How do you measure health effects of different sources of electric energy? If you compare deaths per TWh, then nuclear power is much, much safer then coal energy.

Nuclear power has problem with public perception.

One source of this media. Media loves to write and talk about nuclear incidents and really blow this out of proportion to real health hazards. For decades, newsrooms have operated under the premise that 'if it bleeds it leads'. If something happen infrequently and could have big impact on many people it makes more interesting news story.

Flight industry has similar public perception problem. Transport statistic shows that travel by airplane is safer the car, yet much more people fear flying then driving. A deadly airplane crash is reported in all newspapers, the daily deaths from the car crashes are not even mentioned.

Popular tv-series "The Simpsons" (three eyed fish, green radioactive goo), movies Spiderman (if I get bitten by a radioactive spider), Hulk (gamma rays make you super strong), China Syndrome, the german movie "Die Volke", etc., doesn't help much with education about nuclear power.

Deaths from burning coal don't get much attention in the media, because the happen continuously each year, over decades.

If you want to factor in health then private health insurance would be the way to do it.
