Fukuchima reaches Level 7 on INES scale

The ‘level 7’  is not official yet, but I don’t see how they can keep it at 6 given the measured radioactive.   Example:

Regarding the Cesium-137 levels of 163,000 becquerels per kilogram of soil in Iitate, 40 km from the Fukuchima Daiichi NNP:   Tetsuji Imanaka, an associate professor of nuclear engineering at the Kyoto University Research Reactor Institute, [calculated that] if the Iitate figure was converted to one square meter, the figure would be 3.26 million becquerels.

3,260,000 Bq / square meter  Cs-137 ! 40 kilometers from F. Daiichi NNP !

  • After the Chernobyl accident, residents who lived in regions with radioactive Cesium levels of 550,000 Becquerels or more per square meter faced MANDATORY evacuation.

Using the released figures to calculate the amount of discharge between 6 a.m. March 12 and midnight Wednesday March 23, results in figures between 30,000 and 110,000 terabecquerels.

The Fukushima accident is already at a level 6, which is defined as having a radiation discharge of several thousands to several tens of thousands of terabecquerels.

The INES defines a level 7 major accident (such as Chernobyl): one in which radiation of more than several tens of thousands of terabecquerels is released. Not per square meter, of course, but as a total from the spewing plant(s).

1 terabecquerel = 1 trillion Bq = 1,000,000,000,000 Bq   (Tera is a prefix meaning 1 trillion.)

“Between 30,000 and 110,000 terabecquerels”. seems rather clearly “more than tens of thousands terrabecquerels” to me.  Meanwhile we’re several days later and the radiation leaking continues.  Is it over yet?  What’s the latest?  Here, (from Mar. 26, 2011, 8:24 AM JPN-time):  “The process of cooling the facilities has seen limited progress. Government spokesman Yukio Edano told the press, “the current situation is that we are preventing it from worsening.””
