Effects of radiation that become more severe as dose increases are called:

• A. Dose-response curves
• B. Deterministic effects
• C. Genetic effects
• D. Somatic effects

Answer: (B)

Deterministic effects have a dose threshold, and once that threshold is crossed, their severity increases as the dose goes up. In clear terms, the more radiation you receive above a certain level, the worse the effect becomes, with tangible signs like skin erythema, hair loss, cataracts, or acute radiation sickness depending on which tissues are involved and how large the dose is. This distinguishes them from genetic effects, which refer to heritable changes and don’t describe immediate severity in the irradiated person, and from stochastic risks that describe probability of effects (like cancer) without a fixed severity tied to dose. Dose–response curves describe how effects relate to dose, but the specific category that becomes more severe with increasing dose is deterministic effects.
