eign. mobile monitoring teams on call to go to any locality to assist if needed or to travel to areas outside the 17 zones. Four additional monitoring programs are also in operation. One of these projects is primarily of research nature yet provides radia- tion monitoring data out to 160 miles or more from the test site. A second program is a unique system of telemetering, whereby instruments are placed in about 30 communities around the test site and connected to commercial telephone wires. The operator sits at the control point and, by placing a normal telephone call, receives back signals that are translated in a matter of seconds into gamma radiation dose rates. A third project consists of automatic instruments located in another 15 communities that permanently record the gamma dose rates continuously from the begiming to the end of the test series. A fourth program con- sists of aerial surveys with special gamma detection instruments. Extending outward from the Test Site across the country are 38 U. S. Public Health Service monitoring stations established in coopera~ tion with the Atomic Energy Commission, and 11 AEC installations (See Tables 6 and 7). In addition, through the cooperation of the U. S. Weather Bureau 93 stations in the United States make gummed paper collections of fallout (Table 7). These gummed paper collections are also made world-wide at 73 other locations by arrangement with the Department of State, U. S. Weather Bureau, U. S. Air Force and Navy (Table 9). ~ 29 - 7 ok .
