"integral_wrt_time_of_radioactivity_concentration_of_99Mo_in_air"@en . . . "The phrase \"integral_wrt_X_of_Y\" means int Y dX. 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. \"Mo\" means the element \"molybdenum\" and \"99Mo\" is the isotope \"molybdenum-99\" with a half-life of 2.78e+00 days."@en . .
