I think you're letting your anger at Ann's attack on Darwinism cloud your judgment. Ann's point that liberals have drastically overstated the consequences of Chernobyl is most certainly true. That's essentially what the IAEA concluded last year. Ann did garble one fact from the IAEA report, there were 4,000 cases of thyroid cancer attributable to Chernobyl, not deaths. 99% of the cases were curable.
The fact that you're quoting Greenpeace ought to indicate taking a step back and looking at this fresh is warranted.
I hadn't even gotten to her attack on "Darwinism" (as if that was some sort of actual movement) when I wrote the Chernobyl piece. She played fast and loose with the facts of the after affects of Chernobyl, including her takes on the numbers of resultant cancers and birth defects.
Finally, if you notice, I did not take Greenpeace's numbers with anything other than a grain of salt. I included them for completeness sake only. I also included links to resources at the bottom of the article so that others could check my results (something the inestimable Ms. Coulter failed to do).
