Estimates of population doses

assessment of the doses due to external radiation, indicating, where appropriate, the quality of the radiation in question,

ensure, taking into account the radiological risks, that the estimates of the population doses include:

For the estimation of effective and equivalent doses the values and relationships referred to in this Title shall be used.

the results of workplace monitoring used to assess individual doses where necessary.

the contracts will in particular specify the quantities of antigen doses necessary, taking account of the requirements estimated in the context of the

The results of these measurements shall be recorded and shall be used, if necessary, for estimating individual doses, as provided for in Article 25.

a record of the exposures measured or estimated, as the case may be, of individual doses pursuant to Articles 12, 25, 26 and 27;

For external radiation, the values and relationships given in Annex II shall be used to estimate the relevant effective and equivalent doses;

assessment of the doses that the reference groups of the population are liable to receive and specification of the characteristics of these groups.

The dosimetry estimates were based on a rat biodistribution study and the calculations were effected in accordance with MIRD/ ICRP 60 recommendations.

Each Member State shall require that workers have access at their request to the results of their individual monitoring, including the results of measurements which may have been used in estimating them, or of the assessments of their doses made as a result of workplace measurements.

The dosimetry estimates were based on clinical biodistribution studies using methods developed for radiation dose calculations by the Medical Internal Radiation Dose (MIRD) Committee of the Society of Nuclear Medicine.

For internal exposure from a radionuclide or from a mixture of radionuclides, the values and relationships given in Annexes II and III may be used to estimate the effective doses.

ensure that dose estimates from practices referred to in Article 44 are made as realistic as possible for the population as a whole and for reference groups of the population in all places where such groups may occur;

classification of workplaces into different areas, where appropriate, by reference to an assessment of the expected annual doses and the probability and magnitude of potential exposures;

For each sample of tuberculin under test, an estimate of relative potency against the appropriate standard and its fiducial limits shall be made by statistical methods, using the diameters of the reactions and the logarithms of the doses as metameters.

Radiation dose estimates for bone and marrow assume that radioactivity is deposited on bone surfaces, in accordance with autoradiograms of bone samples taken from patients who received QUADRAMET.

require records to be kept relating to measurements of external exposure, estimates of intakes of radionuclides and radioactive contamination as well as the results of the assessment of the doses received by reference groups and by the population.

a body responsible for the calibration, reading or interpretation of individual monitoring devices, or for the measurement of radioactivity in the human body or in biological samples, or for assessment of doses, whose capacity to act in this respect is recognized by the competent authorities.

In cases where individual measurements are impossible or inadequate, the individual monitoring shall be based on an estimate arrived at either from individual measurements made on other exposed workers or from the results of the surveillance of the workplace provided for in Article 24.

Persons having the knowledge and training needed to carry out physical, technical or radiochemical tests enabling doses to be assessed, and to give advice in order to ensure effective protection of individuals and the correct operation of protective equipment, whose capacity to act as a qualified expert is recognized by the competent authorities.
