Appendix III

The Ionising Radiation (Medical Exposure) Regulations 2000 with the Ionising Radiation (Medical Exposure) (Amendment) Regulations 2006 and the Ionising Radiation (Medical Exposure) (Amendment) Regulations 20111

These Regulations, together with the Ionising Radiations Regulations 1999 (S.I. 1999/3232) partially implement, as respects Great Britain, Council Directive 97/43/Euratom (OJ No. L180, 9.7.97, p. 22) laying down basic measures for the health protection of individuals against dangers of ionizing radiation in relation to medical exposure. The regulations impose duties on those responsible for administering ionizing radiation to protect persons undergoing medical exposure whether as part of their own medical diagnosis or treatment or as part of occupational health surveillance, health screening, voluntary participation in research or medico-legal procedures.

They replaced The Ionising Radiation (Protection of Persons Undergoing Medical Examination or Treatment) Regulations 1988.

(a) complies with the provisions of regulation 11(1); and

(b) undertakes continuing education and training after qualification including, in the case of clinical use of new techniques, training related to these techniques and the relevant radiation protection requirements; or

(c) where the employer is concurrently practitioner or operator, he shall himself ensure that he undertakes such continuing education and training as may be appropriate.

5. Where the employer knows or has reason to believe that an incident has or may have occurred in which a person, while undergoing a medical exposure was, otherwise than as a result of a malfunction or defect in equipment, exposed to ionizing radiation to an extent much greater than intended, he shall make an immediate preliminary investigation of the incident and, unless that investigation shows beyond a reasonable doubt that no such overexposure has occurred, he shall forthwith notify the appropriate authority and make or arrange for a detailed investigation of the circumstances of the exposure and an assessment of the dose received.

6. The employer shall undertake appropriate reviews whenever diagnostic reference levels are consistently exceeded and ensure that corrective action is taken where appropriate.

5 Duties of the practitioner, operator and referrer

5. The referrer shall supply the practitioner with sufficient medical data (such as previous diagnostic information or medical records) relevant to the medical exposure requested by the referrer to enable the practitioner to decide on whether there is a sufficient net benefit as required by regulation 6(1)(a).

6. The practitioner and the operator shall cooperate, regarding practical aspects, with other specialists and staff involved in a medical exposure, as appropriate.

7. For the avoidance of doubt, where a person acts as employer, referrer, practitioner and operator concurrently (or in any combination of these roles) he shall comply with all the duties placed on employers, referrers, practitioners or operators under these Regulations accordingly.

6 Justification of Individual Medical Exposures

1. No person shall carry out a medical exposure unless:

(a) it has been justified by the practitioner as showing a sufficient net benefit giving appropriate weight to the matters set out in paragraph (2); and

(b) it has been authorized by the practitioner or, where paragraph (5) applies, the operator; and

(c) in the case of a medical or biomedical exposure as referred to in regulation 3(d), it has been approved by an ethics committee; and

(d) in the case of an exposure falling within regulation 3(e), it complies with the employer's procedures for such exposures; and

(e) in the case of a female of child-bearing age, he has enquired whether she is pregnant or breast feeding, if relevant.

2. The matters referred to in paragraph (1)(a) are:

(a) the specific objectives of the exposure and the characteristics of the individual involved

(b) the total potential diagnostic or therapeutic benefits, including the direct health benefits to the individual and the benefits to society, of the exposure

(c) the individual detriment that the exposure may cause and

(d) the efficacy, benefits and risk of available alternative techniques having the same objective but involving no or less exposure to ionizing radiation.

3. In considering the weight to be given to the matters referred to in paragraph (2), the practitioner justifying an exposure pursuant to paragraph (1)(a) shall pay special attention to:

(a) exposures on medico-legal grounds

(b) exposures that have no direct health benefit for the individuals undergoing the exposure and

(c) the urgency of the exposure, where appropriate, in cases involving:

(i) a female where pregnancy cannot be excluded, in particular if abdominal and pelvic regions are involved, taking into account the exposure of both the expectant mother and the unborn child and

(ii) a female who is breast feeding and who undergoes a nuclear medicine exposure, taking into account the exposure of both the female and the child.

4. In deciding whether to justify an exposure under paragraph (1)(a) the practitioner shall take account of any data supplied by the referrer pursuant to regulation 5(5) and shall consider such data in order to avoid unnecessary exposure.

5. Where it is not practicable for the practitioner to authorize an exposure as required by paragraph (1)(b), the operator shall do so in accordance with guidelines issued by the practitioner.

7 Optimization

1. In relation to all medical exposures to which these Regulations apply except radiotherapeutic procedures, the practitioner and the operator, to the extent of their respective involvement in a medical exposure, shall ensure that doses arising from the exposure are kept as low as reasonably practicable consistent with the intended purpose.

2. In relation to all medical exposures for radiotherapeutic purposes the practitioner shall ensure that exposures of target volumes are individually planned, taking into account that doses of non-target volumes and tissues shall be as low as reasonably practicable and consistent with the intended radiotherapeutic purpose of the exposure.

3. Without prejudice to paragraphs (1) and (2), the operator shall select equipment and methods to ensure that for each medical exposure the dose of ionizing radiation to the individual undergoing the exposure is as low as reasonably practicable and consistent with the intended diagnostic or therapeutic purpose and in doing so shall pay special attention to:

(a) quality assurance

(b) assessment of patient dose or administered activity and

(c) adherence to diagnostic reference levels for radiodiagnostic examinations falling within regulation 3(a), (b), (c) and (e) as set out in the employer's procedures.

5. In the case of patients undergoing treatment or diagnosis with radioactive medicinal products, the employer's procedures shall provide that, where appropriate, written instructions and information are provided to:

(a) the patient, where he has capacity to consent to the treatment or diagnostic procedure or

(b) where the patient is a child who lacks capacity so to consent, the person with parental responsibility for the child or

(c) where the patient is an adult who lacks capacity so to consent, the person who appears to the practitioner to be the most appropriate person.

6. The instructions and information referred to in paragraph (5) shall:

(a) specify how doses resulting from the patient's exposure can be restricted as far as reasonably possible so as to protect persons in contact with the patient

(b) set out the risks associated with ionizing radiation and

(c) be provided to the patient or other person specified in paragraph (5) as appropriate prior to the patient leaving the hospital or other place where the medical exposure was carried out.

7. In complying with the obligations under this regulation, the practitioner and the operator shall pay special attention to:

(a) the need to keep doses arising from medico-legal exposures as low as reasonably practicable

(b) medical exposures of children

(c) medical exposures as part of a health screening programme

(d) medical exposures involving high doses to the patient

(e) where appropriate, females in whom pregnancy cannot be excluded and who are undergoing a medical exposure, in particular if abdominal and pelvic regions are involved, taking into account the exposure of both the expectant mother and the unborn child and
