Reasons for the difference between the fluxes of electrons and thermal neutrons in secondary cosmic rays on expanses of glaciers (water) and land, located at the same altitude

The investigations performed during several years in the Western Pamir at an altitude of 4000 m above sea level (glacier glade Fortambek and glade Fortambek) have revealed a difference of 20–30% between the fluxes of electrons with energies below 1 MeV and thermal neutrons on the glacier and glade (smaller for the glacier), which is most likely due to the different albedos of thermal neutrons in secondary cosmic rays for the interfaces between two media: air/glacier (water) and air/soil, and, therefore, to the different contributions of electrons from neutron β decay.
