I watched the BBC account yesterday and found it incredibly biased. It failed to look at any of the medical literature published on Chernobyl documenting the range and severity of illnesses and ailments afflicting those impacted by Chernobyl.
So, I was happy to see this alternative video out debunking the BBC video.
Here is the most comprehensive and definitive account of Chernobyl effects
Yablokov, Alexey, Vassily B. Nesterenko, Alexey V. Nesterenko, and Janette D. Sherman-Nevinger Chernobyl: Consequences of the Catastrophe for the People and the Environment. New York: Annals of the New York Academy of Sciences 1141, 2009. http://www.strahlentelex.de/Yablokov%20Chernobyl%20book.pdf
