Report concerning the protection offered against radioactive fallout offered by two types of structures at the Nevada Test Site. Differences between above ground and underground structures are measured and compared to data taken from actual fallout conditions.

From Introduction: "As a result of research accomplished during Operation BREN in 1962, it has been proposed that a monoenergetic point neutron source be constructed and operated on the same tower. The field experiment which would be conducted at this time has been designated as Operation HENRE (High Energy Neutron Reactions Experiment)."

Introduction: The U.S. Geological Survey is appraising the possibility, however slight, that the ground water beneath the Nevada Test Site, possibly contaminated by nuclear detonations, may carry radioactive fission products to places where they may constitute a public hazard.

From summary: Site investigations were conducted at two locations, the sites of the DUGOUT and CHARLIE events, at the Nevada Test Site for the purpose of evaluating the dynamic in situ technique as a means of determining the boundaries of craters produced by explosive detonations.

From introduction: The general objectives of this Geological Survey were to study the geologic and geophysical studies of the effects of underground nuclear explosions under Rainier Mesa.

From introduction: This report is a summary of the detailed geologic and engineering information that is available on three sites for underground explosions on the Nevada Test Site.

From introduction: The papers comprising the various parts of this report contain the preliminary results of the U. S. Geological Survey investigations in the Ul2e.05 tunnel at the Atomic Energy Commission's Nevada Test Site, Nye County, Nevada (fig. 1). Reports on electrical resistivity, natural radioactivity, and heat required to raise the rocks to 100C will be issued later. A preliminary report on the geologic effects of the Blanca event is being prepared.

This is a airborne reconnaissance report of the Williams Quadrangle in Arizona.

This is an airborne reconnaissance report on several quadrangles in Arizona, California, and Nevada.

Single record and averaged record data listings for the Kingman quadrangle in Arizona, California, and Nevada, taken during a reconnaissance survey.

From Introduction: "The Vya 2º quadrangle (Fig. 1), in northwestern Nevada and small portions of California and Oregon, was evaluated to identify geologic environments and to delineate areas that have characteristics favorable for uranium deposits. Reconnaissance sampling in the Vya Quadrangle began in 1978, but final evaluation of the uranium favorability of the quadrangle was began in 1978, but final evaluation of the uranium favorability of the quadrangle was begun in June 1980."

The following report summarizes the results of a brief geological examination made by the Geological Survey of the small uranium deposit in the Majuba Hill mine, Pershing County, Nevada.

The following report provides a geological map of sections of the Thirsty Canyon South East quadrangle of Nye County, Nevada.

Appendices containing data on uranium availability in the Vya Quadrangle to accompany a report on U.S. uranium resources in Nevada, Oregon, and California.

This report briefly describes the geological data of the U12b.10 tunnel at the Nevada Test Site.

The following report presents the lithologic log of the description of the tuff penetrated by the U12g.06-U1 core drill hole located at the end of the U12g main tunnel at the Area 12, Nevada Test Site.

The following report summarizes the geological and geophysical studies made on the rocks of the Midi Mist site in the Area-12 tunnel complex of the Nevada Test Site. The data was needed to determine whether the rock met the technical criteria of the nuclear experiment.

The following report is the second volume in a series of reports documenting airborne gamma-ray spectrometer and magnetometer survey results. The data on this report focuses on the Las Vegas quadrangle.

The following report is the second volume in a series of reports documenting airborne gamma-ray spectrometer and magnetometer survey results. The data on this report focuses on the Kingman quadrangle.
