In fetus, Deterministic effects due to radiation are less likely to occur below the dose of ?: (A) 0.50 Gy, (B) 5 Gy, (C) 0.005 Gy, (D) 0.50 rads
Answer is A. Biological effects of radiation: As exposed dose increases, Threshold dose Effects Deterministic effects/ Non-stochastic effects Severity of effect increases Yes - For fetus - 0.50 Gy (50 rads) - Includes all harmful tissue reactions, excluding stochastic effects. Stochastic effects Frequency of occurrence increases No - Genetic influence, carcinogenesis
