Slashdot: Whatever Happened to the 150,000 Tons of Radioactive Waste Stored Under the Atlantic Ocean?
Whatever Happened to the 150,000 Tons of Radioactive Waste Stored Under the Atlantic Ocean? Published on 2026-09-23T20:34:00Z More than 200,000 barrels of low-level radioactive waste were stored on the floor of the Atlantic Ocean between 1949 and 1982, reports ScienceAlert. Whatever happened to those barrels? Scientists have descended to the wreckage in a crewed submersible to investigate — and found many of the barrels corroded and degraded, their contents spilling across the seafloor. Surprisingly, this isn't necessarily a subversion of the original plan... The International Atomic Energy Agency recommends that low-level waste be disposed of in robust containment in isolation for at least a few hundred years — but back in the mid-20th century, the recommendations were a little different. The contemporaneous guidelines recommended that containers needed to reach the seafloor intact and remain sealed only long enough for the short-lived radionuclides to decay. After th...
