Committed Effective Dose Equivalent (CEDE) refers to exposure to internal organs from internal sources?

• A. Committed Effective Dose Equivalent (CEDE)
• B. External Dose Equivalent
• C. Cumulative External Dose
• D. Total Organ Dose

Answer: (A)

CEDE represents the long-term dose to body tissues that results from a radionuclide taken into the body. When a person inhales or ingests radioactive material, it stays in organs and continues to emit radiation over time as it decays and as the body clears it. The dose from that internal source is accumulated—committed—over time, and it is weighted by the sensitivities of different tissues to reflect overall risk. So CEDE is about exposure to internal organs from internal sources and is used to estimate lifetime risk from an internal intake. It’s distinct from external dose concepts (radiation coming from outside the body) and from total organ dose or cumulative external dose.
