Did you know that coal ashes is also a bit radioactive? Contrary to the fuel of a nuclear power plant which is very radioactive but well contained, these ashes are just spread in the atmosphere during normal operation.
We, at least I, were not thinking about normal operation. This is about events like the shelling of the largest nuclear plant in Europe. There are others which the Kremlin will attempt to take with force as well. I was unable to purchase iodine tablets as they were out of stock already.
