ИСТИНА

As part of current and prospective geophysical work in the adit of the Baksan Neutrino Observatory, a complex survey was made of the far unused part of the adit (around ~4300 m from the portal), in which there is practically no effect of forced ventilation. A distinctive feature of this part of the adit is the abundance of sources of fluids of various intensities - from drops to jets beating from the walls. Many springs are characterized not only by the outflow of water, but also by the outflow of a large volume of gases, which manifests itself both in the form of the release of bubbles in the accumulations of water in the lower part of the adit, and in the form of a characteristic hiss of the sources located in the walls. Also, using a dosimeter-radiometer, measurements of the radiation background were carried out in places of increased accumulation of water and gases in the area of the most intense sources.
