    "ocrText": "August 15th,1928.\nDr. Elizabeth B. Bricker,\nChief,Hygiene and Sanitation Section,\nDepartment of Labor and Industry,\nHarrisburg,Pa.\nDear Dr. Bricker:\nYour letter of August 9th is at hand, and I shall\nendeavor to answer same in the abgence of Mr. Lee.\nWe are aware that the Hamilton Watch Company, have\nhad their employees examined by Dr. Froderick B. Flinn of the\nCollege of Physicians and Surgeons,New York City, whom we consider\none of the best versed men in this field. Dr. Flinn has had more\nexperience with these cases than any other individual, and is a\nman who is very thorough, and leaves no stone unturned for the full\nprotection of the employees.\nlle have encouraged all of our clients tho use any\nappreciable amount of material to have their employees examined at\nfrequant intervals, as we believe by such examinations the possibility\nof a hasard in this industry may be precluded.\nWhile it is true that our material is made in\ndifferent degrees of luminosity, depending upon the amount of radio-\nactive constituints present, still we do not advise our clientsas to\nthe amount of radiom in our compounds, which may vary from timo to\ntime, nor would we feel justified in giving you the exact quantities\nin the various grades, for we consider this information strictly\nconfidential. Then again a value which we would give you at this\ntime would not have applied in the past, and might not apply in the\nfuture.\nTe are glad, however, to advise that our different grades\nof Undark contain between one to 10 milligrams of radium element per\n100 grams of bulk. The average containing in the neighborhood of 3\nmilligrans of radium per 100 grams of bulk. We feel that this informa-\ntion should be sufficient to give you a pretty good insight as to the\namount of radium which girls, engaged in the application of this\nmaterial, handle.\nDue to our close contact with our customers we have\nnever felt it necessary to send out any printed precautions, as we have\nat frequent intervals discussed this matter with our clients, and given\nour ideas on the subject. We have, however, had occasion to write\nto E.R. Stitt, Surgenn General of the United States Navy, recently,"
