The microscopic particles unleashed by the plant’s explosions are also a potential environmental and health concern

On March 14 and 15, 2011, explosions unleashed invisible radioactive plumes from the Fukushima Daiichi Nuclear Power Plant, crippled three days earlier when the strongest recorded earthquake in Japan’s history triggered a massive tsunami. As the plumes drifted over the neighboring countryside, their contents—including radioactive cesium, a by-product of the plant’s fission reactions—fell to the ground and over the ocean.
What no one knew or expected was the fallout also contained bacteria-size glassy beads, with concentrations of radioactive cesium that were far higher than those in similar-size motes of tainted dust or dirt.
