Abstract

This report predicts the radiological contamination that may result from fission bombs detonated near the surface of the earth and underground. The radiation received is primarily a result of the initial radiation from the early fission products and fallout of radioactive material from the high cloud. The distribution of the fallout is determined by constructing a mathematical model and adjusting the parameters of the model to fit actual Jangle data. The model is then scaled up to larger weapons by scaling these parameters in conformity with existing formulations of nuclear-explosion cloud dynamics. The initial radiation is calculated in a straightforward manner. The resulting dose and dose-rate contours are given, as are the areas enclosed by given contours. It is concluded that the base surge at the Jangle underground nuclear explosion did not contain an appreciable amount of radioactive material, and this will probably also be true for operational weapons except at very great explosion depths. The cratering action of explosives is discussed, and it is found that atomic bombs exploded near the earth surface should give crater radii which sale as the one-sixth power of the energy release rather than the one-third power scaling applicable to high explosives.

Predicted scaling of radiological effects. Project 2. 0 (of) Operation JANGLE

Technical Report Schorr, M; Gilfillan, E

The radiologicl contamination which may result from fission bombs detonated near the surface of the earth and underground is predicted. The radiation received is primarily a result of the initial radiation from the early fission products and fall-out of radioactive material from the high cloud. The distribution of the fall-out is determined by constructing a mathematical model and adjusting the parameters of the model to fit actual JANGLE data. The model is then scaled up to larger weapons by scaling these parameters in conformity with existing formulations of explosion cloud dynamics. The initial radiation is calculated in a straightforward manner.more »« less

Fallout studies. Project 2. 5. 1 (of) Operation Teapot

Technical Report Bouton, E; Hardin, L; Schumchyk, M

The purpose of the project was to obtain the data required to close the 1 r/hr at H + 1 hr dose rate contour lines and in so doing obtain information concerning the role of the base surge as a primary carrier of activity, radiation intensities in areas contaminated by fallout, base surge, and in the crater lip region, time of arrival of activity at locations within 2 to 5 miles of ground zero, depth of burial of activity in the crater and on the lip, and air-to-ground correlation factors developed during aerial survey of contaminated areas.

SOME HE TESTS AND OBSERVATIONS ON CRATERS AND BASE SURGES

Technical Report Campbell, D

Ten HE shots were conducted in the upper Yucca Flat and Frenchman Flat areas in order to obtain data for predictions concerning the phenomena to be studied during Jangle Operation. The HE data indicated that for the Jangle surface burst a base surge would be unlikely, and the maximum altitude of the cloud would be approximately 12,000 ft. The data also indicated that the Jangle underground burst would have considerable throw-out at the base of plume, and the base surge, if any, would be small. Since the crater diameter is a readily scaled parameter for underground TNT explosions, then themore »« less
OPERATION JANGLE. Project 4.1: AERIAL TECHNICAL PHOTOGRAPHY

Technical Report Crawford, F

The methods and apparatus used in the sequence aerial photography of the physical phenomena of Operation- Jangle are given in detail. Three C-47 type planes with multiple camera installations orbited over the target; each plane had 5 aerial stlll cameras, 3 35mm cameras, 1 l6mm motion picture camera, and 1 35mm high-speed camera. Only 2 cameras failed completely during operation. The phenomena recorded included shock waves, base surge, cloud formation and initial fireball.
