Mobile communications provides a new source of electromagnetic exposure for almost the whole population of Russia. For the first time in the history of civilization, the brain of mobile phone users is exposed to localized radiofrequency (RF) electromagnetic fields (EMF). Base stations are a factor in the exposure of the population. Existing standards for limiting exposure do not account for the role of base stations as a source of EMF and cannot guarantee the absence of adverse health effects. It has become necessary to obtain reliable information to expand databases for the development of new standards. As recommended by the World Health Organization, an additional experiment is performed under the supervision of foreign experts, which shows changes in autoimmune status in rats after long-term low-level RF EMF exposure with an incident power of 500 μW/cm2. © 2010 Pleiades Publishing, Ltd.

The ecotoxicological properties of sediments from reservoir R-11 of the Techa River cascade are studied in comparison to the Shershni reservoir. Radiochemical analysis of sediment and water samples from R-11 show that the radioactivity of the sediments ranges from 240 to 360 kBq/dm3 dry weight for 90Sr and from 10 to 161 kBq/dm3 dry weight for 137Cs. The absorbed doses for Oligochaeta from R-11 are calculated on the basis of radiochemical data. The hydrobiological studies include (1) study of the population density and diversity of Oligochaeta species in the reservoirs and (2) laboratory bioassay of sediments with Tubifex tubifex as a biomonitor species. The results indicate that the Oligochaeta population density in R-11 is less than in the Shershni reservoir. No significant effects of the absorbed dose rate on population density, survival rate, or fertility are found in a laboratory Tubificidae bioassay of R-11 sediments. However, a decrease in fertility is noted in experiments at a higher absorbed dose. © 2010 Pleiades Publishing, Ltd.
