To ~ndustry it appean to ofifter. potentialities for .research and practical :f.pplication on a scale never before available, while to medicine ,it holds out op- portunities for botb research and therapeutic application which ,may have far reachin~ benefits on mdividual '~d public health. '. .... . No other material or process has a~"h inh~rent dangers in its use. Tbh'at these health hazards can be controlled. has. been clearly indicated by the Manhattan Dis- t:rict Project. It has been Shown that control, however, is costly. In competitive industry. the everoPFn't importance of reducing costs cannot be considered in lhe control of this process. It remains for the industrial phy.ician and hygiene ensi, neer to make this clear to thefr manasements. " '. . The use of atomic energy in medicine likewise P08el\ a mo~t serious problem. One has only to consider the very hiGh incidence of leukemia among radiologists to reali:f: !hat even more ulining and control procedures are vitally neCe5ury to prevent radioactive isotopes from ~ing an instrument of destruction among the profesllion. The Ulinois Slale Department of Public Health is rea.dy to assist industry, the medical profession and others in the vitally necessary monitoring procedure which must he of signal importance if radioactive materials and atomic energy are to be safely utilized.
