The mean specific-activity of Bikini spoil totals less than 1074 Ci/ton for all radionuclides and thus falls below the former | so-called de minimis level of 1073 Ci per metric ton, a non-official level now, but However, one at that might present, well there is be considered no legal acceptable standard and scientifically. the matter is under international study (29N).
