The contaminated scrap metal on Bikini Atoll has been observed on islands
adjacent to test locations,
These adjacent islands which ‘lie along the
northera and southern rim of the Atoll islands have been sunjected to heavy
fission product fallout as well as blast, thermal, and prompe vadiacion
along with water waves,
The scrap metai on these islands consist of a
wide range of sizes.
Not ail metal pieces in a given areca are radioective.
Though ows i cens may be similar in anpecrence and located side by side
