Now here is an interesting chart from this website:
Anil Markandya and Paul Wilkinson (2007) published an analysis in the medical journal The Lancet, which compared the death rates from the major energy sources.2 In this study they considered deaths from accidents, such as the Chernobyl nuclear disaster, occupational accidents in mining or power plant operations, and premature deaths from air pollution.3
This study was published in 2007, before the 2011 Fukushima Daiichi nuclear disaster in Japan. You might assume that the figures from this analysis therefore understate the death toll from nuclear energy, but in fact the opposite is true. Later in this article we look at a more recent study on the safety of low-carbon energy sources, published in 2016 which includes Fukushima impacts, and in fact reports a lower death rate than Markandya and Wilkinson (2007).4 There were no direct deaths from the Fukushima Daiichi disaster. The official death toll was 573 people, all of which were premature deaths from evacuation and displacement of populations in the surrounding area.5 In 2018, the Japanese government reported that one worker has since died from lung cancer as a result of exposure from the event.
Nuclear energy is by far the safest energy source in this comparison – it results in more than 442 times fewer deaths than the ‘dirtiest’ forms of coal; 330 times fewer than coal; 250 times less than oil; and 38 times fewer than gas. To be clear: the figures in this analysis was based on energy production in Europe where anti-pollution regulation and technologies are already well ahead of many countries in the world; in this case the death rate from fossil fuels may even be understated.
