Technical noteMeasurement of depth distributions of 3H and 14C induced in concrete shielding of an electron accelerator facility

The estimation of radioactivity induced in concrete shielding is important for the decommissioning of accelerator facilities. Concentrations of 3H and 14C in the concrete shielding of an electron linear accelerator were measured, and the depth distributions of 3H, 14C and γ-ray emitters were discussed in relation to their formation reactions.
