NettetThe linear no-threshold model (LNT model) is a conservative model used in radiation protection to estimate the health effects of small radiation doses. According to the LNT model, radiation is always considered harmful with no safety threshold. Nettet1. des. 2024 · These range from linear–no threshold, which suggests any exposure (even background radiation) is harmful, to the possibility that low-dose radiation exposure is beneficial (radiation hormesis). Three dose–response models used in radiation biology are linear no-threshold, linear threshold, and linear quadratic.

NettetAccording to the threshold hypothesis radiation results in cancer only when there is enough radiation to overwhelm the threshold mechanism. One could mix these hypothesis and assume that there is some linear component but that the major effect is a threshold effect. The above evidence suggests that the linear component is very small.

Nettet1. jul. 2024 · Currently, the USEPA uses the linear no-threshold (LNT) model to estimate cancer risks and determine cleanup levels in radiologically contaminated environments. The LNT model implies that there is no safe dose of ionizing radiation; however, adverse effects from low dose, low-dose rate (LDDR) exposures are not detectable.
