On thing I never see in these discussions is the toll on workers via radiation exposure. I worked at a nuclear plant in the 1990s and the exposure allowed to outage workers who worked six months a year was something like 5 REM, or 50yrs off radiation in 6 months. Are these deaths included in the statistics? It appears not - part of the issue undoubtedly is causal attribution to a cancer that occurs many years later. A cursory search of the literature suggests that not a lot of work has been done on this.
