UNIVERSITY OF MINNESOTA SCHOOL OF CHEMISTRY MINNEAPOLIS RECEIVED APR 3 1928 OFFICE OF THE DEAN March 31, 1928 Walana Mr. H. H. Barker, Vice President, RADIUM U. S. Radium Corporation, MATERIAL EC 505 Pearl Street, New York. Dear Mr. Barker: Absence from Minneapolis has delayed my reply to your letter of March 19th. After studying the report of Dr. Drinker which you submitted to me sometime ago, and after our conference on this report with relation to the conditions in your plant, I have come to the following tentative conclusion: I do not feel justified in making any sweeping criticism of Dr. Drinker's report. In the first place I am not a medical man and would not be competent to discuss the pathological con- dition of those employees whose cases were covered in his report. I should, however, like to have seen a more complete anal- ysis of the state of health of all of your employees with reference to the nature of their work, the time which they had been employed, etc., than Dr. Drinker made. From Dr. Drinker's report it is clear that he found several cases where the pathological condition was so pronounced that he felt justified in concluding that they all arose from a common cause that must have existed in your plant. After an analysis of the various possible causes, he concluded that radium was the cause and from the stress which he laid on the dust hazard and from other statements in his report, it appears that he felt that the damage due to radium came from its introduction into the general blood circulation rather than from local causes in the mouth. This conclusion was rather surprising to me and I should not be able to accept it without further supporting evidence. On the other hand, I think Dr. Drinker's opinion that the number of cases was so great and so exceptional that there is no escape from there having existed a special cause in your plant, and I do not feel inclined to disagree with Dr. Drinker that this cause was radium in some form. Having then found myself in agreement to this extent with Dr. Drinker, there still remains the question as to whether your company was justified in disagreeing with his report at the -2- time it was rendered. This appears to me to be an entirely different question from agreement with it later with many more known facts at hand than you had at that time. I can find the following reasons why you might have been justified in disagreeing with his report: First, you had had several years' experience with several hundred employees engaged in handling radium before any unfavorable effects on them were observed. Second, the number of cases which Dr. Drinker found unusual was a rather small fraction of your total employees and since you were not at that time greatly impressed with the unusual nature of their affliction, you did not believe that they were so outstanding or that you had any special health problem in your plant. This state of mind on your part, together with your doubt of the dust factor in Dr. Drinker's report, would naturally prejudice you against it to a certain extent and you would therefore not rush into an acceptance of his recommendations. I do not know that there is anything in the foregoing that will give you anything more than some mental comfort or moral support. I do not know what the legal aspects of such a situation would be but I have been able to make that much reconcila- tion between your stand and Dr. Drinker's report. I expect to be in New York on Tuesday or Wednesday, April 24th - 25th. If any further discussion of these matters would assist you, I could arrange to see you at that time. With best regards, Sincerely yours, A.C.Lindi S. C. Lind, Director. SCL/CS
