Use of aileron for 'free grains- bound grains' mixed technique for the prostatic permanent implant

We realized a device called aileron which receives the bound grains after cut from a needle of transfer in the classic tip and to align the axis of this last one with the axis of the needle implanted Mick. Guaranteeing besides a better radiation protection, this aileron allowed us to find very low rates of irradiation of our personal dosemeters at least comparable to the rates previously raised in the exclusive free gains technique.
