What does the linear no-threshold (LNT) model suggest?

The linear no-threshold (LNT) model suggests that any exposure to radiation carries a risk of harmful effects, irrespective of the dose. This model operates under the premise that there is no safe threshold of radiation exposure below which there are no associated risks of cancer or other health effects. Therefore, even the smallest amount of radiation could potentially contribute to the risk of cancer, which emphasizes the importance of minimizing radiation exposure whenever possible. It's fundamental in radiation protection and regulatory practices, promoting a precautionary approach to radiation safety. This principle aligns with the understanding of how biological systems may respond linearly to radiation, indicating that risk accumulates with each increment of exposure.
