The data variable should have an axis for X specifying the limits of the integral as bounds. 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. \"Cd\" means the element \"cadmium\" and \"115Cd\" is the isotope \"cadmium-115\" with a half-life of 2.23e+00 days."@en . . .
