Paragraph 2 Interpretation: radioactive material
In this Schedule, “radioactive material” means anything which, not being waste, is either a substance to which this sub-paragraph applies or an article made wholly or partly from, or incorporating, such a substance.
Sub-paragraph (1) applies to any substance which—
contains an element specified in the first column of the table in sub-paragraph (4), in such a proportion that the number of becquerels of that element contained in the substance, divided by the number of grams which the substance weighs, is a number greater than that specified in relation to that element in the appropriate column of that table; or
possesses radioactivity which is wholly or partly attributable to a process of nuclear fission or other process of subjecting a substance to bombardment by neutrons or to ionising radiations, not being a process occurring in the course of nature, or in consequence of the disposal of radioactive waste, or by way of contamination in the course of the application of a process to some other substance.
In sub-paragraph (2)(a), “the appropriate column” means—
in relation to a solid substance, the second column;
in relation to a liquid substance, the third column;
in relation to a substance which is a gas or vapour, the fourth column.
The table referred to in sub-paragraph (2)(a)—
