What aspect does a whole-body dose account for in radiation exposure?

A whole-body dose encompasses the total amount of radiation exposure that a person receives, accounting for both external and internal sources of radiation.

External radiation exposure refers to radiation coming from outside the body, such as that from radioactive materials in the environment or from medical imaging. Internal radiation exposure occurs when radioactive substances enter the body, potentially through inhalation, ingestion, or absorption through the skin.

The calculation of a whole-body dose integrates both of these exposure types because the health effects of radiation can arise from either source. By considering both external and internal exposures, professionals can assess the overall risk and potential health impacts that an individual might face due to radiation exposure. This comprehensive view is essential for effective monitoring and protection strategies in environments where radiation is present.
