abstract = {At sites with powerful particle accelerators, the problem
of groundwater activation by direct neutron radiation
arises. Licensing of particle accelerators requires evidence
that groundwater activation is within the legal limits and
thus will not endanger workers, the public, or the
environment.In this study we focus on the following
radionuclides: C-14, Ca-41, Ca-45, Cl-36, Co-55, Co-57,
Co-60, H-3, Mn-54, Na-24, P-32, S-35, Si-32, and V-50. The
conventional approach for calculating activation of soil and
groundwater is described and utilized for a fictive 5-MW
proton accelerator at Julich, Germany, with a beam loss of 1
W.m(-1). An updated overview of partition co-efficients for
relevant radionuclides in sand, clay, loam, and organic
soils is presented. Based on the two aforementioned methods,
groundwater activation is estimated with a simplified
homogeneous groundwater transport model. The results
indicate H-3, C-14, and Cl-36 as the most relevant
radionuclides concerning the resultant activity
concentrations and estimated dose rates at the site
boundary. For this fictive test case, the site boundary is
located a distance 250 m downstream of the accelerator,
which leads to acceptable risk for the public, given the
legal standards.},
