The claim that there is a scientific consensus that no level of ionizing radiation is safe is contested in the literature. While the linear no-threshold (LNT) model underpins traditional regulatory frameworks assuming no safe threshold, multiple recent reviews and critiques highlight ongoing debates, evidence of hormesis, and challenges to the LNT model at very low doses.

The claim asserts a universal scientific consensus that no level of ionizing radiation is safe, which directly aligns with the Linear No-Threshold (LNT) model historically used by regulatory agencies. However, the retrieved literature demonstrates active debate and division within the scientific community regarding low-dose radiation safety. Papers such as [5], [10], and [11] explicitly challenge the LNT model, highlighting that experts dispute its validity at low doses and point to evidence of adaptive responses, threshold effects, and a lack of observed excess risk in high natural background radiation areas. Conversely, papers like [3], [4], and [7] uphold concerns regarding potential biological and health impacts of low-dose exposure. Because the sources reflect significant disagreement rather than a unified consensus, the evidence is classified as contested.
