Resumen

RAMOS N, Oswaldo  y  VILLARREAL U, Manuel. Reducing the dose of radiation in diagnostic radiology. Rev. chil. radiol. [online]. 2013, vol.19, n.1, pp.5-11. ISSN 0717-9308.  http://dx.doi.org/10.4067/S0717-93082013000100003.

The number of radiological procedures performed has had a rapid increase during the first decade of the 21st century, achieving a beneficial impact on healthcare. However, this increase leads to a greater exposure to ionizing radiation. The use of ionizing radiation has an inherent risk. Although the risk associated with a radiological examination is minor compared to the natural risk, any added risk, no matter how small, is unacceptable if it does not benefit the patient. The concept of diagnostic reference levels should be used to reduce variations in practice among institutions and to promote optimal dose indicator ranges for specific protocols of the different methods. In general, the basic principles of radiation protection (justification, optimization and dose limits) must be followed to reduce the unjustified increase in the number of procedures being performed.

Palabras clave : Diagnostic reference levels; Radiation dose; Radiological protection; Risk associated.
