The phrase \"wrt\" means \"with respect to\". \"Radioactivity\" means the number of radioactive decays of a material per second. \"Radioactivity concentration\" means radioactivity per unit volume of the medium. \"Nb\" means the element \"niobium\" and \"95Nb\" is the isotope \"niobium-95\" with a half-life of 3.52e+01 days."@en .
