For the HARDTACK II (1958) series, the exposures to communities were all small and much less effort was devoted to estimating exposures. In general, most of the estimates of exposure to communities were based upon film badge data with no corrections applied. It is also important to note that during the earlier test series (prior to PLUMBBOB), no radiation surveys were made in some communities. In order to assess exposures for such communities, the TMCEFD constructed exposure isopleths and interpolated between these isopleths. The TMCEFD report (Sh59) itself contains data for the 300 communities aggregated by “Pre-PLUMBBOB,” “PLUMBBOB,“ “HARDTACK IT,“ and "Cumulative." Through the courtesy of the late Mr. Kosta Telegadas, we have access to the original compilations for the TMCEFD of estimated exposures by individual weapons tests. We have used these data to calculate population, or collective, estimated exposure. The population data were also taken from Sh59, wherein many population figures were listed as ranges over the total time period or were listed as "not available," “transient,“ or “variable.” Where ranges were provided, we used the higher number in our calculations of population exposure. Where the population was listed as "not available" or "transient," we have not included these locations in population exposure tabulations, but list them separately with the cumulative estimated exposures. Where the population was listed as "variable, " footnotes were frequently provided that contained sufficient information to calculate population exposures; if not, they were treated as locations of unknown population. 210
