The changes of parameters of space plasma as a signal about a pollution of the environment

The outcomes of simultaneous "Intercosmos" satellite measurements of magnetic and electrical component a of low frequency emissions field, low-energy electrons and density and temperature of ionospheric plasma are analyzed. The results of supervision are discussed in comparison with ionospheric anomalies simultaneously observed on board of Japan satellite ISS-b. It is established, that in Barents and Kara seas area observation results of simultaneous small-scale changes (fluctuations) of plasma parameters have coincided with zones of the increased contents of cesium (¹³⁷Cs) in bottom sediments. We proposed a method of detection of radiological contaminations (pollutions) based on results of complex analysis of satellite measurements of intensity a magnetic and electrical component of a low frequency emission field, and plasma parameters at satellite orbit heights.
