本文讨论了线性无阈值模型在低剂量辐射风险中的争议,以及如何通过更好的数据和评估方法来解决这一争议。
原文开头
When US President Trump signed an executive order in May 2025 seeking to streamline the adoption of nuclear energy by directing federal agencies to reconsider whether radiation protection standards have been unnecessarily strict, he reignited a debate that has smoldered in radiation science for decades. At the heart of the controversy is the linear nonthreshold (LNT) model—the idea that any amount of radiation, no matter how small, has damaging biological effects. Resolving whether LNT is a reasonable precaution or a costly misapplication of incomplete science will require not just better arguments, but better data. The science underlying low-dose risk (less than 100 milligray, a measure of how much radiation is absorbed by living tissue) is incomplete. …
