Chernobyl’s Deadly Effects Estimates Vary
Chernobyl’s Deadly Effects Estimates Vary
April 26 marks the 33rd anniversary of the 1986 radiation disaster at Chernobyl reactor Number 4 in Ukraine, just north of Kiev the capital. It is still nearly impossible to get scientific consensus on the vast extent of the impacts. The explosions and two-week long fire at Chernobyl spewed around the world something between one billion and nine billion curies of radiation — depending on whose estimates you choose to believe. The accident is classified by the UN as the worst environmental catastrophe in human history.
Chernobyl’s radioactive fallout has been blamed for hundreds of thousands of deaths, but the International Atomic Energy Agency (IAEA) acknowledges only 56 deaths among firefighters who suffered and died agonizing deaths in the disaster’s immediate aftermath. However, the IAEA’s officially chartered mission is “to accelerate and enlarge the contributions of nuclear power worldwide.” Because of its institutional bias, one can dispute nearly everything the IAEA says about radiation risk.
Also on the low-end of fatality estimates is the World Health Organization which has to have its radiation studies approved by the IAEA! In 2006, the WHO’s “Expert Group concluded that there may be up to 4,000 additional cancer deaths among the three highest exposed groups over their lifetime (240,000 liquidators; 116,000 evacuees, and the 270,000 residents of the Strictly Controlled Zones).” The WHO added to this 4,000 the estimate that “among the five million residents of areas with high levels of radioactive cesium deposition” in Belarus, the Russian Federation and Ukraine” predictions suggest “up to 5,000 additional cancer deaths may occur in this population from radiation exposure…”
Alternately, Ukraine’s Minister of Health Andrei Serkyuk estimated in 1995 that 125,000 people had already died from the direct effects of Chernobyl’s radiation. Serkyuk said a disproportionate share of casualties were among children, pregnant women and rescue workers or “liquidators.”

Five Years After Fukushima, ‘No End in Sight’ to Ecological Fallout
The environmental impacts of the 2011 Fukushima Daiichi nuclear disaster are already becoming apparent, according to a new analysis from Greenpeace Japan, and for humans and other living things in the region, there is “no end in sight” to the ecological fallout.
The report warns that these impacts—which include mutations in trees, DNA-damaged worms, and radiation-contaminated mountain watersheds—will last “decades to centuries.” The conclusion is culled from a large body of independent scientific research on impacted areas in the Fukushima region, as well as investigations by Greenpeace radiation specialists over the past five years.
“The government’s massive decontamination program will have almost no impact on reducing the ecological threat from the enormous amount of radiation from the Fukushima nuclear disaster,” said Kendra Ulrich, senior nuclear campaigner at Greenpeace Japan. “Already, over 9 million cubic meters of nuclear waste are scattered over at least 113,000 locations across Fukushima prefecture.”
According to Radiation Reloaded: Ecological Impacts of the Fukushima Daiichi Nuclear Accident 5 Years Later, studies have shown:
- High radiation concentrations in new leaves, and at least in the case of cedar, in pollen;
- apparent increases in growth mutations of fir trees with rising radiation levels;
- heritable mutations in pale blue grass butterfly populations and DNA-damaged worms in highly contaminated areas, as well as apparent reduced fertility in barn swallows;
- decreases in the abundance of 57 bird species with higher radiation levels over a four year study; and
- high levels of caesium contamination in commercially important freshwater fish; and radiological contamination of one of the most important ecosystems – coastal estuaries.
The report comes amid a push by the government of Japanese Prime Minister Shinzō Abe to resettle contaminated areas and also restart nuclear reactors in Japan that were shut down in the aftermath of the crisis.
