Which statement about stochastic effects is true?

Stochastic effects are random health effects from radiation where the chance of occurrence increases with dose, but the severity of the effect is not determined by the dose and there is no safe dose threshold. In dental radiology, this means even small exposures carry some risk of outcomes like cancer or genetic mutations, and that risk grows roughly in proportion to the total dose accumulated over time. The key idea is that a higher dose raises the probability of an effect happening, while if an effect does occur, the dose does not dictate how severe it will be. This is why the statement about there being no threshold and the probability increasing with dose is the correct one. The other ideas—having a threshold, causing severe symptoms at any dose, or being inherited traits only—do not accurately describe stochastic effects.
