Paragraph 1 I1

Northern Ireland

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) provided that—

(i)

the apparatus is of a type approved—

by the Great Britain Executive in accordance with paragraph 1(c) of Schedule 1 to the Great Britain Regulations;

(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 1???mSvh⁻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 chief inspector;

(d)

the operation of any electrical apparatus to which these Regulations apply other than apparatus referred to in sub-paragraph (e) provided that—

by the Executive; or

(bb)

by the Great Britain Executive in accordance with paragraph 1(d) of Schedule 1 to the Great Britain Regulations; and

(ii)

the apparatus does not under normal operating conditions cause a dose rate of more than 1mSvh⁻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 1mSvh–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 chief inspector has declared not to be subject to further control.
