T GLadstone 5-3670 William T. Davin, M .D . William B. Frymark, M .D . Artknr P. LeBeau, M .D . INDUSTRIAL CLINIC 9701 West Grand Avenue Franklin Park, Illinois 60131 May 23rd, 1967. Robert A. Kehoe, M.D. Professor Emeritus of Occupational Medicine University of Cincinnati Department of Preventive Medicine Cincinnati, Ohio 45219. Dear Dr. Kehoe: I wish to thank you for your reply to my request regarding information concerning the toxicity of lead in occupational conditions. Your information was quite pertinent, and has helped us to solve our initial problems at the Motorola Company in Franklin Park, Illinois. Me realise that we have a long way to go in controlling the occupational hazards in the manufacturing of television tubes. However, our initial problem was to determine at what level individuals should be withdrawn from the exposure of lead, and what were the best methods of testing both the blood and urine. I needed some definite criteria in which to work with, in order to present to the manufacturing people. Incidentially, we have been able since the onset of my relationships with the lead problem in the tube manufacturing in this company, to reduce the average blood lead level of the employee from 67 micro grams percent to 31 micro grams percent. This has been done entirely by individual instruction, respirator mass, and "good housekeeping". The actual manufacturing methods have not changed, and at the present time, I cannot foresee any actual changes in their handling of the leadoxide in this area. Thank you again for your kind consideration and prompt information. Yours truly, William T. Davin, M.D. Class of 1952 University of Cincinnati College of Medicine.
