Analysis of Operation TUMBLER-SNAPPER Nuclear Test EASY Radiological and Meteorological Data

摘要

This report describes the Weather Service Nuclear Support Office (WSNSO) analyses of the radiological and meteorological data collected for the EASY nuclear test of Operation TUMBLER-SNAPPER. Inconsistencies in the radiological data and their resolution are discussed. The methods of normalizing the radiological data to a standard time, of converting the aerial radiological data to equivalent ground-level values, and of estimating fallout arrival times are presented. The meteorological situation on the event day and a few days following is described. A comparison of the WSNSO fallout analysis with an analysis performed during the 1950s is presented. The radiological data used to derive the WSNSO fallout pattern are tabulated in an appendix. 7 refs., 22 figs., 5 tabs. (ERA citation 11:017218)
