Resumo
Quality assurance in whole-body measurement includes quality control with procedure descriptions,
detector calibrations, instrument control and evaluation internally or by outside persons. It is well know
that some or several characteristics can be affected when the detector has been used in different energy
radiation beams. A comparison and evaluation of the NaI(Tl) and HPGe based detector systems’
performances has been carried out at In Vivo Monitoring Laboratory of IPEN/CNEN-SP for measurements
of elements used in radiopharmacy (131I, 123I and 99mTc) in chest regions. Alderson Research Labs.
anthropomorphic phantom was used for the calibration. The concepts adopted in the HPS N13.30 Standard
and proposed in ISO documents for standardization were used for activity measurements. Results of this
comparison are presented together relative efficiencies and MDA values for all NaI(Tl) and HPGe based
detector systems involved.
