A Neutron Probe for the Determination of Snow Density and Its Use in Antarctica

A neutron probe for the determination of snow density was designed and built for operation under field conditions. The probe contains a neutron source which emits fast neutrons. The neutrons lose their energy in the snow primarily because of collisions with the hydrogen nuclei. After several collisi...
