Nonstochastic effects of radiation are also known as?

• A. Random effects
• B. Deterministic effects
• C. Somatic effects
• D. Chronic effects

Answer: (B)

Nonstochastic effects of radiation are referred to as deterministic effects because they follow a threshold dose-response relationship. This means that a certain dose of radiation must be reached before these effects begin to manifest, and the severity of the effects is directly proportional to the amount of radiation exposure. Examples of deterministic effects include skin burns, cataracts, and radiation-induced organ damage.

These effects contrast with stochastic effects, which are random and may occur without a threshold dose. Stochastic effects, such as cancer or genetic mutations, have a probability of occurrence that increases with greater exposure, but the severity of the effect does not depend on the dose.

Understanding the distinction between deterministic and stochastic effects is crucial in radiography and radiation protection because it helps inform safety guidelines and the management of radiation exposure among patients and healthcare professionals.
