But in addition to tritium, more dangerous isotopes with longer radioactive lifetimes, such as ruthenium, cobalt, strontium, and plutonium, sometimes slip through the ALPS process, something TEPCO only acknowledged in 2018. The company now says these additional nuclides are present in 71% of the tanks. "These radioactive isotopes behave differently than tritium in the ocean and are more readily incorporated into marine b...
