Resumo: | This work presents the preliminary activity measurements of 192Ir solid sources, applied in industrial gammagraphy, produced by the Sealed Sources Laboratory in the Radiation Technology Center (CTR) at IPEN-CNEN/SP. The pellets' activity measurements were carried out with a well-type ionization chamber developed at CTR. The chamber current-voltage response was studied as a function of 192Ir activities ranging from 27 GBq (0.75 Ci) to 4.1 TBq (110 Ci), under constant geometrical conditions. The results obtained have shown both the linearity of the ionization current and the absence of appreciable recombination or diffusion losses. |
