What I actually logged on to post, I recalled reading in Scintific American in the 1970s that nuclear fission was a lot safer than coal, so I googled. Google was not cooperative but I eventually found https://ourworldindata.org/safest-sources-of-energy
and, summarising, deaths per TW-h and CO2 equivalent per GW-h
Brown coal 32.72 deaths
Black coal 24.62 deaths and 820 t
Oil 18.43 deaths and 720 t
Biomass 4.63 deaths and 78 to 230 t depending on fuel
Nuclear fission 0.07 deaths and 3 t
Wind 0.04 deaths and 4 t
Hydro 0.02 deaths and 34 t
Solar 0.02 deaths and 5 t
All numbers allegedly over the full life cycle. I would expect there to be substantial uncertainty.
If my arithmetic is correct, this means that if we value a human life at 1 million dollars, the hidden and unpaid for (by power companies and users) cost of brown coal power in human life is about 3 cents per kilowatt hour.
