- (1) Every employer who designates any area as a controlled or
supervised area shall ensure that any such designated area is adequately
described in local rules and that -
(a) in the case of any controlled area -
(i) the area is physically demarcated or, where this is not
reasonably practicable, delineated by some other suitable means;
and
(ii) suitable and sufficient signs are displayed in
suitable positions indicating that the area is a controlled area, the
nature of the radiation
sources in that area and the risks arising from such sources;
and
(b) in the case of any supervised area, suitable and sufficient signs
giving warning of the supervised area are displayed, where appropriate,
in suitable positions indicating the nature of the radiation sources and the risks
arising from such sources.
(2) The employer who has designated an area as
a controlled area shall not permit any employee or other person to enter
or remain in such an area unless that employee or other
person -
(a) being a person other than an outside worker, is a classified
person;
(b) being an outside worker, is a classified person in
respect of whom the employer has taken all reasonable steps to ensure
that the person -
(i) is subject to individual dose assessment pursuant to regulation 21;
(ii) has been
provided with and has been trained to use any personal protective
equipment that may be necessary pursuant to regulation 8(2)(c);
(iii) has
received any specific training required pursuant to regulation 14; and
(iv) has
been certified fit for the work with ionising radiation which he is to carry out
pursuant to regulation 24;
or
(c) not being a classified person, enters or remains in the area in
accordance with suitable written arrangements for the purpose of
ensuring that -
(i) in the case of an employee aged 18 years or over, he does not
receive in any calendar year a cumulative dose of ionising radiation which would require that
employee to be designated as a classified person; or
(ii) in
the case of any other person, he does not receive in any calendar year
a dose of ionising radiation exceeding any relevant
dose limit.
(3) An employer who has designated an area as a
controlled area shall not permit a person to enter or remain in such area
in accordance with the written arrangements under paragraph (2)(c), unless
he can demonstrate, by personal dose monitoring or other suitable
measurements, that the doses are
restricted in accordance with that
sub-paragraph.
(4) An employer who has
designated an area as a controlled area shall, in relation to an outside
worker, ensure that -
(a) the outside worker is subject to arrangements for estimating the
dose of ionising radiation he receives whilst in the
controlled area;
(b) as soon as is reasonably practicable after
the services carried out by that outside worker in that controlled area
are completed, an estimate of the dose received by that worker is
entered into his radiation
passbook; and
(c) when the radiation passbook of the outside
worker is in the possession of that employer, the passbook is made
available to that worker upon request.
(5) The employer who carries out the monitoring
or measurements pursuant to paragraph (3) shall keep the results of the
monitoring or measurements referred to in that paragraph for a period of
two years from the date they were recorded and shall, at the request of
the person to whom the monitoring or measurements relate and on reasonable
notice being given make the results available to that
person.
(6) In any case where there is a
significant risk of the spread of radioactive contamination from a
controlled area, the employer who has designated that area as a controlled
area shall make adequate arrangements to restrict, so far as is reasonably
practicable, the spread of such
contamination.
(7) Without prejudice to the
generality of paragraph (6), the arrangements required by that paragraph
shall, where appropriate, include -
(a) the provision of suitable and sufficient washing and changing
facilities for persons who enter or leave any controlled or supervised
area;
(b) the proper maintenance of such washing and changing
facilities;
(c) the prohibition of eating, drinking or smoking or
similar activity likely to result in the ingestion of a radioactive substance by any employee in a
controlled area; and
(d) the means for monitoring for
contamination any person, article or goods leaving a controlled
area.
