Regulations 6(1) and 13(3)
1. Work with ionising radiation shall not be required to be notified in accordance with regulation 6 when the only such work being carried out is in one or more of the following categories—
(a)where the concentration of activity per unit mass of a radioactive substance does not exceed the concentration specified in column 2 of Part I of Schedule 8;
(b)where the quantity of radioactive substance involved does not exceed the quantity specified in column 3 of Part I of Schedule 8;
(c)where apparatus contains radioactive substances in a quantity exceeding the values specified in sub-paragraphs (a) and (b) above provided that—
(i)the apparatus is of a type approved by the Executive;
(ii)the apparatus is constructed in the form of a sealed source;
(iii)the apparatus does not under normal operating conditions cause a dose rate of more than 1μSvh−1 at a distance of 0.1m from any accessible surface; and
(iv)conditions for the disposal of the apparatus have been specified by the appropriate Agency;
(d)the operation of any electrical apparatus to which these Regulations apply other than apparatus referred to in sub-paragraph (e) below provided that—
(i)the apparatus is of a type approved by the Executive; and
(ii)the apparatus does not under normal operating conditions cause a dose rate of more than 1μSvh−1 at a distance of 0.1m from any accessible surface;
(e)the operation of—
(i)any cathode ray tube intended for the display of visual images; or
(ii)any other electrical apparatus operating at a potential difference not exceeding 30kV,
provided that the operation of the tube or apparatus does not under normal operating conditions cause a dose rate of more than 1μSvh−1 at a distance of 0.1m from any accessible surface;
(f)where the work involves material contaminated with radioactive substances resulting from authorised releases which the appropriate Agency has declared not to be subject to further control.
2. In this Schedule, “the appropriate Agency” has the meaning assigned to it by section 47(1) of the Radioactive Substances Act 1993(1).
1993 c. 12; section 47 was amended by the Environment Act 1995 (c. 25), Schedule 22, paragraph 227.
