A feasibility study regarding the production of radioactive carbon black and nanotubes has been performed by proton beam irradiation. Experimental and theoretical excitation functions of the nuclear reaction C-nat(p,x)Be-7 in the proton energy range 24-38 MeV are reported, with an acceptable agreement.
We have demonstrated that sufficient activities of Be-7 radioisotope can be produced in carbon black and nanotube that would facilitate studies of their possible impact on human and environment.
