Stochastic and Nonstochastic Radiation Effects

Question 1

How does stochastic effects occur?

Answer 1

Occur as a direct function of dose. (does not have dose threshold) ex: cancer, induction, and genetic mutations.

Question 2

What are Nonstochastic effects?

Answer 2

Are somatic effects that have a threshold and that increase in severity with increasing absorbed dose. ex: erythema, loss of hair, cataract formation, and decreased fertility. (Nonstochastic effects require larger radiation doses to cause serious impairment of health.)
