Improved modelling of radioactive metal behaviour in natural waters

What is it about?

We need to use models to examine what may happen to radioactive waste forms when they are disposed in underground repository (or in the case of accidental environmental contamination). This study uses known chemical relationships to calculate parameters that can be used in predictive models.

Why is it important?

Radioactive wastes, when placed in repository, may dissolved and interact with other components in water. Models allow prediction of how radioactive metals may behave in a range of scenarios. This work has introduced model binding parameters for aquatic environments for a range of radioactive metal forms, for the first time.
