It should be noted that up to 4,000 microSieverts was measured near the plants. Measurements have been in the 3,000 mSV range. That's over the 2K mSV "severe radiation poisoning" level cited in the chart

mSv stands for milli-Sievert, and uSv is micro-Sievert. 4000 uSv would be equivalent to 4 mSv, which is where Randall has it listed.

Dammit. Thanks for the correction. I meant MICRO-Sievert.
