Radiation Protection Dosimetry
Radiation Protection Dosimetry
Radiation Protection Dosimetry (pronunciation: ray-dee-ay-shun pro-tek-shun doh-si-meh-tree) is a branch of Dosimetry that focuses on the measurement, calculation and assessment of radiation doses received by individuals working in radiation environments, or members of the public exposed to radiation.
Etymology
The term 'Radiation Protection Dosimetry' is derived from three words. 'Radiation' comes from the Latin 'radiatio', meaning 'shining'. 'Protection' is derived from the Latin 'protectio', meaning 'defense'. 'Dosimetry' comes from the Greek 'dosimetria', from 'dosis' meaning 'a giving or dose' and 'metron' meaning 'measure'.
Related Terms
- Radiation: The emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles which cause ionization.
- Dosimetry: The science of measuring and assessing the dosage of ionizing radiation.
- Ionizing Radiation: Radiation that carries enough energy to detach electrons from atoms or molecules, thereby ionizing them.
- Radiation Protection: The protection of people from harmful effects of exposure to ionizing radiation.
- Radiation Dose: The amount of radiation energy absorbed by the body.
- Radiation Exposure: The state of being exposed to radiation.
Radiation Protection Dosimetry in Detail
Radiation Protection Dosimetry involves the systematic measurement, calculation, and assessment of radiation doses. It is a critical aspect of radiation protection programs, ensuring that radiation exposure is kept as low as reasonably achievable (ALARA principle). The dosimetry process involves the use of dosimeters, devices that measure the amount of energy deposited by ionizing radiation in a material.
Dosimetry is used in a variety of settings, including medical facilities, nuclear power plants, research laboratories, and any other environment where radiation is present. It is essential for ensuring the safety of workers and the public, and for compliance with regulatory requirements.
Radiation Protection Dosimetry also involves the calculation of prospective doses, i.e., doses that might be received in the future, for the purpose of risk assessment and radiation protection planning. This includes the assessment of doses from potential accidents and incidents, as well as from routine operations.
