Fukushima Radiation Emissions

Blogger Ex-SKF has a very interesting post people should read. I'm going to excerpt some of it. Use the link to read the full article:
1 Billion Becquerels Per Hour Emission of Radioactive Materials from Fukushima I Nuke Plant at the End of June
http://ex-skf.blogspot.com/2011/07/1-billion-becquerels-per-hour-emission.html

(excerpted) That's an amazing reduction from the maximum emission of 2,000 terabecquerels per hour on March 15, it is actually one-2 millionth of the maximum, says TEPCO in the Reference No. 2 of the progress report on the "roadmap" to God knows where.

Is this number, 1 billion becquerels per hour emission, good? TEPCO's Matsumoto, in the press conference on July 19, avoided the judgment, and said he didn't know, but it was one-2 millionth of what it had been on March 15.

On closer reading of the document, though, I noticed one strange thing about this emission number. TEPCO is talking about the radiation emission measured in cesium (cesium-134 and -137), not in iodine equivalence....

.....Instead of 1 billion becquerels/hour, it would be 21.4 billion becquerels/hour in iodine equivalence, or 516 billion becquerels in one day. In less than 2 days, we would be talking about over 1 terabecquerels.

Why TEPCO would do the calculation in cesium instead of iodine equivalent? To make a ready comparison with the previous emission calculations difficult and to give the impression that the number is low?....
