Abstract

Although the estimation of ¹⁴C radioactivity is very important from a radiation safety viewpoint at high-intensity and high-energy accelerator facilities, it is very difficult, since there is little information concerning the production cross sections by high-energy nuclear reactions. In this work, the ¹⁴C production cross section was measured for the nuclear spallation reaction of aluminum with 12-GeV protons. The chemical separation method of ¹⁴C was also studied.
