    Table 7. Average Inactivation Factors (Decimal Reduction) Estimated (This table indicates the average extent of inactivation that particles seen in the surf zone have undergone. Most notably it shows for effluent and the highest inactivation scenarios ( 3 MJ.m-2 ) that they had only been reduced by a factor of ca 1 log10 unit indicating at least for those particles detected, the main protection was provided by dilution. )

    Table 8. Average of Total Reduction Seen In Each Scenario (This table indicated the average total reduction of the particles detected for different scenarios. Solar radiation can be seen to be more effective in summer than winter most clearly with the 15 MJ.m-2 scenario. The apparently greater reduction for this scenario compared to the 3 MJ.m-2 scenario is due to the more particles being completely eliminated in the latter case from the model (i.e. pathogens completely inactivated)).
