Fallout Patterns from Operation HARDTACK, Phase 2

Abstract

The Hardtack, Phase II, nuclear test operation differed from previous series in the great number of nuclear and safety devices detonated within a fairly brief period, in the very low yields of many of the detonations, and in the variety of burst conditions. Basic information on the various bursts is summarized on the inside of the front cover. Orientation maps of the Nevada Test Site region, and of the Nevada Test Site itself are shown on the inside of the back cover. As far as public safety is concerned, radiation from Hardtack, Phase II, was even less important than that from most previous Nevada test operations. However, since low levels of activity are fairly difficult to detect, the documentation of such fallout that did occur was comparatively difficult. The radiation from passing airborne radioactive clouds was relatively more important than in previous test series because of the many low nuclear cloud heights. There were also problems concerning decay rates and the arrival times of the fallout. The purpose of this report is to present and discuss the fallout patterns from Operation Hardtack, Phase II. Although there are many uncertainties in the analysis of the fallout data, careful consideration has been given to all available monitoring and wind information in an attempt to depict as well as possible the actual fallout patterns.
