skos:definition "A group of 'members of the public' which is reasonably homogeneous with <br/>
respect to its 'exposure' for a given 'radiation' 'source' and is typical of individuals <br/>receiving the highest 'effective dose' or 'equivalent dose' (as applicable) from the <br/>given 'source'. (From Ref. [1].)<br/>
The deletion from this definition of the phrase “and given 'exposure pathway'” <br/>implies that there will not be a number of 'critical groups' for a given 'source'. <br/>Some non-IAEA publications, notably those of the International Commission <br/>on Radiological Protection [12], use a definition of 'critical group' that makes <br/>no such reference to a given 'exposure pathway', implying that there is only one <br/>'critical group' for a given 'source', namely the one with the highest total <br/>'exposure' from all 'exposure pathways'. <br/>Application of the term to 'potential exposures', such as those that may occur in <br/>the future as a result of 'radioactive waste disposal', is complicated by the facts <br/>that both the 'dose' (if it occurs) and the probability of receiving the 'dose' are <br/>relevant, and that these two parameters are essentially independent of one <br/>another. Hence, a group can be homogeneous with respect to 'dose' but not <br/>'risk', and, more importantly, vice versa. A commonly adopted solution is to <br/>define a 'critical group' — often a 'hypothetical critical group' — that is <br/>
reasonably homogeneous with respect to 'risk' and is typical of those people <br/>who might be subject to the highest 'risk'.<br/>
<i><b>hypothetical critical group.</b></i> A group of hypothetical individuals which is <br/>reasonably homogeneous with respect to the 'risk' to which its members <br/>are subject from a given 'radiation source', and is representative of the <br/>individuals likely to be most at 'risk' from the given 'source'.<br/>" (en)
