Resumo
Free air ionization chambers are used by most primary metrology laboratories as
primary standards of the quantities air kerma and exposure in X-ray beams. The free air
ionization chamber for low energies of the Calibration Laboratory (LCI) of IPEN showed in a
characterization test a problem in the set responsible for the variation of its sensitive volume.
After a modification in the support of the micrometers used for the movement of the internal
cylinder and the establishment of a new alignment system protocol, the tests were redone. The
objective of this work was to present the results obtained in the new condition.
