Less radioactive EMISSION during NORMAL OPERATION than coal plants (and I think that ignores radioactivity released in uranium mining). The amount of radioactivity in the spent fuel rods of a nuclear plant is vastly higher than that liberated by a coal plant.
BTW, your chance of dying from cancer in your lifetime is about 20%, so I'm not sure that the 1/5 figure you gave there means anything.
There is a place in the US that has a rather peculiar name of Cancer Alley. It is not a nuclear testing area, nuclear waste deposit area or area for nuclear plants. It is an area know for its petrochemical plants. It illustrate quite well the difference of nuclear waste that people are scared of, and fossil fuel waste that people accept as just normal part of life.
