clearance material if:
 (a) the material is in solid form; and
 (b) the total of the results of dividing the activity concentration of each nuclide of artificial origin in the material by the solid clearance value for the nuclide is not greater than one; and
 (c) the activity concentration of each nuclide of natural origin in the material is not greater than the level for the nuclide set out in in Table I.3 in Schedule I to GSR Part 3.
 (8) The solid clearance value, for a nuclide in controlled material, is:
 (a) if the weight of the controlled material exceeds 1 tonne and Table I.2 in Schedule I to GSR Part 3 sets out an activity concentration level for the nuclide—that activity concentration level; or
 (b) otherwise—the activity concentration level for the nuclide set out in Table I.1 in Schedule I to GSR Part 3.
 (9) For the purposes of dividing the activity concentration of a nuclide by the solid clearance value for the nuclide in accordance with paragraph (7)(b), the activity concentration of the nuclide is taken to be nil if:
 (a) all of the following apply:
 (i) the solid clearance value is an activity concentration level set out in Table I.2 in Schedule I to GSR Part 3;
 (ii) the nuclide is a progeny nuclide mentioned in note a to that table;
 (iii) the nuclide is included in secular equilibrium with the corresponding parent nuclide mentioned in that note; or
 (b) all of the following apply:
 (i) the solid clearance value is an activity concentration level set out in Table I.1 in Schedule I to GSR Part 3;
 (ii) the nuclide is a progeny nuclide mentioned in note b to that table;
 (iii) the nuclide is included in secular equilibrium with the corresponding parent nuclide mentioned in that note.
