Radioactive Contamination

<<< Environmental Problems Index | Nuclear Facilities in the Russian Federation >>>

From Estonia on the Baltic Sea to Russia's Far East on the Pacific, the former Soviet Union (FSU) created both an economy and a military establishment that involved intensive development of nuclear facilities. An unfortunate consequence of this has been that in dozens of locations both land and water are polluted by radioactive by-products of nuclear energy production and military weaponry. Thousands of people are sick or dead from radioactive causes, millions of hectares are too polluted for normal human activity, and the resources needed to clean up this dangerous situation are staggering and at present unobtainable. Of all the legacies left by the USSR, almost certainly the most costly in the long run will be nuclear contamination.

Overview

In 1945, the United States was the only nation possessing the atomic bomb. To Josef Stalin and his generals, this was unacceptable. To them, the USSR had to be equal, and preferably superior, to its ideological enemy in every way, and most certainly in strategic military capability. This meant acquiring nuclear weapons as quickly as possible, at any cost.

A crash programme was begun, and before the end of the 1940s, the Soviet Union had ended America's monopoly on nuclear weapons. But Stalin did not want just a few nuclear devices, he wanted thousands, and to achieve this, a vast array of mining, processing, manufacturing, and disposal sites had to be developed. And, in Stalin's usual manner, all this had to be done in total secrecy. Across the Soviet Union, secret uranium mines, secret enrichment plants, secret nuclear power plants, secret bomb production facilities, secret waste storage sites, and even entire secret cities were built with impressive speed, but often with far from impressive safety procedures. Eventually, as the saying goes, the piper would have to be paid.

The potential sources of nuclear contamination in any country with both civilian and military atomic energy programmes are numerous. A review of the nuclear fuel cycle might be useful at this point. The nuclear fuel cycle starts with mining uranium ore, generally with nearby concentrator facilities. Next, the ore travels to enrichment plants, where the percentage of fissionable isotopes is increased. It is then processed into either fuel rods for nuclear reactors, or into bomb-grade uranium having chain reaction capability. After nuclear fuel has been used, it must be reprocessed so that it may be safely stored in designated repositories. Reprocessing produces by-products that are highly radioactive and which must be safely isolated from contact with the biosphere, in some cases for thousands of years.

The Soviet Union constructed a large number of nuclear power plant complexes for both civilian and military purposes; when operated properly, background levels of radiation at these stations are not exceeded. At the other extreme, all 'nuclear powers' utilize restricted sites for testing atomic weapons, and the former atmospheric tests produced highly contaminated regions. Over one hundred locations also exist in the former Soviet republics where nuclear bombs were exploded underground for economic reasons, such as stimulating oil and gas production, or creating storage cavities or surface depressions; these were the so-called 'peaceful atom' projects (also experimented with by the United States). Finally, there are those regions grossly contaminated by accidental releases of radiation, sometimes over vast areas, such as from Chernobyl.

Every former Soviet republic had at least one facility or location involved with nuclear development, as shown in Table 19.1 and Figure 19.1. Latvia, Azerbaijan, and Moldova were the least affected, with just one site each, none of which involves significant contamination. However, four republics - Russia, the Ukraine, Belarus, and Kazakhstan - each have at least one region of serious high-level contamination, as well as numerous potential ones. The status of nuclear actives and problems in the Soviet successor states has been widely discussed in recent years (e.g., Potter, 1993; Pryde and Bradley, 1994; Donnay et al, 1995; Bradley, 1997).

Sites with moderate to severe radioactive contamination can be found in over a hundred locations across the FSU, including in its offshore waters. The nature and extent of such contamination in the former Soviet republics has recently been examined in great detail in the most comprehensive work on this subject to appear to date (Bradley, 1997).

The next two sections of this chapter will briefly describe the nuclear installations to be found in each of the fifteen former Soviet republics. Following this, an examination of the most highly contaminated regions of the FSU will be conducted.
