No common factors? Really? They are both used to make energy.
Coal is 1,888 times more deadly than nuclear power when measured in deaths per MW. According to http://www.forbes.com/sites/jamesconca/2012/06/10/energys-de...
And that includes Chernobyl, and uses the worst case scenario for the effects of radiation!
If you removed Chernobyl and used http://en.wikipedia.org/wiki/Radiation_hormesis instead (which is more likely to be accurate) the deaths attributed to nuclear power would go even lower.
Nuclear power is by far the safest form of energy on earth - it even beats solar power. It is so very very very stupid we don't get 80% of our energy from it.
