Feasibility study of production of radioactive carbon black or carbon nanotubes in cyclotron facilities for nanobioscience applications

Abstract

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 natC(p,x)7Be in the proton energy range 24–38MeV are reported, with an acceptable agreement. We have demonstrated that sufficient activities of 7Be radioisotope can be produced in carbon black and nanotube that would facilitate studies of their possible impact on human and environment.
