UCLA scientific personnel obtain soil and plant samples and hunt and trap wildlife and rodents in fallout areas from the Test Site out to about 160 miles, They also study the distribution of fallout particles of different sizes with the objective of provid- ing information which can be used in the prediction, of fallout patterns, If fallout is recorded in areas Within California, Utah or Nevada where crops are grown, samples of soil, forage crops, vegetables and milk will be collected to learn more about the biological availability of fission products, Monitoring in Continental United States Outside of the area within about 200 miles of the Test Site, monitoring activities are conducted in cooperation with the U, S. Weather Bureau, the U. S. Public Health Service, and 11 Atomic Energy Commission installations. These operations are not conducted in the expectation of possible hazard, but for scientific purposes and to keep the public informed pn levels of radioactivity. = As in past test series, a network of U. S. Weather Bureau stations collects dust samples, The stations expose sheets of film covered with adhesive outdoors on a tray each for 24 hours, and then mail them to the Commission's Health and Safety Laboratory in New York. There, the samples are reduced to ashes and the radioactivity measured with extremely sensitive instruments, Ninety-three Weather Bureau sampling stations are in operation during Operation Plumbbob, Their locations are: Abilene, Texas; Albany, New York; Albuquerque, New Mexico; Alpena, Michigan; Amarillo, Texas; Atlanta, Georgia; Bakersfield, California; Baltimore, Maryland; Billings, Montana: 3in-'amton, New York; Bishop, California; Boise, Idaho; Boston, Massachusetts; Buffalo, New York; Caribou, Maine; Casper, Wyoming; Charleston, South Carolina; Cheyenne, Wyoming; Chicago, Illinois; Cleveiand, Ohio; Colorado Springs, Colorado; Concord, New Hampshire; Corpus Christi, Texas; Concordia, Kansas; Dallas, Texas; Del Rio, Texas; Denver, Coloredo; Des Moines, Iowa; Detroit, Michigan; Elko, Nevada; Ely, Nevada; Eureka, California; Fargo, North Dakota; Flagstaff, Arizona; Fort Smith, Arkansas; Fresno, California; Goodland, Kansas; Grand Junction, Colorado; Grand Rapids, Michigan; Green Bay, Wisconsin; Hatteras, North Carolina; Helena, Montana; Huron, South Dakota; Jackson, Mississippi; Jacksonville, Florida; Kalispell, Montana; Knoxville, Tennessee; Tas Vegas, Nevada; Los Angeles, California; Louisville, Kentucky; Lynchburg, Virginia; Marquette, Michigan; Medford, Oregon; Memphis, Tennessee; Miami, Florida; Milford, Utah; Milwaukee, Wisconsin; Minneapolis, Minnesota; Mobile, Alabama; Montgomery, Alabama; New Haven, Connecticut; -New Orleans, Louisiana; New York (La Guardia), New York; Philadelphia, Pennsylvania; Phoenix, Arizona; Pittsburgh, Pennsylvania; Pocatello, Idaho; Port Arthur, Texas; Portland, Oregon; Prescott, Arizona; 1 gn 7. se Nes
