Acute high-dose radiation is a significant health hazard. We know this from atomic bomb survivors, the Chernobyl first-responders, and some other instances, and it's horrible. However, lots of people have gone around into low radiation zones and found really sick people with horrible diseases, and claimed it was linked to the radiation. What they haven't done is linked those diseases to low-dose radiation with anything near scientific rigor. It's very often just confirmation bias. "There's low-dose radiation here, and cancer, therefore low-dose radiation caused this cancer." I'm not saying we have enough data to show that low-dose radiation causes no cancer. It just doesn't cause an easily-measurable amount, if any. A counterexample is places like Ramsar, Iran, where the natural background radiation is 80x higher than average. Would you guess that the cancer rate is higher than average? https://en.wikipedia.org/wiki/Ramsar,_Mazandaran#Radioactivity https://en.wikipedia.org/wiki/Ramsar,_Mazandaran#Radioactivi...
