摘要：

Measurements of the background neutron environment, at a depth of 1780 m (4800 mwe) in the Underground Laboratory of Modane (L.S.M.) are reported. Using a Li-6 liquid scintillator, the energy spectrum of the fast neutron flux has been determined. Monte Carlo calculations of the (alpha,n) and spontaneous fission processes in the surrounding rock has been performed and compared to the experimental result. In addition, using two He-3 neutron counters, the thermal neutron flux has been measured. (C) 1998 Elsevier Science B.V.
