Google also turns up what appears to be the original source for those oft-repeated statics http://nextbigfuture.com/2011/03/deaths-per-twh-by-energy-so...

It's fair to say the author's methodology is interesting. Only 50 deaths from Chernobyl count... as it would be "tenuous" to count other people that eventually died from radiation poisoning (even using the figures accepted by bodies responsible for promoting atomic energy). It's apparently not "tenuous" to count ballpark estimates of a million lives shortened due to coal particulate poisoning, however, or indeed to guesstimate 1/6 of all roofing deaths are likely to be from solar. It's something of an understatement to say this is not the most intellectually honest exploration of statistics around an issue.

Compare with the New Scientist's claim - based on a study by the IAE - that the ratio should be around 14:1 for coal, and 1.5:1 for natural gas. Better than coal, certainly, but not spectacularly safe even compared with burning other fossil fuels https://www.newscientist.com/article/mg20928053-600-fossil-f...

Not sure why quoting the WHO is "interesting", unless you mean "interesting" as in "a good way to proceed".

http://www.who.int/mediacentre/news/releases/2005/pr38/en/

They say the death toll could reach 4000 (from the pool of emergency workers), but so far only 50 have been confirmed.

' [..] the radiation-induced increase of about 3% will be difficult to observe.'

'Poverty, “lifestyle” diseases now rampant in the former Soviet Union and mental health problems pose a far greater threat to local communities than does radiation exposure.'

'Persistent myths and misperceptions about the threat of radiation have resulted in “paralyzing fatalism” among residents of affected areas'

'Notes Vinton, “The most important need is for accurate information on healthy lifestyles, together with better regulations to promote small, rural businesses. Poverty is the real danger. We need to take steps to empower people.”'


If you're going to count a WHO estimate on lives shortened due to coal power in your fatality statistics, which the author does, it's probably not a good idea to dismiss the equivalent estimate of 4000 for Chernobyl, which the author also does. Even organizations existing to promote atomic energy aren't disputing the validity or relevance of that figure

I mean, if you're doing a sincere comparison with "people whose lives may have been shortened by coal dust" and "back of the envelope guesstimate how many people die installing domestic solar", you simply don't pick "people definitely proven to have died from radiation poisoning at Chernobyl" as your comparison point.

Coal would look remarkably safe (which it isn't) if you required similar standards of proof of coal dust rather than lifestyle factors being the cause of premature death.


While both the coal dust and Chernobyl future deaths are somewhat statistical in nature, there is a huge difference that you would acknowledge if you were sincere. The coal deaths are already occurring. They are, as far as I can tell, sufficiently statistically significant that they are not seriously in question.

The future Chernobyl deaths are just that: predictions about what may happen in the future. They think it could happen, but they don't know. And due to the extremely low level of the signal, it will be very hard to tell if they do occur, because as the WHO report states, other effects such as poverty are much more significant.

So, no, the comparison to coal dust is not unfair at all.

But, for the sake of argument, let's completely ignore the coal dust and other respiratory or global warming effects, and concentrate on just the proven accidents. Heck, let's be super unfair and leave in the estimated possible statistical future deaths from Chernobyl, but only consider the documented deaths from coal accidents. That gives us 4000 deaths for Chernobyl and 4000-6000 per year for coal. So even when being totally unfair towards nuclear, it is somewhere between 20-40x safer than coal.

When you level the playing field, you have the 50 deaths from Chernobyl and around 131 others, though that includes lots of accidents not related to power generation. Around 180. Let's double it and call it an even 400. So 10x fewer deaths than coal. Except that's per year vs. since ever. So we're talking around 500-1000x safer.

No matter how you slice and dice the numbers, nuclear power is vastly safer than existing means of power generation, even given the sorry state of the industry today.

Of course, we should still be doing as much solar as we can (just be careful when installing!), and we should improve reactor designs so they are even more safe. For example using the liquid fuel thorium reactors, or concepts such as PIUS, which uses passive mechanisms relying mostly on physical laws to shut down and cool the reactor, rather than active mechanisms that can fail as they did at Fukushima-Daiichi. And hope that one or more of the multitude of nuclear fusion projects makes a breakthrough.


> While both the coal dust and Chernobyl future deaths are somewhat statistical in nature, there is a huge difference that you would acknowledge if you were sincere.

OK then, I sincerely acknowledge that the estimate of 4000 Chernobyl casualties is much more widely accepted (including by the nuclear industry) than the WTO's more speculative guess at how many people are having their lifespan reduced by exposure to coal particle dust. I'm not sure why you would think otherwise, but then I'm also perplexed by your assumption that none of the 3940 total casualties the WHO predicts from increases in rates of cancer and leukaemia among those most closely exposed to Chernobyl radiation have happened yet.

The lack of confirmed Chernobyl deaths is because - as the report you linked to states - cancers are common cause of death among people not exposed to nuclear accidents, not because 50 acute radiation sickness victims and 9 kids with thyroid cancer are the only people living or working near Chernobyl to have died a bit young over the last 30 years. I mean, I'm not sure any individual lung cancer has been directly proven to be a result of working down a coal mine either, but it would be an unusually outspoken proponent of coal that argues that it should be discounted as a risk altogether because of that, or because of difficulties gauging the precise size of the effect when miners tend to be poor and smoke a lot.

I'm going to go out on a limb and consider a published study suggesting nuclear is around 14 times safer than coal[1] and 1.5 times safer than natural gas a little more valid than your own back-of-the-envelope exercise, or indeed a blogger whose use of statistics is rather creative.

[1]though much as with flying being safer than driving, that's to a large extent because nobody is suicidal enough to run a nuclear plant with safety standards comparable to those of Chinese coal mines.
