Radiation environment at ISOL target station of rare isotope facility

Next-generation exotic beam facilities will offer several approaches to produce rare isotopes far from stability. One approach is Isotope Separation On-line, ISOL, which is the isotope production by interactions of light ion beams with heavy nuclei of targets. A pre-conceptual design of an ISOL target station was done as part of the research and development work for the Rare Isotope Accelerator, RIA. This report summarizes results of radiation calculations for the RIA ISOL target station. This includes radiation effects such as prompt radiation at the target station and from neutron sky-shine, activation of ground water, air, and components.
