It is the duty of the health physicist to evaluate and control any potential hazard in the use of nuclear energy. The health physicist understands the effects of radiation on human tissues and plants. He keeps a constant check on radiation levels in installations where radioactivity is used; he foresees emergencies that might arise; he eliminates unsafe practices; and he assures that personnel working in nuclear energy fields are free from related hazards. The health physicist is a key figure in making the nuclear energy industry one of the safest in the world. Another profession that spans the sciences is that of the technical writer or editor. In a laboratory he translates the notebooks of the scientist into reports. In an editorial office he edits manuscripts for publication. On a newspaper staff he translates scientific findings into articles for the public. It is difficult, undesirable, and usually impossible, for a scientist to confine himself to his own field because all sciences affect one another. A chemist may use the tools of the physicist and become a physical chemist; a physicist may go in the other direction and become a chemical physicist. It is not uncommon for a chemical engineer to find himself doing the work of an instrument engineer, or the mechanical engineer to find himself doing the work of an electrical engineer, or both of them doing the work of a nuclear engineer. The physicist, the chemist, the physician, and the engineer who once thought that outer space was the exclusive domain of the astronomer now find themselves solving reentry problems for missiles, stirring up rocket fuels, testing the effect of weightlessness on the body, and examining diagrams for space craft. Perhaps the botanist who today is totally concerned with the flora of earth will tomorrow find himself fingering a bit of fungus from Mars. Location of the Atomic Scientist In the rapidly changing world, each year finds the scientist increasingly important. He is needed to maintain and improve fast-changing technology, to combat disease, to develop natural and man-made resources, to improve food sources and production, and, in general, to work for the betterment of mankind. The graduate scientist and the engineer will find jobs waiting and will be able to choose, to some extent, the sort of work they wish to do and where they wish to do it. It is impossible to list all types of organizations open to science graduates, but it is relatively simple to divide them into general groups. The United States Government
