Screening Approach to the Activation of Soil and Contamination of Groundwater at Linear Proton Accelerator Sites

The activation of soil and the contamination of groundwater at proton accelerator sites with the radionuclides 3H and 22Na are estimated with a Monte-Carlo calculation and a conservative soil- and ground water model.
The obtained radionuclide concentrations show that the underground environment of future accelerators must be adequately protected against a migration of activation products.
This study is of particular importance for the proton driver accelerator in the planned EURISOL facility.
