This chamber was tested and calibrated in low-energy X-ray beams in accordance with international recommendations, and it showed a satisfactory level of performance, mainly with regard to its main use, namely formation of a tandem system for confirmation of half-value layers in X-radiation beams previously determined by the conventional method. In this developed system no absorbers or special setups are necessary.495-500openAccessionization chambersquality controlx-ray equipmentx radiationcalibrationperformanceArtigo de periódico45810.1016/S0969-8043(03)00026-5https://orcid.org/0000-0002-7362-2455
