Nuclear Exaggeration Is Atomic Radiation as Dangerous as We Thought?
Part 2: Atomic Dangers or Doomsday Folklore?
A report warning of the dangers was sent to Moscow in 1951. A series of X-ray tests was conducted, and police officers were assigned to guard the river. "We could only see the river through barbed wire or from a small wooden bridge," says a former resident. By 1960, 22 villages had been evacuated.

But as the analyses show, even this accusation is exaggerated. The US National Cancer Institute (NCI) studied 29,873 people who lived along the Techa between 1950 and 1960. According to the NCI scientists, only 46 deaths came about due to radiation exposure.
The German researchers now know why the death rate was relatively low. Although the Techa was abused as a nuclear waste dump, the abuse was not as severe as the rumor-mongers would have us believe. "The Techa farmer most heavily exposed to the radiation received a dose of only 0.45 Gray," explains Jacob. By comparison, a lethal dose of radiation, which causes fever, changes in the composition of the blood, irreparable damage to the body and death within two weeks, is 6 Gray.
The findings hardly jive with the popular image of the atom as evil incarnate. Nightmarish scenarios of lingering illness and birth defects on an apocalyptic scale populate nightmares. In West Germany, the moral and political self-image of an entire generation arose from its battle against radiation, from "no nukes" protest marches to facing off against police water cannons at the Brokdorf nuclear power plant to sit-ins in front of Castor rail containers of reprocessed nuclear waste.
This hard-line stance was partly rooted in history. On Aug. 6, 1945, a US bomber dropped an atomic bomb code-named Little Boy over Hiroshima. The bomb detonated at an altitude of 600 meters (about 2,000 feet), directly above the center of the city and the resulting fireball, generating temperatures in excess of 5,000 degrees Fahrenheit, swept away all of downtown Hiroshima, killing 140,000 people. Three days later, a second atom bomb was dropped over Nagasaki, killing 70,000.
The more recent meltdown at the reactor in Chernobyl in 1986 reminded the world of the dangers of the atom. The incident was referred to as "nuclear genocide," and the press wrote of "forests stained red" and of deformed insects. The public was bombarded with images of Soviet cleanup crews wearing protective suits, bald-headed children with cancer and the members of cement crews who lost their lives in an attempt to seal off the cracked reactor with a concrete plug. Fifteen years after the reactor accident, the German newsmagazine Focus concluded that Chernobyl was responsible for "500,000" deaths.
The Sellafield nuclear plant in England was the site of a devastating fire in 1957.
In fact, contemporaries who reported on the Chernobyl incident should have known better. Even in the 1980s, radiobiologists and radiation physicists considered the media's doomsday reports to be exaggerated.
And their suspicions have become a virtual certainty today. Groups of researchers have set up shop at all of the sites of nuclear accidents or major nuclear contamination. They work at Hanford (where the United States began producing plutonium in 1944), they conduct studies in the English town of Sellafield (where a contaminated cloud escaped from the chimney in 1957), and they study the fates of former East German uranium mineworkers in the states of Saxony and Thuringia. New mortality rates have now been compiled for all of these groups of individuals at risk. Surprisingly, the highest mortality rates were found among the East German mineworkers.
In Hiroshima, on the other hand, radioactivity claimed surprisingly few human lives. Experts now know exactly what happened in the first hours, days and weeks after the devastating atomic explosion. Almost all of Hiroshima's 140,000 victims died quickly. Either they were crushed immediately by the shock wave, or they died within the next few days of acute burns.
But the notorious radiation sickness -- a gradual ailment that leads to certain death for anyone exposed to radiation levels of 6 Gray or higher -- was rare. The reason is that Little Boy simply did not produce enough radioactivity. But what about the long-term consequences? Didn't the radiation work like a time bomb in the body?
To answer these questions, the Japanese and the Americans launched a giant epidemiological study after the war. The study included all residents of Hiroshima and Nagasaki who had survived the atomic explosion within a 10-kilometer (6.2-mile) radius. Investigators questioned the residents to obtain their precise locations when the bomb exploded, and used this information to calculate a personal radiation dose for each resident. Data was collected for 86,572 people.
Today, 60 years later, the study's results are clear. More than 700 people eventually died as a result of radiation received from the atomic attack:
- 87 died of leukemia;
- 440 died of tumors;
- and 250 died of radiation-induced heart attacks.
- In addition, 30 fetuses developed mental disabilities after they were born.
Such statistics have attracted little notice so far. The numbers cited in schoolbooks are much higher. According to Wikipedia, the online encyclopedia, 105,000 people died of the "long-term consequences of radiation."
Miners in an East German uranium mine were heavily exposed to radon.
Especially surprising, though, is that the stories of birth defects in newborns are also pure fantasy. The press has repeatedly embellished photos of a destroyed Hiroshima with those of deformed children, children without eyes or with three arms. In reality, there hasn't been a single study that provides evidence of an elevated rate of birth defects.
A final attempt to establish a connection is currently underway in Japan. The study includes 3,600 people who were unborn fetuses in their mothers' wombs on that horrific day in August 1945. But it too has failed to furnish any evidence of elevated chromosomal abnormality.
In Germany, where nuclear fears have coalesced with the fear of dying forests and mad cow disease into a general psychosis of threat, the degree of concern over nuclear radiation remains high. To this day, some are so fearful about the long-term effects of fallout from Chernobyl that they refuse to eat mushrooms from Bavaria. Even 20 years ago such behavior would not have made sense.
Officially 47 people -- members of the emergency rescue crews -- died in Chernobyl from exposure to lethal doses of radiation. This is serious enough. "But overall the amount of radiation that escaped was simply too low to claim large numbers of victims," explains Kellerer.
The iodine 131 that escaped from the reactor did end up causing severe health problems in Ukraine. It settled on meadows in the form of a fine dust, passing through the food chain, from grass to cows to milk, and eventually accumulating in the thyroid glands of children. About 4,000 children were afflicted with cancer. Less well-known, however, is the fact that only nine of those 4,000 died -- thyroid cancers are often easy to operate on.
"Chernobyl was certainly a catastrophe," says GSF spokesman Heinz-Jörg Haury. "But it was also distorted and exaggerated."
Still, there is no doubt that radiation poisoning remains ominous and highly dangerous. It is also still something of a puzzle to researchers. Stalin's old weapons plant at Mayak is, in that sense, a goldmine for researchers. It is the equivalent of a laboratory containing thousands of well-documented cases.
"Russian doctors have accumulated a huge store of knowledge in Mayak," explains Haury, "which is why everyone wants to go to Siberia now."
Plans are already underway for the next expedition.
