0021620 eine Observed values of the fraction of device contour ratio are given in Table 2. Before these data can be correlated to test some of the assumptions described by Eqs. 11 through 20, appropriate values for b, cy, G, D, and q for the various detonations are required along with generaliza- tions for obtaining appropriate values of these parameters for other detonation conditions. Also, the effect of fractionation and depth (or height) of burst on the contour ratios for land and seawater detonations is required for correlation of the date as well as for a general deter- mination of the scaling relations. ~ . 4.2 SELECTION OF VALUES OF b AND c FOR USE IN THE CONTOUR RATIO SCALING FUNCTION: The values of b and c, depend on the type of weapon that is detonated. In analyzing decontamination data obtained at weapons tests, values of b and c. are usually available from radiochemical analysis of cloud and (preferdbiy) fallout samples. Some data sources for data on b and C4 as well as other parameters for test devices and detonations ere summarized in Table 3. em DOE/NU |
