Effective dose is

Effective dose is

• A. dose estimated at the skin surface and used to directly infer radiation associated risk, expressed in mSv
• B. the dose to bone marrow only
• C. the total energy delivered to the body
• D. the maximum absorbed dose by any organ

Answer: (A)

Effective dose is a single, risk-based quantity used to estimate the overall stochastic risk from radiation exposure by combining the different doses received by various tissues, each weighted by how sensitive that tissue is to radiation. It is expressed in sieverts (mSv) so you can compare the relative risk of different imaging procedures. In dental practice, this helps clinicians gauge and compare the potential cancer-risk implications of different exams, such as small intraoral films versus panoramic or CBCT, rather than focusing on a single organ’s dose or on the total energy deposited. The other ideas are narrower: bone marrow dose alone is only part of the picture, the total energy delivered to the body reflects absorbed energy (not adjusted for tissue sensitivity), and the maximum absorbed dose by any organ ignores the contributions and sensitivities of other tissues. Effective dose, by weighting organ doses and summing them, provides the best overall risk estimate in a single value.
