* Current reaching the target disc passing through a 12 mm-diameter collimator. The current hitting the 6 mm-diameter pellet located at the center of the disc is approximately 1/4, depending on the centering of the beam that has a quasi-gaussian shape. ** QC done with DOTANOC (HPLC) method. † single measurement performed.
