This is work regarding nuclear weapons testing is based on material created for the Bureau of Ships in 1960 and 1961. It presents the findings of experimental investigations of the effectiveness and efficiency of decontamination procedures using synthetic fallout and the operational evaluations of the data.
It includes empirical equations developed from correlations of fallout data from nuclear weapons testing for estimating the composition of fallout from detonations on land or at sea as a function of weapon yield and type, height of burst, and other parameters. The compositions are given in terms of the two contour-ratios defined in Part I of this study, namely, the mass contour ratio and the fraction of device contour ratio.
The effect of weapon yield, downwind distance from ground zero, induced activities, fraction of fission yield, height of burst, fractionation, terrain features, instrument response, extraneous debris, and meteorology on the values of the two contour ratios is discussed.
The objective of the report is to discuss the major parameters from nuclear weapons testing that can influence the radiochemistry and chemical composition of fallout and to develop empirical contour ratio scaling relationships to estimate realistic fallout compositions. It is also the goal of paper to present information that will prove useful in preparing synthetic fallout.
The work is based on reports from the Marshall Islands to help the government determine the development of methods for estimating the composition of contaminated systems as a result of nuclear fallout. It was registered through the US Atomic Energy Commission and created by the U.S. Navy Radiological Defense Laboratory in San Francisco.
