Tissues have the capacity to repair radiation damage to a certain degree. However, some damage

cannot be repaired and remains weakened, especially with repeated exposures. This is called:

a. a long-term effect.
b. radioresistant tissue.
c. a cumulative effect.
d. a stochastic effect.

c. A cumulative effect refers to the theory that radiation-exposed tissues accrue damage and may function at a diminished capacity with each repeated exposure.
