ICRP Publication 101a: Assessing Dose of the Representative Person for the Purpose of the Radiation Protection of the Public
3.1. Definition of the representative person
(57) Dose to the public must be estimated using environmental concentrations or exposure rates and appropriate habit data. Therefore, for the purpose of protection of the public, it is necessary to define a person to be used for determining compliance with the dose constraint. This is the representative person. This individual, who will almost always be a hypothetical construct, receives a dose that is representative of the more highly exposed individuals in the population. The representative person is equivalent to, and replaces, the average member of the critical group recommended previously by the Commission (ICRP, 1985).
(58) In considering dose to the representative person, a number of factors should be taken into account: (1) the dose assessment must address all relevant pathways of exposure; (2) the dose assessment must consider spatial distribution of radionuclides to ensure that the individuals receiving the higher exposures are included in the assessment; (3) habit data should be based on the population exposed and must be reasonable, sustainable, and homogeneous; and (4) appropriate dose coefficients have to be applied to specific age categories. Once these factors are taken into account, and depending on the assessment approach employed (deterministic, probabilistic, or a mixture of these), the representative person is identified and used to determine compliance. Additional elaboration follows on each of these factors.
