were immediately evacuated to the Base Camp, 25 kilometers to the
south. Film badges worn by personnel stationed at the north shelter,
however, showed no radiation exposure above the detectable level. It
was later discovered that the meter of the detector in the north
shelter had not retained its zero calibration setting, and radiation
at the north shelter had not reached levels high enough to result in
measurable exposures of the personnel who had been positioned there.
However, fallout activity was later detected in the north shelter
area, proof that part of the cloud did head in that direction. This
also explains why the monitoring device detected rising radiation
levels (1; 12).
