  A large volume scintillation detector is supposed to install at Baksan
neutrino observatory INR RAS at Caucasus. The detector will register all
possible neutrino fluxes, but mainly geo-neutrinos. In the article the neutrino
fluxes are discussed and expected effects in proposed detector are estimated.
The design and construction of such a detector is expected to be a part of all
the world similar detectors net that is under construction in modern times.
