Different assumptions on the extrapolation of the cancer risk vs. radiation dose to low-dose levels, given a known risk at a high dose:(A) supra-linearity, (B)<unk> (C)<unk> -quadratic, (D) hormesis The<unk>  (LNT) is a dose-response<unk>  used in radiation protection to estimate stochastic health effects such as radiation-induced cancer, genetic mutations and teratogenic effects on the human body due to exposure to ionizing radiation. The<unk>  statistically extrapolates effects of radiation from very high doses (where they are observable) into very low doses, where no biological effects are observed. The LNT<unk>  lies at a foundation of a postulate that all exposure to ionizing radiation is harmful, regardless of how low the dose is, and that the effect is cumulative over lifetime. The<unk>  is disputed and is deprecated by a number of international bodies specializing in radiation protection.
