Abstract: Crater data from numerous high-explosive
from fewer nuclear explosive
(NE)
(HE)
experiments and
tests are used to develop an
empirically based procedure for predicting crater dimensions from
nuclear explosions in various geologic media. The HE crater data are
used to rank the cratering efficiency of various geologies. NE crater
data from dry soil at the Nevada Test Site and from saturated coral at
Eniwetok and Bikini atolls are used to relate NE and HE cratering
efficiency. Crater shapes from explosive and impact craters are
examined to provide a basis for estimating crater radius and depth in a
given geology once the crater volume is known. Best estimates of the
crater volume and dimensions are presented along with an estimated
range of uncertainty.;

Abstract: Results are reported from the radiological analysis of
environmental samples collected in the Marshall Islands during 1974
through 1976. Most of the samples were collected on or near the Bikini
Atoll and included plants, soil, fish, catchment water, and sediments,
with emphasis on local marine and terrestrial food items. Data are
presented from ..gamma.. spectral analysis and the content of /sup
90/Sr and transuranic elements in the samples.;
