Dosimetry is the measurement and calculation of the absorbed dose of ionizing radiation in the human body. This includes determining the amount of radiation received by individuals in medical settings, occupational environments, and during radiological emergencies. Dosimetry is crucial for ensuring the safety of individuals exposed to radiation and for monitoring radiation levels in various settings to minimize potential health risks. Dosimeters are devices used to measure radiation exposure, and different types of dosimeters are used depending on the specific needs of the situation. Dosimetry is an important field in radiation protection, medical imaging, and radiation therapy.
