The flux density of neutrons with energies of 20-80 MeV produced by muons underground at a depth of 550 meters water equivalent has been measured. The flux density of hadrons with energies above 0.7 GeV is estimated for various depths. The hadron background is important in experiments on the decay of the proton at depths down to 8000 meters water equivalent.
