C. WILLIAMS, Passed Assistant Surgeon, Office of Industrial Hygiene and Sanitation, United States Public Health Service. This report presents the observations made during a period of about a year and a half, from January, 1922, to July, 1923, on the physical condition of the persons employed during that time in the radium sec- tion of the United States Bureau of Standards, Washington, D. C. The reasons for making this study were twofold: (1) The necessity 0.30 for periodic supervision of the physical condition of persons engaged ADDITIONAL COPIES in the constant handling of radium, in order properly to safeguard OF THIS PUBLICATION MAY BE PROCURED FROM their health; (2) as a matter of scientific interest, to note the physical THE SUPERINTENDENT OF DOCUMENTS effects upon radium workers of continued exposure to radiation. GOVERNMENT PRINTING OFFICE WASHINGTON, D. c. Practically all the radium that is sold for medical or scientific pur- AT poses by manufacturers or commercial firms in the United States is 5 CENTS PER COPY 2 sent to the United States Bureau of Standards for measurement; thus the employees of the radium section of the Bureau of Standards daily handle radium in varying amounts up to 750 milligrams. The total amount that may be on hand at the Bureau of Standards at any one time varies from 0.5 gram to 4 grams. Radium bromide is the salt that is most frequently handled. It is not the purpose of this report to review the literature dealing with the physical effects on radium workers of continued exposure to radiation, but rather to record as a preliminary note the matters that have come under our observation. Acknowledgment is here made of the excellent cooperation and valuable assistance given during this study by Mr. W. H. Wadleigh, chief of the radium section. Through the courtesy of Dr. G. W. McCoy, director of the Hygienic Laboratory of the United States Public Health Service, all of the blood examina- tions were made by workers at the Hygienic Laboratory. It has been well known for several years that persons exposed to large amounts of radiation frequently experience harmful physical effects. Various general symptoms, such as headache, malaise, weakness, undue fatigue, unusual need of sleep, increased excitability, fretfulness, irritability, disordered menstruation, attacks of dizziness, 1 Reprint from the Public Health Reports, vol. 38, No. 51, Dec. 21, 1923, pp. 3007-3028. 3
