1.Member States shall ensure that arrangements are made for the estimation of doses to members of the public from authorised practices. The extent of such arrangements shall be proportionate to the exposure risk involved.
2.Member States shall ensure the identification of practices for which an assessment of doses to members of the public shall be carried out. Member States shall specify those practices for which this assessment needs to be carried out in a realistic way and those for which a screening assessment is sufficient.
3.For the realistic assessment of doses to the members of the public, the competent authority shall:
(a)decide on a reasonable extent of surveys to be conducted and information to be taken into account in order to identify the representative person, taking into account the effective pathways for transmission of the radioactive substances;
(b)decide on a reasonable frequency of monitoring of the relevant parameters as determined in point (a);
(c)ensure that the estimates of doses to the representative person include:
assessment of the doses due to external radiation, indicating, where appropriate, the type of the radiation in question;
assessment of the intake of radionuclides, indicating the nature of the radionuclides and, where necessary, their physical and chemical states, and determination of the activity concentrations of these radionuclides in food and drinking water or other relevant environmental media;
assessment of the doses that the representative person, as identified in point (a), is liable to receive;
(d)require records to be kept and be made available on request to all stakeholders relating to measurements of external exposure and contamination, estimates of intakes of radionuclides, and the results of the assessment of the doses received by the representative person.
