We present a comparison of some characteristics of helium counters for measurements of low intensity neutron flux.We focus on neutron flux density measurements in low background laboratories.Because of an extremely low counting rate (few events per hour or less), we have concentrated on counter parameters which are sometimes meaningless under regular conditions, i.e. background from internal alpha radioactivity, percentage of events in full energy peak, and the width of this peak.The background depends ...

We register events with large number of neutrons at the ground level as well as in the underground laboratory.These neutrons are produced in secondary cosmic ray interactions with matter surrounding the neutron detectors.We used the set of helium-3 filled gas proportional counters and plastic scintillators.We performed a series of measurements in different experimental setups to determine a role of particle cascades in generation of large neutron multiplicities.With GEANT4 simulation of experimental ...
