Background components of a Ge(Li) spectrometer operated below 15 m w.e. have been studied. The cosmic-ray-induced component, including inelastic neutron scattering, is dominating. Most neutrons are produced within the shield itself by μ --caputure and fast muon interaction. The activation products of these reactions can only be avoided by going deeper underground. This would also suppress the neutron-induced component more effectively than any anticoincidence device or neutron shield.
