title: [Concepts of dosimetry].
abstract: The effects of exposure to ionizing radiation are determined by the absorbed dose D. The equivalent dose H takes into consideration the variation in probability of a stochastic effect (cancer, leukemia, genetic mutation) based on the quality of the exposure. The effective dose E takes into account the sensitivity of tissues (T) to stochastic effects from radiation exposure. Optimization of radiation exposure to patients in diagnostic radiology in based on diagnostic reference levels (DRL): entrance surface dose or dose-area product for conventional radiology; CT dose index and DLP for CT.
