Sumario:At the LHC various underground areas are partly equipped with commercial electronic devices not specifically designed to be radiation tolerant. A major concern is therefore radiation induced failures in particular due to Single Event Upsets (SEU). To ensure safe and acceptable operation of the LHC electronics a combination of both FLUKA Monte Carlo simulations and dedicated online monitoring is applied to determine the expected radiation levels in critical areas. The LHC Radiation Monitor (RadMon) which is used for this purpose has already been extensively calibrated for its radiation response in various irradiation facilities. It is nevertheless of high importance to also provide a real LHC application benchmark to validate the approach of combined simulations and montoring to correctly measure and predict radiation levels. This report therefore presents a comparison between FLUKA Monte Carlo simulations and measurements results using the RadMon in the LHC collimation region IR7. The work is carried out within the frame work of the R2E project.
