AbstractAbstract
[en] The high sensibility of phosphor plates of digital radiography technique limits the use of common sources used by the conventional radiography. Paradoxically this is the greatest safety advantage of this technique because leads to the use of low activity sources. This article explains the benefits that come from the use of Ytterbium169 source of low activity (2 Ci) for weld quality control during a unit shutdown in one of PETROBRAS's refineries (REPLAN)
