摘要:
A method for assessing an alpha particle emission potential of a metallic material. A metallic material is initially subjected to a secular equilibrium disruption process, such as melting and/or refining, to disrupt the secular equilibrium of the radioactive decay of one or more target parent isotopes in the material. A sample of the material is treated to diffuse target decay isotopes within the sample such that the measured alpha particle emission directly corresponds to the concentration or number of target decay isotope atoms within the entirety of the sample, enabling the concentration of target decay isotopes in the sample to be determined. The concentration of target parent isotopes in the material may then be determined from the concentration of target decay isotopes and time elapsed from the secular equilibrium disruption process, and may be used to determine a maximum alpha particle emission that the metallic material will exhibit.
