Natural radionuclides as background sources in the Modane underground laboratory

Popis výsledku v původním jazyce

The Modane underground laboratory (LSM) is the deepest operating underground laboratory in Europe. It is located under the Frejus peak in Savoie Alps in France, with average overburden of 4800 m w. e. (water equivalent), providing low-background environment for experiments in nuclear and particle physics, astrophysics and environmental physics. It is crucial to understand individual sources of background such as residual cosmic-ray flux of high-energy muons, muon-induced neutrons and contributions from radionuclides present in the environment. The identified dominant sources of background are radioactive contamination of construction materials of detectors and laboratory walls, radon contamination of the laboratory air, and neutrons produced in the laboratory. The largest neutron contribution has been identified from (alpha, n) reactions in low Z materials (10(-)(7)-10(-)(4) n s(-1) Bq(-1)) and from spontaneous fission of U-238 (10(-)(6) n s(-1) Bq(-1)).
