results are not incluied. The exposures at the stations listed in Table 3.1 are possibly from initial gam radiation. Temperature effects on the film could have caused an increase in background density. ‘the presence of low-energy Gemma components in the residual field are indicated by the higher exposures measured by films exposed without NBS holders. The instrument- atian ani recovery rates were negliginile. 3.3 SHOT ZUMI See Tahles 3,2 and 3.3. Bight~inch steel-pipe stations were installed at Stations 210.23', 210.27’, 210.30', and 210.34’. The rate device at 210.27' became wedged in the station and failed to drop. The initial ganma readings vere obliterated by the residual radiation.°f The cap of 210.50' was broken by the shock, and the instruments fell Snetietely: DELETED. A third rate device at 210.34' without a dropping mechanism yielded only total exposure information. A mechanical drop device installed in a water-filled steel pipe at 210.23' fumetioned properly. All of the films that dropped read less then ir, since the initial exposure wes negligible. Sf, UlUIg vac 3.4 FLATSEAD See Yables 3.4 and 3.5. The disparity between the film and quartz- fiber exposures at Station 212.03 is not fully understood. At Station Ai2,.05 the 10-r thermal and blast exposures are the result of residual contamination from Shot Zimi. Film indicates sboutassis exposure, and quarte-fiber dosimeters indicate abo “mhe avitches in the
