The values of Dep(2)4n(2) and D, were taken from Reference 2 for U235 fission products which were o used to determine the rp, values in Section 4.3. The values of Dergcgt (1) are given in Table 11. “The rjcj values were taken from Table dnd the text of Section 4.2. The calculated values of the terrain factor, q, are summarized in Table 12. DOE/NWV The terrain factors calculated from fallout sample analytical data by means of Eq. 25 eontains sampling bias errors and errors in all the input terms to Eq. 25 as well as the true terrain factor (i.e. error in W, differences in the true fission yield factor per KT from 1.45 x 1023, error in @,, b, and the gross fractionation factors). Many of these errors are constant for a given shot. The sampling error is probably one of major contributors to errorswhich are not constant for a given shot. The average values of q and q/q in Table 12 were calculated on the basis that the sampling error was the major contributing factor where values of q greater than one were obtained. This assumes that, for the data used in Table 12, the sampling bias is most likely to be on the negative side - i.e. the sampling devices used would tend to ‘ 47
