Description
A tandem ionization chamber system has been developed to be applied for conventional diagnostic radiology energy range dosimetry. This system consists of two ionization chambers with different collecting electrode materials: aluminum and graphite. Both chambers have a sensitive volume of 6 cm3. Characteristics as saturation, ion collection efficiency, linearity of chamber response versus air kerma rate and energy dependence were determined. The results of energy dependence allowed the determination of the tandem curve. It can be used in quality control programs of diagnostic radiology area. All measurements were carried out at the Calibration Laboratory of IPEN. (author)
