Letters Sent to Dr. Cecil K. Drinker, July 1, 1924

July 1, 1924. Dr. Cecil K. Drinker, Harvard University School of Public Health, 55 Van Dyke St., Boston, Mass. Dear Dr. Drinker: Thanks for your two letters of June 27, one enclosing report on films. There is another thought that has just occurred to me because we are doing practically no work in our Application Department. The Plant there usually has two boom periods in the year, one in the Spring and one in the Fall. We are now in the Summer slack time. It had not occurred to me before, but this fact may be important for you to know. Just a.s you found at Waltham, our operators do not work continuously. To make this thing practical, I am going to ask Mr. Viedt to summarize the records of employment of the various operators, particularly those who have been afflicted with the mysterious disease. If the records are complete, some very interesting data will be forth- coming. My impression is that most of these operators worked less than half a year whereas those in the plant who really handle Radium work pret ty much all the time. I will repeat again that I agree with you that all precautions should be taken, but I. still feel that we have to find the cause. Cordially, President. ARoëder-HM
