Use of a standard ionization chamber at different distances in diagnostic radiology beams. In: INTERNATIONAL CONGRESS OF THE IUPESM, 11th, September 7-12, 2009, Munique, Alemanha. <b>Proceedings...</b> Disponível em: http://repositorio.ipen.br/handle/123456789/16706.http://repositorio.ipen.br/handle/123456789/16706A secondary standard ionization chamber was calibrated, by a primary standard laboratory, at a determined distance. However, in the routine procedures of a calibration laboratory, sometimes the radiation detector cannot be positioned exactly at the calibration distance, for any reason. In this work, the response of a secondary standard ionization chamber was tested to verify the possibility of its use at different distances than at the calibration distance, using the same calibration factor.openAccessionization chambersx radiationcalibration standardsradiation sourcesradiation detectorsdiagnostic techniquesdiagnosisradiologyquality factorTexto completo de eventohttps://orcid.org/0000-0002-7362-2455
