According to the program “Starfish” of 9 July 1962 of the USA exploded in space above Pacific Ocean H-bomb. With conducting of tests it was discovered, that the explosion is accompanied by the electric pulse of very large amplitude and short duration. In spite of that which from the moment of explosion past is already more than fifty years, the up to now existing electrodynamics to explain this phenomenon does not can. Accompany nuclear explosions such phenomena as the emission of electromagnetic waves in the radio-frequency band, and also the so-called rope tricks. For explaining the phenomena indicated is used the concept of scalar - vector potential, which indicates the dependence of the scalar potential of charge on the speed. This concept was for the first time proposed and developed by the author of monograph. The long-wave radiation by which are accompanied the nuclear explosions, can be the consequence of the transverse plasma resonance in the confined plasma, which is examined in the number of the work of the author.
