According to this article, the amount of radioactivity from the Chernobyl accident currently in the environment is "much less than that discharged into the environment at Russian production reactor and spent-fuel reprocessing sites." Three such sites are targeted in this article, the three first built and most contaminated: Mayak, Tomsk-7, and Krasnoyarsk-26. How much the contamination at these cites dwarfs the consequences of Chernobyl is graphically shown in Figure 4. Here the 2.8 million curies f rom "other waste" (from Chernobyl, discharges to oceans and seas, uranium mining and milling, and power reactors) is seen to exceed the combined current radioactivity of the three most contaminated US sites: Oak Ridge, Savannah River, and Hanford.
