"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. \"Xe\" means the element \"xenon\" and \"133mXe\" is the metastable state of the isotope \"xenon-133\" with a half-life of 2.26e+00 days."@en . . .
