The radioactive particles released in the course of the Fukushima nuclear emergency were mostly iodine 131 and cesium 137; radioactive iodine, which has a half-life of 8 days, is taken up by the thyroid gland, and cesium, with a half-life of 30 years, is deposited in the muscles. Plutonium leaks were also detected. In the Chernobyl accident, by contrast, due to the explosion of one of the nuclear reactors, large amounts of strontium 90 and some of the nuclear fuel (uranium) and its decay product (plutonium) were also released.
