Fluctuations of the surface membrane potential due to adsorbtion and desorbtion of ions when environmental fluctuations generate a fluctuation in the number of adsorbtion sites were investigated. The correlation functions of surface charge density, surface potential and the spectral density of surface potential fluctuations were calculated. The characteristic features of these fluctuations were determined.

We propose to study the radiation environment on board different flight vehicles: cosmos-type satellites, orbital stations, Space Shuttles and civil (sonic and supersonic) aircraft. These investigations will be carried out with single type of passive detector, namely, nuclear photoemulsions (NPE) with adjustable threshold of particle detection within broad range of linear energy transfer (LET) that is done by means of the technique of selective development of NPE exposed in space. These investigations will allow, one to determine: integral spectra of LET of charged particles of cosmic ray (CR) over a wide range from 2.

A stochastic model of localized adsorption of particles on the membrane was constructed. In the model, the transitional processes were neglected, and adsorption was represented as a stationary Markov process. In the framework of this approach, stationary values of average numbers of particles, there dispersion, correlation function, and spectral density were estimated.
