Chernobyl: A 20 Year Catastrophe; A Lesson for the Future

April 26, 2006

On April 26, 1986, the Number 4 reactor at the Chernobyl nuclear power plant in Ukraine exploded. The worst accident in the history of the nuclear power industry resulted in the evacuation of hundreds of thousands of people from the contaminated regions around the plant. A plume of radioactivity settled over large areas of Russia, eastern Europe, western Europe, and even reached the United States. A 30-mile "exclusion zone" has been maintained around the reactor site for the past 20 years.

Some 700,000 "liquidators" were drafted to contain the fires, to cap the reactor core, and to decontaminate the plant and the surrounding areas. According to the International Atomic Energy Agency (IAEA), 28 of the "early liquidators" died from acute radiation sickness within three months, another 106 were treated and survived, and 19 died over the next eight years, not necessarily from radiation. An IAEA-sponsored Chernobyl Forum report, issued in September 2005, projected 4,000 total deaths would ultimately be related to the catastrophe.

Since no accurate records were kept, determining the health consequences for the majority of the liquidators and for others exposed to radiation from the event has been extremely difficult. A number of independent reviews, however, have challenged the IAEA's contention that there is "no direct correlation between radiation exposure at Chernobyl and increased cancer or death rates."

In April 2006, IPPNW-Germany estimated there are more than 100,000 Chernobyl-related cases of thyroid cancer, and projected 50,000 additional cases in the future. Genetic damage and congenital deformations may number in the tens or even hundreds of thousands worldwide. More than 90% of the liquidators are invalids, according to statistics from Russian authorities, with higher than average incidences of a variety of illnesses.

The long term health consequences of Chernobyl will be with us for generations to come. The resources provided on this website, including the Chernobyl Forum report and the independent studies challenging the IAEA's findings, are essential information for anyone concerned with the past, the present, and the future of nuclear power.

IPPNW has come to the conclusion that the only responsible course of action is a global phaseout of nuclear energy, not only because of the unacceptable consequences of another Chernobyl, but also because nuclear power and nuclear weapons proliferation are inextricably linked. Only a global investment in safe, clean, renewable energy sources can provide the world's energy needs without risking another Hiroshima or Nagasaki, let alone another Chernobyl.
