Depends on yield, cleanup , isotopes used and how many generations of retards , cripples and maimed you are willing to risk. Hiroshimans had nowhere to go, so they survived..also, radioactivity effects on populations are severely stratified: some people show remarkable resilience against radiation damage, while others die fast from radiation .

Been to Hiroshima , been to Pripyat. Have my own calibrated alpha/beta/gamma detector.

Remember , part of the profitability of war is the material destruction itself and the ensuing debt financed expensive rebuilding that enables more money creation.

Yes, modern hydrogen bombs are different and were designed to be so, but immediate blast radius damage from them too esp. In megatons range is devastating to buildings as well.
