the initial gemma exposure date in Table 5.16. Uncorrected exposure values are listed in the individual shet tables in Chapter 3. 2.3.2 Besidval Exposure Calibration. In ender to evaluste the initial gamma exposure, it was often necessary to estimate the resiéesl @uumen exposure. Some of the dosimeters associated with the quarts-fiber ts of Gevice and the mechanical dropping mechanion yieléel measuremen yesidual gues reiistion. Over the limited areas of interest (300 feet ures aid or less) the fallout pattern was generally continuous and expos not vary greatly, hence it was possible te estimate the exposures at stations where no specific data were availabie. These estinates were consistent both with calculations based on measurenents of yesifival gaume intensity mate at the time of station instrument recovery, and wth ct 2.2.
