Description
Thermodynamic modeling of monitoring studies on well 4-G, which was located on the industrial site of the Chernobyl nuclear power plant, was performed. In the range of pH 9. 5 - 12. 5, an increase in the concentration of strontium in the form of SrOH+ and a decrease in the form of Sr2+ was noted in the groundwater, against the background of an increase in the volumetric activity of 90Sr by 200-500 times to 550 Bq/l. The reason for this was an increase in the ionic strength of solutions >5 mmol/l.
