As part of the program to ensure quality in nuclear medicine unit, in addition to diagnostic
procedures, are evaluated activity meters, which is intended to measure the aliquot of radiation
of radionuclides and / or radiopharmaceuticals that are administered to patients undergoing
diagnostic investigation and / or therapeutic treatment. The good operating condition of dose
calibrators is essential to ensure efficiency, safety and reliability of the measurements, once the
lack of accuracy in the responses of these equipments can cause significant errors in the
activity administered to the patient and may result in poor quality images resulting in the
repetition of examis and interference in the successful treatment of the patient. This study aims
to, considering the need for constant evaluation of the functioning of the activity meters and the
fact that this issue be part the responsibilities of the professional of radiology, perform quality
control testing of these instruments in relation to the most recent norm of National Commission
of nuclear Energy (CNEN-NN 3:05) in Brazil, that is also in according to the international
standards and reference values established during acceptance testing of these instruments in a
nuclear medicine service. For this, was made a review of specific literature and the use of
barium, cobalt and cesium to the tests in a nuclear medicine service of the state of Pernambuco
in Brazil. The obtained results of the specific tests utilized to verify the correct working of the
dose calibrators show coherency with the resolutions of the CNEN-NN 3:05 and are also in
agreement with the international standards to that the measurement of activities be made with
accurate results and thereby contribute to the proper functioning of nuclear medicine service.
