-~ 5 - Energy Commission installations. These operations will not be conducted in the expectation of possible hazard, but for scientific purposes and to keep the public informed on levels of radioactivity. Information will be provided by two monitoring networks, one consisting of 42 stations established by the U. S. Public Health Service and the other consisting of monitors at 11 Commission installations. are in Tables I and II. The locations of these monitoring stations The Public Health Service established its country-wide monitoring system in 1956 in ccnnection with the REDWING series of tests at the Commission's Eniwetok Proving Ground. Under a contract between the Public Health Service and the Commission the monitoring system will operate throughout the year. The Public Health Service monitoring stations will take daily radiation readings and collect filter samples of radto- activity and will forward these to a central collection office in Washington. The stations also will report data to the Health Officers of the states or territories in which the stations are located. They will be manned by trained technicians from state health departments, local universities and scientific institutions. Still another network in the United States gathers data which is used in a long range scientific study of the behavior of radioactive materials in the environment and their effect on man, This network consists of 46 U. S. Weather Bureau and 8 Atomic Energy Commission stations which collect fallout samples at selected locations throughout the nation and its territories. Measurements of Radioactivity Outside the U. S. Samples of airborne dust will be taken at approximately 7O localities throughout the world, in addition to the H6 U.S. stations, Soils also will be sampled on a world-wide basis, and Samples of other materials such as milk and cheese, field crops and human and animal bones will be taken for analysis of their Strontium-90 content. This program is part of the Commission's Project Sunshine, a study of the world-wide distribution and uptake of radio-active fission products, particularly strontium-90. - 30 Attachments 5158
