Almost ten years after the disaster at the Fukushima Daiichi Nuclear Power Plant, researchers discovered a new kind of highly radioactive mineral particle in the fallout.
The plant suffered major damage from the magnitude 9.0 earthquake and tsunami that hit Japan on March 11, 2011. The wave disabled the emergency generators required to cool the reactors, causing a partial meltdown in one of the six reactor cores that eventually led to explosions, which released large amounts of radioactive material into the air. Fallout contaminated the surrounding area with high levels of radioactive uranium, strontium, lithium, sulfur and zirconium. Airborne small (micrometer-sized) particles were widely distributed, reaching as far as Tokyo.
