SELF-DETERMINATION IS A TOUGH TASKMASTER:

How We Can Get Clean Energy--Is Nuclear Power Safe? (Robert Zubrin, 29 Apr 2022, Quillette)

[F]ar from increasing the radiological exposure of the public, nuclear power plants reduce it. Coal contains radioactive constituents. Worldwide, coal-fired power stations release some 30,000 tons of radioactive radon, uranium, and thorium into the atmosphere every year. They also emit millions of tons of highly toxic chemical ash containing mercury, arsenic, and selenium, not to mention over 10 billion tons of CO2 per year. In addition to 10 million tons of CO2, a single 1,000 MWe coal-fired power plant produces 200,000 tons of ash annually and, as well as several hundreds of tons of mercury and other chemical poisons, sends some 27 tons of radioactive material--half radon, the other half uranium and thorium--right up the chimney. The amount of uranium and thorium emitted to the environment as pollution by coal-fired power plants would be more than enough to fuel every nuclear power plant in the country to produce equivalent power without any of the CO2, toxic gas, or radiological emissions.

Natural gas is much cleaner than coal, but it contains radioactive radon. Not much, to be sure, typically about 0.03 microcuries per cubic meter. But that adds up. A 1000 MWe natural gas power plant sends about 8 curies of radon into the environment every month. That's just about the same as what the Three Mile Island nuclear power plant let loose just once--during its world-famous meltdown in March 1979!
