for NTS and global fallout, they have been able to determine the amounts of NTS-derived 13765 in soil. They (Be82) then calculated the short-lived fission products that would have accompanied the 1376, from NTS and the resulting infinite exposure. A comparison of their results and the TMCEFD results is shown in Table 7 for all communities where data from both sources are available. The two sets of results, based upon independent methods, agree well. The TMCEFD did not calculate estimated exposures at distances as far away as Salt Lake City, Utah, and fallout patterns were not plotted to such distances, in general. Data in Be82 indicate that the cumulative infinite exposure at Salt Lake City might have been 1.2 R and the cumulative population infinite exposure might have been 220,000 person-R; the cumulative estimated exposure and the cumulative population estimated exposure would be approximately half of these amounts. The latter is larger than the total population estimated exposure shown in Table 5 for all of the closer in communities that are considered to be in the “high fallout” region. Because the raw data that served as input to calculations in this paper have not been generally available to the scientific community, we have prepared a companion report (An82) that contains these data and a reproduction of the TMCEFD report.
