What is the number of deaths per TWh by energy source?

What is the number of deaths per TWh by energy source? Here is a nice and interactive chart at the IBM research website Many Eyes (http://www-958.ibm.com/software/data/cognos/manyeyes/visualizations/2e5d4dcc4fb511e0ae0c000255111976) allowing you to compare the number of deaths measured per terawatt hour (TWH) attributed to each of the main sources of energy worldwide: coal, oil, natural gas, nuclear, hydro, and biomass as well as the proportion that each contribute to global energy production... data is from a variety of resources including World Health Organization (more info could be found here http://nextbigfuture.com/2011/03/deaths-per-twh-by-energy-source.html)... it is not surprising coal is the most lethal energy source largely due to its particulate emissions... by comparison nuclear is doing quite well (the data already includes the deaths attributable to Chernobyl)... and this is while the data does not include the effects of global warming due to the use of coal, oil etc, so the numbers for these sources could be even higher...
