A compartment model has been developed to predict activity concentrations in fruit following deposition of radionuclides from both accidental and continuous releases of radioactivity to the atmosphere. This model considers the major fruit species grown in the UK.

The important routes of contamination for the major fruit species have been identified as a basis for determining the modelling approach following a review of experimental data and modelling approaches. A robust approach is adopted, reflecting the availability of information on radionuclide transfer to fruit. Where necessary, the modelling approaches adopted in foodchain models for other crops have been used to ensure that all potentially important transfer processes are taken into account.

This model replaces an earlier fruit model within the FARMLAND suite of foodchain models which was developed specifically for continuous release applications in 1995.
