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.
Energy generation is always a trade off. Right now the world is reacting to the fossil fuel funded wars created by one such trade off. We are also in the middle of causing irreversible climate change, which would cause more damage than any amount of meltdowns or nuclear waste could ever get near.
Naturally there are alternatives. If money were no objection then green hydrogen looks pretty nice, and one could always extract heat from the core of the earth as long the technology was safe enough to do so. As soon we have a technology that get proven to be cheaper, safer and more scalable than nuclear we should all switch to that. Buying natural gas from Russia is for multiple obvious reason not that.
