The Fukushima Disaster has Doused Radiation on Everyone on Earth

Ecology and Environment, Fukushima, News, Nuclear Power

In the aftermath of the March 2011 earthquake and tsunami left many regions in Japan destroyed and under water, it has been a well known fact that the most effected area of region has been the Fukushima prefecture, what was once a rural haven has been to transformed into a desolate wasteland due to the destruction and compromise of nuclear reactors. While clean up is still well underway 6 years later, reports that the consequences of the disaster is much more far reaching than we once thought. According to research, everyone on Earth has been effected, having been doused with a dose of radiation.

As Raw Story reports:

Japan’s 2011 Fukushima nuclear disaster had an impact on every single person on Earth, according to scientists. The meltdown hit everyone on the planet with a dose of radiation, but fortunately, not enough to have a real impact.

The disaster dosed everyone on Earth with radiation equivalent to that of a single x-ray, according to the first global survey of the radiation’s effect. In other words, a negligible amount.

“We don’t need to worry,” said Nikolas Evangeliou, according to New Scientist. He is part of the team at the Norwegian Institute for Air Research that conducted the survey.

The average person was dosed with 0.5 millisieverts of radiation from the accident. For those in the immediate vicinity of Fukushima, the amount was much higher, at about one to five millisieverts. It takes about 1000 millisieverts to cause radiation sickness. The World Nuclear Association holds that no deaths or cases of radiation sickness were caused by the accident.

“More than 80 percent of the radiation was deposited in the ocean and poles, so I think the global population got the least exposure,” he said. “What I found was that we got one extra x-ray each.”

For comparison, the average American receives about 6.2 millisieverts per year, according to the United States Nuclear Regulatory Commission. That radiation comes partly from natural background radiation, or sources naturally occurring on earth like radon in the air and cosmic rays. The other half comes from man-made sources like medical procedures and industrial sources.

The team noted that while the effect on humans was minimal, plants and animals were likely impacted much more significantly. Bird populations in areas around Fukushima showed a decline between 2011 and 2014. The team also said the 1986 Chernobyl disaster, the worst nuclear accident in history, had a far worse impact on humans because the fallout was larger and hit areas that were much more populated.

While the amount of radiation received by the overall population was negligible, that’s not to say the disaster didn’t have direct effects on health. There have been ongoing disputes over whether increased cases of thyroid cancer were a direct result of radiation or just a result of overdiagnosis. Thyroid cancer is, however, known to be caused in some cases by radioactive iodine released during nuclear accidents like the one at Fukushima.

“The evidence suggests that the great majority and perhaps all of the cases discovered so far are not due to radiation,” said Dillwyn Williams, a thyroid cancer specialist at the University of Cambridge in the United Kingdom, according to the journal Science.

The prefectural government of Fukushima also denied the cases are linked to radiation. But a support group for children with thyroid cancer contends otherwise. The 3.11 Children’s Fund for Thyroid Cancer discovered after auditing medical bills that a 4-year-old had a thyroid operation at a state-run university despite the university saying it had never treated a person under five for thyroid cancer

While the exposure is declared to be minimal, efforts to decommission the plant clean up indicate that the problem is larger than authorities wish to disclose.

In any case, Fukushima and Japan as a whole are still dealing with the after-effects of the disaster. The company responsible for decommissioning the plant, known as Tepco, said that while they’ve made significant progress, the multibillion-dollar process could likely take decades.

“We have caused it,” Daisuke Hirose, a spokesperson for Tepco, told the Japan Times in April. “We have to make every effort to create a place to which people want to return”

What do you think about the effects of the Fukushima disaster and the discovery that everyone on earth has been exposed? Do you think that over time the effects will be more of a concern as radiation continues to leach out in higher in higher doses? Do you buy the facts being sold to you that there is nothing to worry about? Share you thoughts in the comments below.
