What is exposure to internal organs from internal sources known as?

• A. Committed Effective Dose Equivalent (CEDE)
• B. Annual Limit on Intake (ALI)
• C. Committed Dose Equivalent (CDE)
• D. Collective Dose

Answer: (A)

Internal exposure from radioactive material taken into the body deposits energy in multiple organs over time. To capture the overall risk from that internal contamination, we first determine the committed dose equivalent for each organ, reflecting the dose that organ would receive over a future period (typically about 50 years for adults). These organ doses are then weighted by tissue weighting factors that reflect the varying sensitivities of different tissues, and summed. The resulting value is the committed effective dose equivalent. This single quantity expresses the total potential risk to the whole body from an intake of radioactive material, linking internal sources to a whole-body risk rather than focusing on a single organ.
