SALT LAKE CITY -- Japan's nuclear safety agency raised the severity of its nuclear crisis at the Fukushima Dai'ichi power plant to the highest level, putting it on par with the nuclear disaster in Chernobyl.

An agency spokesperson says the cumulative levels of radiation released lead to the decision to raise the level to seven - which is the worst on an international scale.

It had been at five, which is similar to the Three Mile Island incident in the U.S.

While we are hearing that this nuclear crisis is bad, what exactly does that mean?

The fact the level has been raised doesn't mean the situation has become worse -- rather, this change reflects a more accurate and fuller reading of radiation levels.

KSL's Andrew Adams has been looking into just what this level 7 designation means. Watch the video above for a Q&A about the nuclear crisis and its repercussions.
