Rad Bio Cumulative Review

Front

What is the dose–response model for deterministic effects?

Back

Typically follows a linear or S-shaped curve starting above zero (threshold).

Front

What is a stochastic effect in radiation biology?

Back

An effect that occurs by chance, such as cancer, where the probability increases with dose but the severity does not depend on the dose.

Front

How do you calculate the Equivalent Dose (EqD)?

Back

Using the formula: EqD = D × Wr, where D is the absorbed dose and Wr is the radiation weighting factor.

Front

What is the radiation weighting factor (Wr) for alpha particles?

Back

20.

Front

What is NCRP Report #116 about?

Back

It outlines the dose limits for occupational and public exposure to ionizing radiation.

Front

What is the difference between deterministic and stochastic effects?

Back

Deterministic effects have a threshold and severity increases with dose, while stochastic effects have no threshold and probability increases with dose.

Front

What is the absorbed dose (D) measured in?

Back

Gray (Gy).

Front

What is the significance of the linear-quadratic model in radiation biology?

Back

It describes the relationship between dose and response for certain types of biological effects, particularly for low doses.

Front

What is the formula for calculating the absorbed dose from a given Equivalent Dose?

Back

D = EqD ÷ Wr.

Front

What are some examples of deterministic effects?

Back

Skin burns, cataract formation, and radiation sickness.
