Estimating Safety Probabilities from Fallout Forecasts for Nevada Test Site

Abstract: "Available data on wind persistence and wind forecasting capability have been applied in estimating the probability of a fallout pattern shifting from an uninhabited safe sector into a populated region. Safety probability is computed from win variability, forecasting accuracy, initial height and particle size of radioactivity landing at a point in the predicted fallout pattern, predicted wind speed, length of forecast period, and safe-sector angular width."

A Study of Nevada Test Site Wind Variability (open access)

A Study of Nevada Test Site Wind Variability

Abstract: "Wind observations collected at Yucca Flat since 1951 are analyzed for timewise variability. Variability functions of altitude, season, wind speed, and vector wind are described. Derived variability parameters are incorporated into calculations of fallout safety probability for NTS operations."

Comparison of Fallout Doses from Nevada Tests (Revised) (open access)

Comparison of Fallout Doses from Nevada Tests (Revised)

From abstract: Many residents of the Nevada area carried film badge radiation dosimeters during Operation Plumbbob in 1957. Badge readings in specific localities appear to follow the logarithmic-normal distribution.

High-Explosive Ditching from Linear Charges (open access)

High-Explosive Ditching from Linear Charges

Abstract: "Weights of linear high-explosive charges fired on the Yucca Lake playa of the Nevada Test Site varied from 0.23 to 42.7 pounds per foot. Crater and ditch dimensions and volumes resulting from these shots, fired during the fall of 1959 and spring of 1960, are presented here as a function of charge burst depths. Scaling relationships determined are as expected; i.e., square-root scaling of linear-charge weight per foot for ditch width and depth and a direct linear-charge weight relationship to ditch volume are obtained. Permanent ground surface displacement varies as the -3.22 power of the scaled distance from the charge. Detonation effects, charge shape effects, ditch erosion, and ditch cross sections are discussed. The appendixes present Toboggan data, results of soil investigation, and mathematical treatment given the data."

Salton Sea Meteorological Instrumentation Test Series, Salton Sea, California, Conducted in September 1959 (open access)

Salton Sea Meteorological Instrumentation Test Series, Salton Sea, California, Conducted in September 1959

Abstract: "This report discusses tests conducted to determine the accuracy of meteorological equipment which is used to gather upper air data. Equipment tested was the GMD-2, SMD-1A, GMD-1B, and the WBRT-57. A four-station phototheodolite network was used as a standard for point-in-space determinations."

20-ton HE Cratering Experiments in Desert Alluvium: Final Report, May 1962

From abstract and summary: Project Stagecoach consisted of the detonation of three 40,000-pound charges. Blocks of cast TNT were stacked to resemble a sphere and, the whole center-detonated.

Ejecta from Single-Charge Cratering Explosions: Volume 1 (open access)

Ejecta from Single-Charge Cratering Explosions: Volume 1

"Eight high-explosive charges weighing 8 to 1000 pounds were detonated in playa. Each event included 24 to 40 locations of tracer material in the expected crater region. The objective was to obtain data relating the origin of crater ejecta to its depositional location. Resulting data are presented for craters, ejecta areal densities, crater and ejecta mass quantities, tracer dispersion, and an empirical prediction model."
