Dr Ian Fairlie -Low-dose radiation a health in the nuclear industry , as well as in medicine

Dr Ian Fairlie , 12 Mar 23

This is an important new study in the BMJ  …a meta analysis of 93 health studies. https://www.bmj.com/content/380/bmj-2022-072924

The authors conclude, inter alia, “Our findings suggest that radiation detriment might have been significantly underestimated, implying that radiation protection and optimisation at low doses should be rethought.” And also

“This finding has considerable implications for the system of radiological protection, assuming that the extrapolation is permissible, even, for example, over the restricted dose range 0-0.5 Gy. This added risk would nearly double the low dose detriment.”

These conclusions are supported in an accompanying BMJ editorial https://www.bmj.com/content/380/bmj-2022-074589

In initial thoughts: we should note that almost all of these studies concern medical exposures (ie for diagnostic or for cancer treatment purposes). Environmental exposures are hardly mentioned at all. However radiation exposures do occur to nuclear workers and to populations near nuclear facilities. Therefore we should be concerned about their cardiovascular health risks too.

For example,  there exists a 2017 INWORKS study – strangely omitted in this BMJ meta analysis – of increased deaths to nuclear workers from cardiovascular diseases. see

 It remains to be seen whether the nuclear establishment (ICRP, UNSCEAR, IAEA, WHO etc) will pay any attention to this study.
