The link that Jim Martin provided above is on another report for the need to further expand the mandatory evacuation zone around the Fukushima-1 nuclear complex. There is more and more evidence that the radiation readings out to 25 miles are more than twice than the "trigger" for defining the evacuation zone in and around Chernobyl. Here's a few more words on the topic from the Union of Concerned Scientists (emphasis added):

"The IAEA (International Atomic Energy Agency) is reporting that measured soil concentrations of Cs-137 as far away as Iitate Village, 40 kilometers northwest of Fukushima-Dai-Ichi, correspond to deposition levels of up to 3.7 megabecquerels per square meter (MBq/sq. m). This is far higher than previous IAEA reports of values of Cs-137 deposition, and comparable to the total beta-gamma measurements reported previously by IAEA and mentioned on this blog.

This should be compared with the deposition level that triggered compulsory relocation in the aftermath of the Chernobyl accident: the level set in 1990 by the Soviet Union was 1.48 MBq/sq. m."

Evidently the Union of Concerned Scientists has been primarily focusing their own energy on preparing and presenting testimony at an energy hearing in Washington, DC, this week.
