According to the LINEAR Hypothesis, what is implied about radiation damage at any dose?

• A. No damage at low doses
• B. Damage only above a threshold
• C. Some damage can occur at any dose
• D. Damage only at high doses

Answer: (C)

The main idea here is that radiation risk increases in direct proportion to the dose, with no safe lower limit. In the linear no-threshold model, every nonzero dose carries some chance of causing damage, so even the smallest exposures can lead to damage, though the probability grows with dose. This distinguishes stochastic effects, like cancer risk, from deterministic effects which have definite thresholds. So at any dose, some damage can occur, even if the amount or severity depends on how large the dose is.
