Content Summary : Since most of the health risk from nuclear power is imposed on people living in the far future,a simple number for the global YOLL is not very instructive. For another perspective let uslook at the implications of using nuclear power on a large scale. The population of the worldis about 6 billion and the electricity consumption 12000 TWh/yr. Both will increase,especially the latter, although saturation can be expected eventually. Technologies willcertainly evolve and nuclear fission reactors are unlikely to be more than a stopgap, perhapsfor a century or so, until cleaner sources of energy mature. Since details do not matter for thefollowing argument, we take simple round numbers.
