UBEDA DE LA C, Carlos et al. Quantities and units for patient dosimetry in diagnostic and interventional radiology. Rev. chil. radiol. [online]. 2015, vol.21, n.3, pp.94-99. ISSN 0717-9308.

Because diagnostic and interventional radiology procedures represent one of the main sources of irradiation by ionizing radiation in the population, it has become a priority to become familiar with the quantities and units that account for patient dosimetry. There are countless documents and international recommendations on names, concepts, definitions and areas of application for various quantities and units used in patient dosimetry, in interventional and diagnostic radiology procedures. However, national legislation is not updated in this regard and does not provide, in any of its documents, an updated glossary that enables finding this type of information quickly and precisely. Therefore, this review paper presents in a didactic way and in plain language, the main quantities and units to be used in the dosimetry of patients undergoing diagnostic and interventional radiology procedures.

Keywords : Air kerma area product; Dosimetry; Entrance surface air kerma; Incident air kerma; Quantities.
