Coal contains between 1 to 10 ppm of uranium. Globally about 8 billion tonnes of coal is burned every year to generate electricity. Thus between 8 thousand and 80 thousand tonnes of Uranium is emitted into the atmosphere every year.

MW by MW, coal plants emit more radiation than nuclear on average. This is true even when taking accidents into account, and not by a small factor.

We’d genuinely be better off ignoring most accidents and just using nuclear. Not to mention that coal ashes and emissions are chemically carcinogenic as well.
