    "ocrText": "COPY\nUNIVERSITY OF MISSOURI\nColumbia\nDepartment of Chenistry\nJune 11, 1935.\nDr. H. S. Miner,\nWelsbach Company,\nCloucester, New Jersey.\nMy dear Dr. Niner:\nI have received & little more information with regard to Dr. Lemen's\nillness, which may have a direct bearing on some of the questions in\nyour own mind 00 to the relative danger to health in writing with\nhigh-grade redium and mesothorium. It appears that Dr. Lenen has not\nbeen doing any work with high-grade materials for over a year: that is\nto say, he has done no crystallising of high-grade products and he has\nthis not been exposed directly to redium emenstion. It is true that\nhe usde some ressurements on some high-grade mterial but he 616 no\ncrystallising of high-grade interials. It coals, then, that his break-\ndown if attributable milt 031 to rediction from redium, is the result of\naccumulation in his system of redioactive products. In the radium\nseries, the products following redium 0 are some of them long-lived\nand they gradually produce products giving off alpha rays. Since some\ntime elapsed between his breakform and the years during which he was\nexposed to redium constion, there is the possibility that some of\nthese disintegration products resulting from the emanation my have\nremained in his system. In the therium series, on the other hand, the\nproducts which follow emanation are all comparatively short-lived, and,\nhence, if these disintegration products from the emanations have at all\nattributed to the illness of these men, it would seem that the radium\nproducts are the ones responsible.\nAll of these surmises are, of course, more guesses: one is as good as\nthe other, but we who are now thinking closely about these things should\ngive some consideration to all these theories. The fact that Buckley's\nassistant who did the greater part of the recent work still has a normal\nblood count may not prove, as you seem to think, that the exposure to the\nradiations was not the primary contributing factor in Buckley's case.\nIt may be that the responsible products begin to show their effects, only\nafter the lapse of some time after exposure. Would it not be a matter\nof safety to have Dob's blood taken again after a month or two has passed 7\nwith very kind regards and good wishes, I remain\nVery sincerely yours,\n(Signed) Horman Schlundt.\nHS:VH"
