The paper includes data of experimental investigations of drinking water decontamination in the plasm-chemical reactor; optimal conditions of the process are determined; distinctive features of activation processes occurring as a result of contact action of low-temperature non-equilibrium plasma are shown. The most efficient fields of application of the above technology in conditions of emergency situations and terrorist threats are discussed.

Spectral broadening of signals from a ground-based VLF transmitter was observed onboard the Magion-3 sub-satellite during electron beam injection from the lntercosmos-25 (APEX) satellite. Broadening of the order of 300–500 Hz was apparently correlated with the 2 s-periodic sequence of the electron gun pulses which were modulated in amplitude with frequencies 30.5 < fm < 31,250 Hz. No effects were found for those electron gun pulses with fm = 62.5, 125 and 250 kHz.
