medium · MCQ · Q-EF87F7
Which of the following radiation quantities is defined as the sum of the weighted equivalent doses in all specified tissues and organs of the body, reflecting the overall stochastic risk of ionizing radiation?
- A.Absorbed dose
- B.Equivalent dose
- C.Effective doseCorrect answer
- D.Exposure
Solution
Effective dose (measured in Sieverts) takes into account the different radiosensitivities of various organs and tissues by multiplying equivalent doses by tissue weighting factors, thus expressing the stochastic health risk to the whole body.
