Abstract: | Thermal neutron fluxes were measured using two types of scintillation detectors based on the inorganic scintillator ZnS(Ag):
6LiF+ZnS(Ag) and 10B2O3 + KCl+ZnS(Ag). The preliminary results from these measurements are given. The thermal neutron concentration as a function
of altitude above sea level was determined. The measurements were performed at three locations: in Moscow, at the Baksan Neutrino
Observatory of the Russian Academy of Sciences, and at the Gran Sasso National Laboratory. Variations of neutron count rates
associated with lunar cycles were observed at the remote laboratories. |
