Pagination or Media Count:
Low-pressure air blast was measured for Project Danny Boy out to distances of 240 kilometers in order, primarily, to determine the attenuation caused by the hard rock environment of the shot and to compare results from both nuclear and HE shots in other media. Nine microbarograph stations were operated. Communications problems and strong local winds reduced the number of signal correlation points. Air-blast pressures, both close-in and far-out, were smaller than were expected, based on past experience with underground HE shots. Distant off-site recordings indicated that blast pressure amplitudes from the Danny Boy shot averaged only 14 percent as large as would have been received from a shot having the same nuclear yield, free-air-burst.
