I'm not looking it up but I wonder what the statistics are for deaths and serious injuries among people who work in electrical power companies overall and what percentage of them are due to radiation exposure. I'm speculating that it's comparable to looking at deaths & injuries from all forms of transportation and what percentage of them are from airline accidents - driving your car is the most dangerous way to travel but we think nothing of it, while flying is statitically safest yet it gets so much publicity because people are taken out in job lots when there is the rare accident.
If this nuclear power incident turns out to be contained with only very little contamination to the immediate area it will actually show that nuclear power is pretty damned safe in light of the battering that plant took. I wouldn't want to depend on it totally or forever but it is a remarkably efficient way to keep things going until safer and greener forms of energy production are developed.
