FS430769 Terrestrial modelling for radiological risk assessments (PRISM) and renewal of AMBER software licence

The FSA provides advice to the UK environment agencies on food safety implications of both routine and emergency discharges of radioactive waste to the environment. This is primarily done by undertaking radiological dose (risk) assessments. The FSA uses bespoke software models to predict possible transfer of these discharges through the environment and into the food chain. The outputs from these modelling tools enable the FSA to provide advice on possible effects on food for both routine operations, and during incidents. Probabilistic Implementation of SPADE (Statistical Program to Assess Dietary Exposure) Models (PRISM) is a probabilistic model that allows the prediction of the transfer of deposited aerial radioactive material into food products in the terrestrial environment.
