  Cosmic muon induced neutrons are a major source of background for low
countrate experiments like neutrino oscillation or dark matter searches.
Especially at shallow sites these neutrons are the limiting factor for the
ultimate sensitivity of the measurement. Measurements of the neutron rate and
counter measures including active veto and passive shielding of the detector
are discussed for two neutrino oscillation experiments at shallow sites: the
KARMEN accelerator based experiment at RAL and the PALO VERDE reactor
experiment.
