Radiological capacities are based on a 3 mSv / year dose criterion. Results include doses arising from ingrowth of daughter radionuclides for 60 years. 6.3 Overall radiological capacity To illustrate the potential overall capacity of the ENRMF, waste stream data for the UKAEA Harwell Meashill Trenches (Table 2.6) has been used to calculate overall radiological capacities based on the groundwater and human intrusion pathways using the assumptions and dose criteria described above. The results presented in Tables 6.4 to 6.6 show that the calculated capacities for the groundwater and human intrusion pathways are very similar, in large part because of the different dose criteria applied. Table 6.6 also shows the contributions to the overall dose of the individual radionuclides. For the groundwater pathway, Pu-239 and Pu-240 are the key contributors to dose. In the case of human intrusion, Ra-226 is the principal contributor to dose.
