G CONSIDERATIONOFPURPOSEAND oOCRAP REMOVAL AT 3 nkRADLOACEIVE 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.
