A long and detailed YouTube video by Kyle Hill about how an outdated principle of “there is no safe level of ionizing radiation” still pervades nuclear and radiation policy in spite of continuously mounting scientific evidence to the contrary, contributing to unnecessarily great caution with things like medical imaging, and to negative public perception and panic regarding nuclear power.

The TL;DW is that there is a mountain of evidence that small doses of radiation are harmless due to the body’s natural defenses and self-repair mechanisms, and in fact according to many studies small doses may in fact reduce the risk of cancer compared to baseline rather than increase it (a phenomenon known as hormesis).

    The scientific community is not a unified body, so having scientists questioning any scientific model does not seem like a “wow” moment. But, when the discourse starts including strong vocabulary, admittedly I start questioning/researching claims. And I appreciate it when studies conclude by saying things like: cautious of interpretation is needed, or further studies are warranted, etc.

    Apart from that, sure, maybe the LNT model needs some re-evaluation, maybe not - I dunno, time will tell. Still, to my understanding, one problem with ionising radiation is that the dosage received by people is not always as tightly controlled as needed for it to be safe, despite all efforts. Not even in work environments.

    For example:

    A total of six studies (covering 3,409,717 individuals), which were published between 2006 and 2021 from 4 countries met the inclusion criteria. (…) Pooled analyses indicated that occupational radiation exposure was associated with a 67% higher risk of thyroid cancer

    The researchers assembled a cohort of more than 300,000 radiation-monitored workers from France, the United Kingdom and the United States, employed at nuclear facilities between 1944 and 2016. (…) The study revealed a positive association between prolonged low-dose exposure to ionizing radiation and mortality from these hematological cancers. The study concluded that health risk remains low at low exposure levels. Nevertheless, the evidence of associations between total radiation exposure and multiple myeloma and myelodysplastic syndromes signals the necessity for future radiation studies to expand the discussion on radiation protection and occupational safety measures on a global scale.
