On the 25th anniversary of the Chernobyl nuclear power plant disaster in northern Ukraine, a former liquidator offers sobering warnings about radiation exposure, with particular cautions for women near the Japanese nuclear plant catastrophe.
Figures of the number of people harmed by the accident remain in dispute. The International Atomic Energy Agency estimates 4,000 cancer deaths among the individuals most-highly exposed to radiation at Chernobyl and another 5,000 in peripheral populations. But several separate studies predict much higher numbers. One of them, a 2006 Greenpeace report based on national health statistics from neighboring Belarus, estimates 93,000 fatal cancer cases in Belarus, Ukraine and Russia.
Twenty-eight firefighters and clean-up workers died within three months of the disaster, almost all from acute radiation sickness, according to the International Atomic Energy Agency.
But the agency says health studies conducted among samples of the 700,000 registered clean-up workers do not show a direct correlation between radiation exposure and an increase in cancer or disease.
Manzurova disagrees. She attributes several other health conditions to her exposure.
"My health problems started a while ago, and they were medically linked to radiation exposure," she said. "I survived [a stroke] and clinical death and a long period of rehabilitation after."
The International Atomic Energy Agency says that such health problems are more the result of psychological trauma experienced by the liquidators while working in the contamination zone. But Robert Alvarez, a nuclear expert at the Institute for Policy Studies, challenges this notion. He says the powerful effects of radiation on the human body are only just beginning to be understood.
"There's now growing evidence that radiation can cause a lot of other things to happen because it's one of the few environmental poisons that can damage your overall immune system," Alvarez said. "Anything that would do that can cause your overall death rate to increase."
Alvarez said supporters of the nuclear power industry are underestimating the potential risk.
"There is this mindset in the government, amongst public health researchers involved in ascertaining the effects of radiation from nuclear activities, that there's nothing good to occur if we make certain information public," he said.
Alvarez and Manzurova fear that Japan may now be facing a similar situation following the 9.0 earthquake and resulting tsunami that devastated the island nation's northeastern shore on March 11. The natural disasters pummeled the Fukushima Daiichi nuclear facility, where reactor cooling systems failed. Populations within a roughly 12-mile area surrounding the plant have been evacuated following several hydrogen explosions in the reactors and evidence of radiation leakage. Recently Japan raised the severity of the crisis to level 7, the same as the Chernobyl disaster.
While the disasters appear to be comparable in the amount of radiation released, how and where it has been released and the structural damage to the facilities differ greatly.
"With Fukushima . . . reactor vessels which hold these radioactive cores have more or less remained intact," Alvarez said. "There may be cracks or other things which may compromise their integrity, but they don't have that kind of full-blown release of everything that Chernobyl experienced."
But he added that Chernobyl was one reactor, while Fukushima is four reactors plus spent fuel pools. "And the spent fuel pools do not have that extra barrier of steel and concrete to prevent the escape [of radiation]."
Alvarez says if the Fukushima crisis continues to escalate, it will put many Japanese at risk, particularly women and children.
"Women are twice as sensitive to contracting cancer of the thyroid and breast [from ionizing radiation] than men, and of course, you have the offspring," Alvarez said. "Exposures during that period [pregnancy] are much more serious than they would be for an adult, and you're looking at the probability for raising the risk of childhood cancer and things like that."
Manzurova hopes the Fukushima nuclear catastrophe will inspire public demand for energy alternatives. She believes that similar accidents will continue to occur unless the industry is held accountable and takes safety precautions much more seriously. Her advice to the people of Japan is to monitor the situation themselves and to demand accurate information from their leaders.
"The matter of rescuing is in the hands of the person being rescued. As soon as [the people] recognize the high number of victims in the population and the damage to the environment, then the real cost of the nuclear power industry will be immediately understood for what it is," she said.
