APPENDIX SAFETY PROCEDURES AT THE NUCLEAR TESTING SITES NEVADA TEST SITE Generali The safety programs and procedures described below were in use during atmospheric tests at the Nevada Test Site. Since the signing of the Limited Test Ban Treaty essentially all of these programs remain in effect, but generally at a reduced level, thus providing for a continuous monitoring of persons ! and the environment for documentary purposes, and assurance of a nucleus of well trained personnel (fig. 9). The health and safety of persons was the major consideration in the original selection of the Nevada Test Site and this continues to be of paramount importance during the conduct of nuclear tests. An exhaustive search was made before the Nevada site was selected as the most suitable one. It originally contained 600 square miles (later expanded to about : j 1,290 square miles) adjacent to the U.S. Air Force Gunnery j | : Range of 4,000 square miles. For purposes of general safety, as well as security, the Test Site was and continues to be closed to the public. Safety of personnel was and is further assured by aerial and surface surveys made prior to each detonation to determine that no one had wandered into the area. Beyond these controlled areas are wide expanses of sparsely populated land, providing optimim conditions for maintenance of safety. Although the area is quite sparsely populated the individual resident has been given full consideration. Radiation monitors have been present during times of testing and there have been occasions when residents have been relocated for a day or so to insure fully their safety. Persons relocated have received financial remuneration for such movements. There have also been occasions when persons have been asked { to remain indoors for a few hours to reduce the radiation dose, although the out-of-door exposure would have been far from hazardous. Before each and every nuclear detonation at the Nevada Test Site, an Advisory Panel of experts weighed carefully all of the factors that insured safety. Loory ae Coe Su On the panel were repre- 3d
