ABS>Operation Teapot, in the spring of 1955, consisted of 14 atomic detonations at the Nevada Test Site. Meteorological trajectories were computed for the resulting radioactive debris and related to the fallout observed by the gummed film network of 87 stations in the continental United States, twelve stations in Canada, and six stations elsewhere in North America. Maps showing daily fallout data for the period February 18--May 20, 1956 are appended. A series of special film observations near Chicago inposed in vertical and inverted positions averaged about 40 percent of the activity on a regular horizontal film. On days with precipitation, the values were 4 percent on vertical films and 1 percent on the inverted films. A radioautograph of individual raindrops during a period when rainout was occurring indicated about three drops in a hundred were radioactive. The radioactive drops contained both particulate and dissolved radioactivily. (auth)
