内容記述 |
Cosmic-ray-produced atmospheric neutrons with energies of less than 1MeV were observed on the snow field at Mizuho Station (70.7°S, 44.3°E, 2230m elevation), East Antarctica. Five-month recordings of the two BF_3 proportional counters, which were installed about 70cm above and below the snow surface respectively, show that atmospheric neutron fluxes observed at air-snow boundary are between the two expected fluxes at air-soil and air-water boundaries. The attenuation of neutrons in very deep snow cover is intermediate between that in snow cover on soil, that is, a snow-soil interface, and in water, equivalent to a water-water interface. This work suggests an application to estimation of water equivalent depths of a snow cover accumulated on a permanent snow field, or on a glacier, using atmospheric neutrons. |
