Contents
Purpose
This Directive lays down the general principles of the radiation protection of indivuals undergoing medical exposures and associated practices involving ionizing radiation.
The purpose of this Directive is to supplement Directive 80/836/Euratom on the basic safety standards as regards medical exposures.
Definitions
For the purpose of this Directive, the following terms have the meaning hereby assigned to them:
- audit: a systematic and independent examination to determine whether the measures taken and the related results comply with prescribed criteria;
- clinical responsibility: responsibility regarding individual medical exposures attributed to a practitioner, notably justification, optimization, clinical evaluation of the outcome, cooperation with other specialists and the staff as appropriate regarding practical aspects, obtaining information if appropriate of previous examinations, providing existing radiological information and/or records to other practitioners promptly, giving information on the risks of ionizing radiation to patients as appropriate;
- competent authorities: any authority responsible in a Member State for the application of any part of this Directive, or any body or bodies designated by the Member State for this purpose;
- exposure: process of being exposed to ionizing radiation;
- health detriment: clinically observable deleterious effects that are expressed in individuals or their descendants, the appearance of which is either immediate or delayed and, in the latter case, implies a probability rather than a certainty of appearance;
- health screening: a procedure using radiological installations for early diagnosis in asymptomatic population groups, also called mass screening;
- holder: any natural or legal person who has the legal responsibility under national law for the use and holding of a given radioligcal installation;
- medical physicist: an expert in radiation physics applied to medical exposures whose training and competence to act is recognized by the competent authorities and who, as appropriate, gives advice on patient dosimetry, on the development and use of complex techniques and equipment and on optimization, on quality assurance, including quality control, and on matters relating to radiation protection as defined in Article 3, as appropriate. This expert might also give advice on radiation protection aspects as regards workers and the public;
- medical radiological practice: each type of activity resulting in exposure to ionizing radiation for medical purpose;
- potential exposures: exposure with a probability of occurrence that can be estimated in advance for accidents and incidents, such as a failure of equipment, a misadministration, a human error or a computer failure;
- practical aspects: any aspect associated with the medical practice such as handling and use of radiological equipment, measurement of technical and physical parameters including radiation doses, calibration and maintenance of equipment, preparation and injection of radio-pharmaceuticals, medical informatics;
- practioner: a medical doctor, dentist or other health professional, who is entitled to take overall clinical responsibility for individual medical exposures in accordance with national legislation;
- prescriber: a medical doctor, dentist or other health professional, who is entitled to refer individuals for medical exposures, in accordance with national legislation;
- quality assurance: all those planned and systematic actions necessary to provide adequate confidence that a structure, system or component will perform satisfactorily in service. Satisfactory performance in service implies the optimum quality of the entire procedure. In the case of radiodiagnostic procedure, the consistent production of adequate diagnostic information with minimum exposure of both patients and personnel. In the case of a radiotherapeutic procedure optimum exposure of patients and minimum exposure of personnel;
- quality control: the set of operations (programming, coordinating, carrying out) intended to maintain or to improve quality. It covers monitoring, evaluation, and maintenance at optimum levels of all characteristics of performance that can be defined, measured, and controlled;
- radiological: pertaining to radiodiagnosis, radiotherapy and nuclear medicine;
- radiodiagnostic: pertaining to in vivo diagnostic nuclear medicine, diagnostic radiology and interventional radiology;
- radiotherapeutic: pertaining to therapeutic nuclear medicine and every other type of radiotherapy;
- reference level: a tool for optimization of radiation protection in medical radiodiagnostic practices by specifying dose levels and, in the case of radiopharmaceuticals levels of activity, for typical examinations for a standard sized patient, taking into account good practice regarding diagnostic and technical performance. An investigation may be needed if these levels are exceeded and corrective action should be taken, if appropriate.
Scope
1. This Directive shall apply to all medical exposures and associated practices:
(a) the exposure of individuals as part of their own medical diagnosis or treatment;
(b) the exposure of individuals as part of medico-legal, insurance or legal procedures;
(c) the exposure of individuals as part of health screening;
(d) the exposure of individuals knowingly and willingly helping (other than as part of their own occupation) in the support and comfort of patients undergoing medical diagnosis or treatment;
(e) the exposure of individuals in medical and biomedical research programmes.
2. This Directive shall not apply to the design and the placing on the market of medical devices covered by the Directive 93/42/EEC.
Justification
1. All individual medical exposures shall be justified taking into account the specific objectives of the exposure and the efficacy and availability of alternative techniques.
The prescriber and the practitioner will always check if previous diagnostic information or medical records relevant to the planned exposure are available and consult these data to avoid unnecessary examinations.
2. All new medical radiological practices shall be justified in advance by their potential benefits in relation to alternative practices having the same objective but not involving exposure to ionizing radiation and in relation to the health detriment they might cause; existing practices shall be reviewed whenever new, important evidence about their efficiency or consequences is acquired.
3. Member States shall take measures to avoid unnecessary proliferation of installations for radiodiagnostic and radiotherapeutic purposes.
4. Special attention shall be given for those exposures where there is no direct health benefit for the person undergoing the exposure and especially for exposures on medico-legal, insurance and legal grounds.
5. The prescriber as well as the practitioner shall be involved in the justification process, as the appropriate level.
6. Exposures for biomedical and medical research shall be examined by an officially approved ethics committee and/or the competent authorities, taking into account the principles set out by recommendation R(90)3 of the Committee of Ministers of the Council of Europe.
7. In the case of fluoroscopy, examinations without image intensification are not justified and shall therefore be prohibited and examinations without an automatic dose rate control shall be limited to exceptional circumstances.
Optimization
1. All medical exposures for radiodiagnostic purposes shall be kept as low as reasonably achievable consistent with obtaining the required diagnostic information, taking into account economic and social factors. Member States shall promote the establishment and use of reference levels for medical exposures and shall ensure, on the basis of European reference levels where available, the availability of guidance for this purpose.
2. For radiotherapeutic purposes, exposures of target tissues shall be individually planned; exposures of non target tissues shall be as low as reasonably achievable, without underexposing the target tissues.
3. Written guidelines for every type of standard radiological practice shall be established for each item of radiological equipment.
4. The optimization process shall include selection of equipment and both acceptance testing before the first use of the installation for clinical purposes, and thereafter performance testing on a regular basis, and after any major maintenance procedure.
5. In radiotherapeutic practices, a medical physicist shall be closely involved. In diagnostic nuclear medicine practices, a medical physicist shall be involved as appropriate. For other radiodiagnostic practices, a medical physicist shall be available for consultation on optimization and quality assurance, including quality control, as appropriate, and also to give advice on matters relating to radiation protection concerning medical exposures, as required.
6. Member States shall ensure that for each biomedical and medical research project involving healthy volunteers, a maximum individual dose level is established. These volunteers will be informed about the risks of exposure to ionizing radiation.
7. In the special case of patients, who voluntarily accept to undergo an experimental therapeutic or diagnostic practice, optimum dose levels should be established on an individual basis by the practitioner.
Responsibilities
1. Member States shall ensure that any medical exposure is effected under the clinical responsibility of a practitioner.
2. The practical aspects for the procedure or part of it may be delegated, as appropriate, to one or more individuals entitled by the competent authorities to act in this respect in the relevant field of specialization, such as medical physics, radiation and nuclear medicine technology, medical-nuclear engineering, radiopharmacy, radiography and medical informatics.
3. Member States shall lay down procedures to determine responsibilities in case of medico-legal, insurance or legal examinations.
