Abstract

This paper summarises the current methodology used in England for assessing the impact on the foodchain of radioactive waste discharges, the improvements currently being implemented, and describes the supporting R&D. Research on terrestrial pathways is focused on gaining a better understanding of the interception of radioactivity by crop surfaces, the dynamic behaviour of mobile contaminants and a concerted programme to improve the modelling of the uptake of radioactivity into fruit Research on aquatic pathways includes development of near-field dispersion models, gut uptake studies, and the influence of chemical processes on radionuclide uptake by sediments and colloids.
