Abstract.
An intensive radiological survey of the
islands of Bikini Atoll was conducted in May 1967 for the
purpose of determining the levels and components of the
Oo
external gamma radiation fields in this former nuclear
weapons testing area.
..
Total exposure rates were found to
wt em
vary considerably from site to site and island to island
.
with levels measured over soil ranging from less than 10
pxr/hr to over 500 pr/hr.
