For more than three decades, the Soviet Union and now Russia secretly
pumped billions of gallons of atomic waste directly into the earth and,
according to Russian scientists, the practice continues today.
The scientists said that Moscow had injected about half of all the
nuclear waste it ever produced into the ground at three widely dispersed
sites, all thoroughly wet and all near major rivers. The three sites are
at Dimitrovgrad near the Volga River, Tomsk near the Ob River, and
Krasnoyarsk on the Yenisei River. The Volga flows into the Caspian Sea
and the Ob and Yenisei flow into the Arctic Ocean.
The injections violate the accepted rules of nuclear waste disposal,
which require it to be isolated in impermeable containers for thousands
of years. The Russian scientists claim the practice is safe because the
wastes have been injected under layers of shale and clay, which in
theory cut them off from the Earth's surface.
But the wastes at one site already have leaked beyond the expected
range and "spread a great distance," the Russians said. They did not say
whether the distance was meters or kilometers or whether the poisons had
reached the surface.
They began injecting the waste as a way to avoid the kind of
surface-storage disasters that began to plague them in the 1950s. But by
any measure, the injections were one of the Cold War's darkest secrets.
The amount of radioactivity injected by the Russians is up to three
billion curies. By comparison, the accident at the Chernobyl nuclear
power plant released about 50 million curies of radiation, mostly in
short-lived isotopes that decayed in a few months. The accident at Three
Mile Island discharged about 50 curies. The injected wastes include
cesium-137, with a half life of 30 years, and strontium-90, with a half
life of 28 years and a bad reputation because it binds readily with
human bones.
The Russians are now working with the U.S. Department of Energy to try
to better predict how far and fast the radioactive waste is likely to
spread through aquifers.
At best, the Russian waste may stay underground long enough to be
rendered largely harmless by the process of radioactive decay.
At worst, it might leak to the surface and produce regional calamities
in Russia and areas downstream along the rivers. If the radioactivity
spreads through the world's oceans, experts say, it might prompt a
global rise in birth defects and cancer deaths.
At the least, the media should be reporting what progress is being made
by the Department of Energy to monitor this potentially horrendous
disaster.
