Despite its widespread use, the LNT model has several critics. Some argue that it overestimates the risk of cancer at low doses of radiation, leading to unnecessary fear and costly regulatory measures. Critics suggest that the body's natural repair mechanisms can deal with low-level radiation damage, and they advocate for alternative models such as the threshold model or hormesis. The hormesis model, for example, posits that low doses of radiation might actually have beneficial effects by stimulating protective biological responses.
