Project Buggy Gamma Fallout Field
Abstract
Project Buggy was the first nuclear row cratering detonation executed as part of the Plowshare Program for developing nuclear excavation techniques. Five nuclear explosives, each with a yield of 1.1 kt, were detonated simultaneously at 0904:00.111 PST, 12 March 1968. The explosives were detonated at depths of 135 feet and were spaced 150 feet apart. The experiment took place on Chukar Mesa, Area 30, Nevada Test Site, in a dry, complex basalt formation. The objectives of this phase of the Buggy Event were as follows: (1) to provide ground level gamma fallout field measurements for estimating the total gamma radioactivity vented and deposited in early fallout, (2) to provide fallout field contours from this test event for use in normalizing fallout prediction models, and (3) to determine whether the amount of radioactivity deposited in early fallout from a nuclear row charge is significantly different from that resulting from a single cratering detonation. The gamma radiation early fallout field of the Buggy Event was measured and documented. The radioactive decay of the field with time also was followed. Isoexposure rate contour maps of the fallout field are presented. Analysis of the information collected shows that approximately 3.3% of the gamma-emitting radioactive material produced was deposited beyond the area of continuous ejecta in the fallout field.
