Volginsky Field is located on lands of the scientific testing base for experimental animals of the All-Russian Scientific Research Institute of Agricultural Radiology and Agroecology, not far from the settlement of Volginsky, Petushki Region, Vladimir Oblast.
From 1972 through 1982, the institute added cesium-137, strontium-90, thorium-232, and uranium-238 radionuclides to the soil of an experimental plot. In addition, the field also featured three buried vessels 1.5 m in diameter that were partially filled with radioactive waste. There were also two piles of soil measuring 10 m3 each that were contaminated with cesium-137 and strontium-90. The maximum depth to which the radionuclides had penetrated was 0.5 m.
A detailed radiation study conducted by the Joint Environmental-Technological Scientific Research Center for Radioactive Waste Decontamination and Environmental Protection (Radon) in the summer of 2003 indicated the following:
The area affected by radioactive contamination hot spots (experimental plots, vessels for solid and liquid radioactive waste, and adjacent plots and soil piles) totaled 2,200 m2.
The maximum depth of the contaminated soil layer was 0.3 to 0.4 m.
The gamma-irradiation exposure dose intensity at the contaminated sites ranged from 15 to 2,100 mR per hour at a distance of 0.1 m from the soil surface and from 60 to 1,250 mR per hour at 1 m from the surface.
The volume of radioactive wastes in the form of contaminated soil totaled 670 to 1,500 m3.
The average volume of radioactive waste in the form of construction debris (concrete vessels for the storage of solid radioactive waste) and metal items (liquid radioactive waste storage vessel) was 10 to 20 m3.
In early 2007, more than 450 m3 of radioactive waste was removed from this site. Work to decontaminate the site is ongoing.
The radioactive contamination site near Solnechnoye Lake was discovered in June 1985. It is located 50 m south of the lake near the city of Ramenskoye in Moscow Oblast and occupies an area of about 1.2 ha (150 × 80 m). The primary radionuclide contaminant is radium-226. Responsibility for the radioactive contamination has not yet been established.
