These somatic and stochastic biological effects are random and there is no threshold amount of exposure that must be received for them to occur. The severity of the effect is random.
short-term somatic effects
long-term somatic effects
genetic effects
none of these are correct
long-term somatic effects (stochastic)
Short term somatic effects (deterministic)- associated with high-dose exposures. They are predictable and their severity is dose dependent.
