Description

The sum-peak method was used to obtain the absolute activity value for the 60Co, 65Zn e 22Na radioisotopes. Three HPGe detectors were used, being a planar, a coaxial and well type. The values of the activity obtained by sum-peak method are consistent, with values of uncertainty less 0.5% to for all radioisotopes considering k = 1. LNMRI has introduced a new Calibration System that uses a HPGE type well detector. Thus, a comparative study was made between the electronics available at the time of conception of the method and the one currently used. (paper)
