Results of Detecting Thermal Neutrons at Tien Shan High Altitude Station

The unit for detecting thermal neutrons, which makes it possible to study variations in cosmic rays of the interplanetary and geophysical origin, has been created at the high altitude cosmic ray station (3340 m above sea level) near the Earth's crust fault. It has been established that variations in thermal neutrons are of the same nature as highenergy variations registered wi th a neutron supermonitor in the absence of seismic activity. The flux of thermal neutrons from the Earth's crust during seismic activity in December 2006 has been registered for the first time. The flux value is higher than the background level by 5-6%. The method for detecting the flux of thermal neutrons from the Earth's crust with the simultaneous registration of high� energy neutrons has been proposed.
