People misunderstand the risk. The amount of radiation you need to be exposed to for a 50% chance of getting cancer would be a fatal dose from radiation poisoning. The way people end up with cancer isn't by one person getting a large dose, it's by a million people each getting a small dose, so that they each have a one in ten thousand chance of getting cancer and then a hundred of them do.
Which is exactly the same thing that happens with coal -- not least because coal is radioactive and burning it puts the radioactive materials into the air.
Except that coal does it as a consequence of normal operation rather than only in the event of a catastrophic failure.
About the only practical way to do that is to eat them, at which point you're in the same category as any other adulterated food. How is caesium any scarier than prions or mercury or various pesticides or a thousand different chemical carcinogens?
By this logic people should be deathly afraid of coal and what it puts into the air.
