Observed changes of atomic hydrogen radiation line intensity in the spectrum for plasma formations arising at a collapse of cavity
bubbles in the water of high degree cleaning have been described. The constructive scheme of a cell for cavity creation with
subsequent ecologically safe method of hydrogen concoction from a gas mix has been offered. The influence of cavity creation
device material and chemicals impurity on the spectrum for hydrogen’s luminescence brightness and its formation speed has been
experimentally established. The results of experiments confirm the possibility of hydrogen safe generation in cavity streams and
make actual the need for further researches.
