the commation may have remsined in his system. In the thoriun series, on the other hond, the products which follow enanation are all comprotivoly short-lived, and, hence, $ these disintegration products from the exentions have at all attributed to the illness of these men, it would seem that the radiun products are the ones responsible. All of these surmisos are, of course, more guesses; one is as good os the other, but we vho are now thinking closely about these things should give some consideration to all these theories. The fact that Buelley's assistant who are the grenter part of the recent worl: still has a normol blood count any not prove, as you seem to think, that the exposure to the radiations wes not the primary contributing fnetor in moldey's case. It may be that the responsible products begin to show their effects, only after the lapse of some time after exposuze. Would it not be a matter of sofety to have Bob's blood taken agnin ofter a month or tiro has passed ? with very kind regards and good vishes, I remain Very sincerely yours, (Signed) Schlundt. HS : VH
