We analyze the possibility of using a low-background Ge-NaI spectrometer in a reactor experiment aimed at searches for the neutrino magnetic moment down to 3 × 10-11 of the electron magneton. The properties of the so-far existing low-background Ge spectrometers are discussed, and additional sources of background in a reactor experiment at a small depth are estimated. These estimates place specific requirements on the design of the spectrometer. The results of preliminary background measurements at a small depth of 5 mwe with a dedicated spectrometer built at ITEP are reported.
