Fukushima just can’t catch a break. Officials at Japan’s Fukushima Daiichi nuclear plant, which was damaged in March's tsunami, detected radioactive xenon. The gas, which is involved in fission, may be a sign that the reactor is leaking. As a precaution, officials are injecting boric acid using a cooling pipe. The reactor’s temperature, however, has not increased, leading officials to think that this is not a major problem.
