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. © .-#.
