The new method for correcting the charge signal from the large proportional counter is proposed. The correction method makes it possible to consider the loss of primary ionisation electrons in the presence of weakly increasing microimpurities of electronegative gases during long-term measurements. It allows increasing the efficiency of the selection of useful events and thereby increasing the sensitivity to 2υ2K-decay in 124Xe at the level of 2•1022 y from over six years of measurements using a large proportional counter. The classification of various coordinate systems that eliminate singularities at the event horizon of a black hole is generalised. For the first time. A complete description of two types of high-energy processes with the prediction of new phenomena in the vicinity of the black hole horizon is given. Methods for optimising targets for increasing the efficiency of photonuclear production of the radioisotope Mo-99, which is mostly the creation of a domestic photonuclear production of the most demanded radionuclides.
