Resumo
A special parallel-plate ionization chamber was developed. The motivation for
the construction of this new chamber was mainly to fulfil the need of a reference
system for computed tomography standard beams in the Calibration Laboratory
of IPEN. However, the chamber was tested also in standard radiation beams
of mammography and conventional diagnostic radiology. The chamber was
manufactured at the institute workshop, as simply and cheaply as possible.
Its design differs from the common ionization chambers used in dosimetric
procedures of computed tomography equipment, because it is a parallelplate chamber instead of a cylindrical chamber. However, its dimensions
and sensitive volume are very similar to those of a commercial pencil
ionization chamber. The new ionization chamber was submitted to several
characterization and quality control tests, showing its very good performance.
