The US NRC Radiation Source Regulatory Partnership (RSRP) delivered a virtual workshop on “Design and Shielding Calculation for Linear Accelerators” for the regulatory authorities of Mauritius and Rwanda on January 19-20, 2022. The workshop, conducted in two sessions of about 4 hours each, provided an overview of basic concepts such as workload, occupancy and use factors, half and tenth value layers (which are important considerations in designing shielding), primary and secondary barriers, neutron dose, and the application of the time average and instant dose rates. The group also participated in several exercises demonstrating the application of the practical principles to determine primary and secondary barrier thicknesses. Six participants attended the seminar.
