Crisis in Japan ‘on par with Chernobyl’
Japanese nuclear regulators said they raised the rating from 5 to 7 — the highest level on an international scale of nuclear accidents overseen by the International Atomic Energy Agency — after new assessments of radiation leaks from the Fukushima Dai-ichi plant since it was disabled by the March 11 tsunami.
The new ranking signifies a “major accident” that includes widespread effects on the environment and health, according to the Vienna-based IAEA. But Japanese officials played down any health effects and stressed the harm caused by Chernobyl still far outweighs that caused by the Fukushima plant.
