Artigo IPEN-doc 20135 A study about the measurement method of the homogeneity of radioactivity along an iridium-192 wire used in brachytherapy2014 - COSTA, OSVALDO L.; CALVO, WILSON A.P.; ZEITUNI, CARLOS A.; ROSTELATO, MARIA E.C.M.; MOURA, JOAO A.; FEHER, ANSELMO; SOUZA, CARLA D.; SOMESSARI, SAMIR L.The Nuclear and Energy Research Institute has produced, since 1998, iridium-192 wires used in low dose rate brachytherapy. In the paper the authors studied the influence of wire profile on the homogeneity distribution of radioactivity of iridium-192 along the wire. The authors propose the improvements in the quality control procedure that will provide more accurate measurement data and suggest changes in control devices.
