Chapter 10: Dose Limits for Exposure to Ionizing Radiation

What are the two types of damage that radiation can cause?

• Genetic and somatic damage

• Physical and chemical damage

• Acute and chronic damage

• None of the above

Exposure limits are based on minimizing risk while allowing for ______ and occupational use.

• medical

• recreational

• educational

• residential

Limits for radiation exposure are designed using which concept?
