(ii) a mixture of radionuclides the sum of the relative activities of which does not exceed 1; or
(b) either—
(i) a radionuclide at a concentration not exceeding the concentration set for radionuclides in the group in which it appears in the table in clause 3 of Schedule 1; or

(ii) the radioactive material is not contained in an article the use of which would require it to be carried by any person, or to be at a distance of less than 300 millimetres from any person; or
(b) the radioactive material contains a radionuclide, or a mixture of radionuclides, the activity of which does not exceed 0.1 of the activity specified in the said subclause (1)(a) or 3 kilobecquerels, whichever is the greater.
(3) Nothing in section 12 or section 13(1) of the Act, or in these regulations, shall apply to the sale, import, export, storage, transport otherwise than for the purposes of exportation, or use of any article of a kind described in the first column of Schedule 3 of these regulations if and so long as the article conforms with the conditions set out in the second column of that schedule in relation thereto:
