Results do not include the effects of ingrowth of long-lived daughter radionuclides. Sensitivity studies to show the effect of different assumptions about the exposed individual are presented in Appendix C, where specific doses for an adult, an infant (1 year old) and child (10 year old) are given for the different potential exposure pathways following a leachate spill to a surface water body. A comparison of the calculated specific doses for different age groups shows that for pathways associated with the consumption of fish and crops the greater consumption rates for adults outweigh the higher dose coefficients for infants and children. For the pathways associated with livestock and drinking water, the age group with the highest specific dose depends on the radionuclide, but in all cases the ratio of specific doses between age groups is less than a factor of 10. Only in the case of exposure through the consumption of contaminated soil are specific doses to infants and children higher than those to adults by a factor of more than 10, because of the greater consumption rates assumed for these age groups. 5.4.3 Aerosol pathway Specific doses calculated for workers and members of the public via the aerosol pathway are presented in Table 5.6. These calculations are based on the assumptions described in Section 4.1.8 and in Appendix A, and are presented as specific doses per hour of exposure to aerosols.
