Non-stochastic effects have which type of dose-response relationship?

• Threshold

Which of the following will influence the biological effects produced by ionizing radiation?

• Dose Rate

• Area Exposed

• Cell Sensitivity

• All of the following are correct answer choices.

The Law of Bergonie and Tribondeau states which type of cells as MOST radiosensitive?

• High proliferative rate; poorly differentiated

• Low proliferative rate; highly differentiated

• High proliferative rate; highly differentiated

• Low proliferative rate; poorly differentiated

Somatic effects will be expressed in:

• Irradiated individual only

• Exposed individual and family that they live with.

• Offspring

• At first the individual only but then spread to the community.
