 The decontamination after the Goiânia accident in Brazil 1987 and the possibility of a "dirty bomb" with Co-60, which has similarities with the environment that one would be faced with after a nuclear yielding cobalt bomb's fallout had settled, has prompted the invention of "Sequestration Coatings" and cheap liquid phase sorbents for Co-60 that would further aid in decontamination, including that of water.In 2015, a page from an apparent Russian nuclear-armed torpedo design was accidentally or deliberately leaked.The design was titled "Oceanic Multipurpose System Status-6".
