survey found radiation levels to be meh lower than anticipated.
The
complete helicopter survey ammimaies confirmed the low contamination
levels encountered by the initial survey.
Several plausible reasons have
been advanced for the absence of heavy contamination.
‘The most reasonable
being that the water waves generated by the blast washed over the ‘land
areas and washed the early fallout away.
