According to the linear non-threshold model, what is the risk correlation for exposure to radiation?

• A. A zero risk with minimal exposure
• B. A one in 1 million chance of early death with high exposure
• C. A one in 1 million chance of early death from 10 mREM
• D. No correlation with exposure

Answer: (C)

The linear non-threshold (LNT) model posits that any exposure to ionizing radiation, no matter how small, carries some risk of causing cancer or other health effects. This model suggests that the risk of harm increases linearly with the dose, without a threshold below which no risk exists. In this context, stating a one in 1 million chance of early death from an exposure of 10 mREM is aligned with the principles of the LNT model. It quantifies the risk associated with a specific dose of radiation, asserting that even minimal exposure still contributes to cumulative risk. The model supports the idea that risk is proportional to the amount of radiation received, reinforcing the importance of minimizing exposure whenever possible. Thus, the response indicating this specific risk correlation at 10 mREM is accurately reflecting the way the LNT model interprets radiation exposure impacts. The other options do not adhere to this risk association; they either imply no risk or incorrect estimation that doesn't align with the principles of the model.
