Which is the most common form of a stochastic effect?

• A. Cataracts
• B. Teratogenesis
• C. Cancer
• D. Radiodermatitis

Answer: (C)

Stochastic effects are probabilistic outcomes of radiation exposure, meaning they can occur at any dose and the chance increases with dose while the severity of the effect isn’t tied to how large the dose is. Among these effects, cancer stands out as the most commonly observed form after exposure. Epidemiological data from exposed populations show a clear increase in cancer incidence with higher radiation doses, making cancer the primary stochastic risk we worry about. Teratogenesis and hereditary effects are also stochastic in a broader sense, but they are far less common and are often discussed separately or are less consistently observed as a dominant outcome in typical exposure scenarios. Cataracts and radiodermatitis, on the other hand, are deterministic effects, which have a threshold and become more severe with higher doses, not random probabilities. So the best answer is cancer.
