How is effective dose calculated?
Understand the Problem
The question asks how effective dose is calculated in the context of radiation exposure, giving several options involving different factors. We need to identify the correct formula or principle used to determine effective dose.
Answer
Effective dose is calculated by multiplying the equivalent dose by a tissue weighting factor.
The final answer is C. By multiplying the equivalent dose by a weighting factor which takes account of the radiosensitivity of the tissues being irradiated.
Answer for screen readers
The final answer is C. By multiplying the equivalent dose by a weighting factor which takes account of the radiosensitivity of the tissues being irradiated.
More Information
The effective dose is a tissue-weighted sum of the equivalent doses in all specified tissues and organs of the human body.
Tips
Many people confuse the weighting factor as the type of the radiation being used, but it is the radiosensitivity of the tissues being irradiated.
