Everybody who has an agenda likes to deny the scientific results.   Exxon-Mobile does it and so does Greenpeace.   Both are distorting reality.

The UNSCEAR report is available on line and has many thousands of references - almost all of them from reputable scientific journals around the world.

The Greenpeace argument about Chernobyl is anecdotal, poorly supported and frankly, if not exploitive, silly.  It is well represented by the diary you link, which is spectacular only for its rhetoric and poor comprehension of the issues.   Basically it is an attempt to substitute a conspiracy theory for a body of widely collected data.

I could post a picture of an amputee and claim he was injured in a coal mine collapse or an oil refinery explosion.  

I could post heart rending pictures of children wallowing in coal dust, or fleeing droughts that may be related to climate change.   However, I won't.  I will continue to write just as I have.
