6. Irradiation- and temperature-induced phenomena
6.1 Concrete activation
Neutron irradiation of concrete produces secondary gamma radiation as a result of nuclear reactions on the constituent atoms. The emission of γ photons may occur concomitantly with neutron absorption ("n, γ" radiative capture), or deferred, by deactivation of the new nuclei formed if the latter are unstable. Depending on the nature of the nuclei involved, radioactive decay can take place over short periods (s, min, h), which can hinder operations, or over long periods (
