Friday, Japan’s spokesman for the nuclear safety agency, Ryohei Shiomi, confirmed the severity rating of the Japan’s nuclear crisis from Level 4 to Level 5, putting it on a par with the 1979 Three Mile Island catastrophe in the United States. The Fukushima Dai-ichi nuclear crisis had been raised on the seven-level International Nuclear Event Scale.
The characteristics of a Level 5 emergency are severe damage to a reactor core, release of huge quantities of emission with a high possibility of “significant” public exposure or several deaths from radiation.
A partial meltdown at Three Mile Island in Pennsylvania was also ranked a Level 5.
The Chernobyl disaster in the Ukraine in 1986, which killed at least 31 people with radiation sickness, brought long-term cancer rates, and spew out radiation for hundreds of miles, was ranked a Level 7. Agencies
