According to the linear non-threshold model, at what dose does the risk of radiation-induced cancer begin?

The linear non-threshold model posits that even the smallest dose of ionizing radiation carries a risk of inducing cancer. This model assumes a linear relationship between dose and risk, meaning that as the radiation dose increases, the risk of cancer also increases proportionally.

According to this model, the risk of radiation-induced cancer does not start at a specific threshold, but rather acknowledges that there is a possibility of harm at any level of exposure, even down to 0 millisieverts. This suggests that any exposure to radiation, no matter how minimal, can contribute to the cumulative risk of cancer over time.

This perspective is critical in the field of radiation protection and health physics, as it underscores the importance of minimizing radiation exposure whenever possible, given that any dose carries some level of risk.
