Under.a contract between the Public Health Service and the Commission, the monitoring system will operate throughout the series and for some weeks thereafter, The primary purposes of the system are to give state and local health departments more experience in studying fallout and normal background radiation levels, and to obtain daily records of radio- activity. i The stations are manned by trained technicians from state health departments, local universities and scientific institutions, Measurements of Radioactivity Outside the U.S. Dust samples are collected at 73 stations outside of the con- tinental United States and extending around the world. locations are: Their Addis Ababa, Ethiopia; Anchorage, Alaska; Bangkok, Siam; Beirut, Lebanon; Belem, Brazil; Bermuda; Buenos Aires, Argentina; Canal Zone; Canton Island; Churchill, Manitoba, Canada; Clarke AFB, Philippines; Colombo, Ceylon; Dakar, French West Africa; Deep River, Ottawa, Ontario, Canada; Dhahran, Saudi Arabia; Durban Natal, South Africa; Edmonton, Alberta, Canada; Fairbanks, Alaska; French Frigate Shoals; Goose Bay, Labrador; Guam; Hilo, Hawaii; Hiroshima, Japan; Honolulu, Hawaii; Iwo Jima; Johnson Island; Juneau, Alaska; Keflavik, Iceland; Koror; Kwajalein; La Paz, Bolivia; Lagens, Azores; Lagos, Nigeria; Leopoldville, Belgian Congo; Lihue; Lima, Perv; Melbourne, Australia; Mexico City, Mexico; Midway Island; Milan, Italy; Misawa, Japan; Moncton, New Brunswick, Canada; Monrovia, Liberia; Montreal, Quebec, Canada; Moosoonee, Ontario, Canada}; Nagasaki, Japan; Nairobi, Kenya, East Africa; Nome, Alaska; North Bay, Ontario, Canada; Nownea, New Caledonia; Oslo, Norway; Ponape; Prestwick, Scotland; Pretoria, South Africa; Quito, Ecuador; Regina, Saskatchewan, Canada; Rhein Main, Germany; San Jose, Costa Rica; San Juan, Puerto Rico; Sao Paulo, Brazil; Seven Islands, Quebec, Canada; Sidi Slimane, French Morocco; Singapore; Stephenville, Newfoundland; Sydney, Australia; Tai Pei, Formosa; Thule, Greenland; Tokyo Air Base, Japan; Truk; Wake Island; Wellington, New Zealand; Whéelus AFB, Tripoli; Winnipeg, Manitoba, Canada; Yap. Soils also are sampled on a world-wide basis, and samples of other materials such as milk and cheese, field crops, and human and animal bones are 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 strontium-90,. Fallout Computers Two electronic computers designed to provide a very rapid forecast of nearby radioactive fallout are being used for the first time in continental atomic tests during Operation Plumbbob. Both machines furnish extremely fast information to the Test Organization on just where and in what amounts there may be fallout L= —a' Ie oe r 4 ie - 59 - qf \
