I was studying in Russia when Chernobyl occurred, and I dated a woman from northern Ukraine who was a teenager at the time of the accident. I saw the results of the accident firsthand - basically everyone under the age of 10 was affected - hair loss, skin rashes and nausea in the immediate years after, cancer and early death later.
But even so it isn't fair to judge the safety of nuclear power by Chernobyl. Chernobyl happened because the Soviet system had become incredibly incompetent, and technical decisions were being made by thugs.
The capitalist system quite often also becomes incredibly incompetent and has its technical decisions made by thugs. Tepco, the company that runs the Fukushima plant, has a long history of corruption, faked security reports and blatant incompetence.
What makes nuclear power unsafe is human error more than technical failure. That's the aspect the naive technocrats (like the guy who wrote this article) always ignore.
