dosimetry
Quantifying absorbed radiation
Dosimetry is the measurement of radiation exposure, particularly the doses absorbed by people, materials, or environments.
The field is essential in medicine, where precise radiation doses determine treatment effectiveness, and in occupational safety, where workers in nuclear facilities wear dosimeters to track cumulative exposure: The hospital's dosimetry department calculates treatment plans for cancer patients.
