[...] Nuclear experts noted that other lethal radioactive isotopes would also be released in such a fire, but that the focus is on cesium-137 because it easily volatilizes and spreads pervasively, as it did during the Chernobyl accident and again after the disaster at Fukushima Daiichi last year.
With a half-life of 30 years, it gives off penetrating radiation as it decays and can remain dangerous for hundreds of years. Once in the environment, it mimics potassium as it accumulates in the food chain; when it enters the human body, about 75 percent lodges in muscle tissue, including the heart. [...]
