AbstractThe changes in the geological environment during construction of nuclear stations are considered.
Special attention has been given to the changes typical of nuclear power facilities: radioactive pollution and
appearance of the ionizing emission fields, which cause decomposition of rock-forming minerals and radiolysis
of groundwater. The combined action of many anthropogenic factors weakens a soil massif and induces heat,
radiation, and chemical anomalies. On terminating radioactive contamination, the geological environment grad-
ually eliminates technological radiation.
