Operation Teapot

Fallout monitoring data for the United States and Canada during the spring of 1955 "Teapot" weapons test series are reported. In the continental United States individual station totals, extrapolated to January 1, 1956, range from 3.1 to 850 millicuries per square mile. Fallout in Canada and elsewhere is lower than in the United States. There are indications of continuing fallout in not greatly diminished amount for a short time after the close of the reporting period on May 20.
