SCHEDULE 1Work not required to be notified under regulation 5
1
Work with ionising radiation is not required to be notified in accordance with regulation 5 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 1 of Schedule 7 (for artificial radionuclides and naturally occurring radionuclides which are processed for their radioactive, fissile or fertile properties) or column 2 of Part 2 of Schedule 7 (for naturally occurring radionuclides which are not processed for their radioactive, fissile or fertile properties);
b
where the quantity of radioactive substance involved does not exceed the quantity specified in column 3 of Part 1 of Schedule 7 (for artificial radionuclides and naturally occurring radionuclides which are processed for their radioactive, fissile or fertile properties) or column 3 of Part 2 of Schedule 7 (for naturally occurring radionuclides which are not processed for their radioactive, fissile or fertile properties);
c
where the concentration of activity per unit mass or quantity of a radioactive substance does not exceed values which may be approved by the Executive for specific types of work and where such work satisfies the exemption criteria set out in paragraphs 2 and 3 below;
d
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—
aa
by the Executive; or
bb
by the Great Britain Executive in accordance with paragraph 1(d) 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 that 1 µSvh-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;
e
the operation of any electrical apparatus to which these Regulations apply other than apparatus referred to in sub-paragraph (f) provided that—
i
the apparatus is of a type approved—
aa
by the Executive; or
bb
by the Great Britain Executive in accordance with paragraph 1(e) 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 1 µSvh-1 at a distance of 0.1m from any accessible surface;
f
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 1 µSvh-1 at a distance of 0.1m from any accessible surface; or
g
where the work involves contaminated material resulting from authorised releases which the chief inspector has declared not to be subject to further control.
2
The criteria for the exemption from notification of work with ionising radiation are as follows:
a
the radiological risks to individuals caused by such work are sufficiently low, as to be of no regulatory concern;
b
work of such type has been found to be justified; and
c
such work is inherently safe.
3
Work with ionising radiation only meets the requirements of paragraph 2(a) if—
a
in relation to an employee, the effective dose caused by such work does not exceed 1 mSv in a calendar year; and
b
in relation to any other person, the following requirements are met in all circumstances where it is reasonably practicable to do so—
i
the effective dose caused by such work from radionuclides which are not naturally occurring radionuclides does not exceed 10 µSv in a calendar year; and
ii
the effective dose caused by such work from naturally occurring radionuclides does not exceed 1 mSv in a calendar year.
4
In paragraph 2(b), “found to be justified” has the meaning given by regulation 4(4) of the Justification of Practices Involving Ionising Radiation Regulations 200427.
5
In this Schedule, “the chief inspector” has the meaning assigned to it by section 47(1) of the Radioactive Substances Act 199328.
