10 CFR 20 & Procedures Flashcards
Define the term Stochastic
Randomly occuring health effects for which the probability of the effect occuring varies linearly with dose and has no threshold
Give an example of a 10 CFR 20 stochastic limit
The annual limit for uniform irradition of the whole body
Define the term non-stochastic
Health effects in which the severity of the effect varies with dose and for which a threshold is beleived to exist.
Give an example of a 10 CFR 20 non-stochastic limit
