Nuclear implantation of the cyclotron produced 7Be isotope was used for labeling of plastic and other materials that cannot be activated in nuclear wear measurements . In our experiments boron of natural composition was used in the form of a NiBSi metallic-glass foil as implantation target through the natB(p, x) 7Be nuclear reactions . Kapton (C 22H 10O 5N 2) and beryllium targets are also suitable by using a 3He beam [through 12C( 3He,2α) 7Be and 9Be( 3He, αn) 7Be reactions, respectively] to produce a high flux of radioactive 7Be in order to implant a very thin surface layer of the secondary target. The chosen secondary target should have a composition which does not contain elements which can be activated by the bombarding beam. This condition was controlled separately by the bombardment with the same beam. This control-irradiation is also useful to make corrections for possible interferences. Based on our early and recent experiences we have chosen Be as implantation target, having the most proper conditions for nuclear implantation.
