BIG CREATION, SMALL CREATURE:

Is Atomic Radiation as Dangerous as We Thought?: A mounting number of studies are coming to some surprising conclusions about the dangers of nuclear radiation. It might not be as deadly as is widely believed. (Matthias Schulz, 11/22/07, Der Spiegel)

There, in a long brick building, workers, including many women, sat in a dimly lit environment and placed the encrusted rods into nitric acid, triggering a process that allowed them to remove the weapons-grade plutonium. While the same work was performed with remote-controlled robotic arms in the West, the Soviet workers were not even given masks to wear. There was nothing to stop plutonium gases from entering their lungs.

And yet the amount of health damage sustained by these workers was astonishingly low. The GSF study has examined 6,293 men who worked at the chemical plant between 1948 and 1972. "So far 301 have died of lung cancer," says Jacob. "But only 100 cases were caused by radiation. The others were attributed to cigarettes."

The second large, but as yet unpublished study by the GSF scientists also offers surprisingly low mortality figures. The subjects in this study were farmers who lived downstream from the nuclear reactors, in 41 small towns and villages along the Techa River. From 1949 to 1951, waste material from the plutonium production -- a bubbling toxic soup -- was simply poured into the river untreated. As a result, highly radioactive elements such as cesium 137 and strontium 90 were deposited in the river's sediments. The riverbanks became radioactive.

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.

From the standpoint of Russian citizens' groups, which are currently suing for compensation in the courts, these official steps were half-hearted. In their view, the plant management committed "atomic genocide" against the ethnic Tatars living in the area.

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.

Was all this just doomsday folklore? There is no doubt that large sections of the countryside were contaminated by the accident in the Ukraine. In the ensuing decades, up to 4,000 cleanup workers and residents of the more highly contaminated areas died of the long-term consequences of radiation exposure. But the six-figure death counts that opponents of nuclear power once cited are simply nonsense. In most cases, they were derived from vague "extrapolations" based on the hearsay reported by Russian dissidents. But such horror stories have remained part of the nuclear narrative to this day.

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."

"For commendable reasons, many critics have greatly exaggerated the health risks of radioactivity," says Albrecht Kellerer, a Munich radiation biologist. "But contrary to widespread opinion, the number of victims is by no means in the tens of thousands."

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.

It's worth noting that the folks who succumb to hysterias about the supposed threat humans represent to the planet are those who have a warped view of the Chain of Being.
