Morse, Chiej Division of IndaitrUI Brglcna FOREWORD Probably no other source o energy which has been harnessed and brought within the range of control by man portends so much good or harm as does atomic energy. To industry it appears to offer potentialities for research and practical application on a scale never before available, while to m edicine it holds out op portunities fo r both research and therapeutic application which ,m ay have far reaching benefits on individual and public health. N o other m aterial or process has such inherent d an gers in its u se. That these health hazards can be controlled, has been clearly indicated by the Manhattan Dis trict Project. It h as been shown that control, however, is costly. In competitive industry, the ever-pjesem im portance o f reducing costs cannot be considered in the control o f this process. It rem ains fo r the industrial physician and hygiene engi neer to m ake this c lea r to their m anagem ents. . . . . The use o f atom ic energy in medicine likew ise p o ses a most serious problem. One has only to consider the very high incidence o f leukem ia am ong radiologists to realize that even m ore train in g and control proced u res a re v itally necessary to prevent radioactive isotopes from being an instrum ent o f destruction am ong the profession. . p t e Illin ois S u t e Departm ent o f P u b lic H ealth is read y to assist industry, the m edical p rofession and others in the v itally n ecessary m onitoring procedure which must he of sign al im portance i f radioactive m ate rials and atom ic energy are to he safely utilized.

ANNOUNCEMENTS SAFE USE OF RADIOACTIVE ISOTOPES One of the most insidious types of poisoning may develop from daily exposure to the radiations emanating from ra loacttve materials. The fact that these very hazardous materials can he safely utilized has been well demonstrated by me various Atomic Energy Commission laboratories, such as the Argonne Laboratory in Chicago. However, their safe use demand* the constant monitoring procedures utilized on these projects. Radioactive isotopes are being contemplated or are being used in industrial and medical research and controL Advice and counsel on the necessary precautions to protect personnel is one of the services available from this Division. 1 e Division is equipped with various radiation meters and other equipment to perform the necessary tests.
