activité totale

CONT: Table 3 shows the relative proportions of the different classes of low-level radioactive wastes .... It is noteworthy that mine and mill tailings dominate in both volume and specific activity. Figure 6 shows the ""other"" category of Figure 5 again, this time by volume and total activity.
OBS: For a material containing a specified radionuclide, the ratio of the activity of that radionuclide and its short-lived daughter products to the total activity of the material is called the ""radioactive purity"".
