The Chernobyl explosion in 1986 was the only nuclear disaster to be rated a Level 7 until now

The nuclear crisis in Japan has had a roller coaster of reports since the 9.0-magnitude earthquake struck on March 11. For instance, CNN and MSNBC.com were caught embellishing their stories early on, trying to make the nuclear danger seem worse than it was. Now, new reports are saying that Japanese officials may be downplaying the amount of radiation released, since the Japanese nuclear regulatory agency has now put the Fukushima Daiichi disaster on the same level as the 1986 Chernobyl explosion.  

The Chernobyl disaster occurred in 1986 when an explosion led to fire that released large amounts of radioactive particles into the atmosphere. This event was the only nuclear disaster in history to be rated a 7 on the International Nuclear Event Scale, but now, the Japanese nuclear regulatory agency has changed Japan's nuclear crisis from a 5 to a 7 on the scale as well.

"This is an admission by the Japanese government that the amount of radiation released into the environment has reached a new order of magnitude," said Tetsuo Iguchi, a professor in the department of quantum engineering at Nagoya University. "The fact that we have now confirmed the world's second-ever Level 7 accident will have huge consequences for the global nuclear industry. It shows that current safety standards are woefully inadequate."

As of now, Hidehiko Nishiyama, deputy director general of Japan's nuclear regulator, says the total amount of radioactive materials released from the plant equals 10 percent of what was released in Chernobyl. Japan's Nuclear Safety Commission noted that 370,000 to 630,000 terabecquerels of radioactive material has been released from Nos. 1 to 3 reactors.  

According to the International Nuclear Event Scale, a Level 7 is described as having "widespread health and environmental effects." The announcement that Japan is now a Level 7 came as Japan was pushing more citizens to evacuate areas near the Fukushima Daiichi plant because of long-term radiation exposure fears. People living within a 12-mile radius of the plant were already ordered to evacuate early on, but now, government officials have ordered those living within a 19-mile radius to stay inside or evacuate the area. 

In addition, communities beyond the 19-mile radius have been evacuated as well due to how the radiation is spreading. Different variables like wind can determine where the radiation spreads. For instance, a community called Iitate, which is "well beyond the 19-mile radius," has had high radiation readings because of wind from the plant. The government is also looking to evacuate Katsurao, Kawamata, Minamisoma and Namie within one month because of concerns regarding long-term radiation exposure. If the conditions grow worse, Naraha, Hirono, Tamura, Kawauchi and other sections of Minamisoma will be evacuated as well. 

"This measure is not an order for you to evacuate or take actions immediately," said Yukio Edano, chief cabinet secretary. "We arrived at this decision by taking into account the risks of remaining in the area in the long term." 

With both the Chernobyl explosion and Japan's nuclear crisis on the same level on the International Nuclear Event Scale, some are worried that Fukushima may become worse than Chernobyl. For instance, Junichi Matsumoto, a nuclear executive for Tokyo Electric Power Company, said his biggest concern is that radiation levels could exceed Chernobyl at some point. But there are some clear distinctions between the two events that make his claim extremely unlikely. The most important difference between Chernobyl and the Fukushima Daiichi nuclear crisis is that most of the radioactive elements in Fukushima's reactors were contained within the reactors. 

"If everything inside the reactor came out, obviously that would surpass Chernobyl," said Seiji Shiroya, a commissioner and the former director of the Research Reactor Institute at Kyoto University. "There was only one troubled reactor there, while we have three or more, so simply speaking, that's three times as worse. But at Fukushima, most of the reactors' radioactive elements remained within the reactor. That's a big difference."

The health effects from Chernobyl are expected to remain worse than Japan's health effects as well. Thirty-one people died in Chernobyl while 20 workers were injured at Fukushima. In addition, Dr. Robert Peter Gale, who led the international medical team responding to Chernobyl, said that if the nuclear crisis in Japan did not become any worse, there would be few, if any, thyroid cancer cases and 200 to 1,500 other cancer cases combined over the next 50 years. In Chernobyl, there were 6,000 excess cases of thyroid cancer alone.  

In regards to whether the Japanese government was downplaying the amount of radiation released, reports indicate that the Japanese government did not have an exact idea of the amounts of radiation released in the early weeks of the event, and "last week had the amounts down to an error margin within several digits."  

"Some foreigners fled the country even when there appeared to be little risk," said Shiroya. "If we immediately decided to label the situation as Level 7, we could have triggered a panicked reaction."

Prime Minister Naoto Kan said Tuesday evening that Japan will rebuild, and that reactors were being stabilized despite this new decision to place the nuclear disaster at a Level 7. He also noted that radioactive material release is declining. In addition, he ordered Tokyo Electric to present new plans for the Fukushima Daiichi plant. 

"What I can say for the information I obtained - of course the government is very large, so I don't have all the information - is that no information was ever suppressed or hidden after the accident," said Kan. 

According to the International Atomic Energy Agency, it measured radiation this past Saturday of 0.4 to 3.7 microsieverts per hour in areas located 20 to 40 miles from the Fukushima Daiichi nuclear plant.

Indirect, direct, sideways, backwards.. The current estimate including thyroid cancer etc (i.e those impacted but not neccesarily deaths) is still lower than the amount of people that DIE mining coal each year.

This does not even include the impact of the actual coal powered plants have on the surrounding environment and the population surrounding them. (including small amounts of radiation being released via fly ash all around the country). We have only scratched the surface in the exploration of the health and environmental risks surrounding these kind of power sources.

And please keep in mind this disaster is the product of two major disaster happening at the same time.

Nuclear power needs to be part of our future power generation. Water, Wind, Solar are not complete alternatives, they just don't have the reliability to be more than 20-30% of our power infrastructure. So its either you stick with coal and natural gas plants for the majority of your power needs, or we move to the cleaner and more efficient source of power in Nuclear.

Those are your choices for the foreseeable future, anyone telling you otherwise needs to wake up inform themselves.

I'm not saying these alternatives can't be used, I'm saying they need to be used in conjunction with other sources.

And on top of that to an old and poorly managed facility. Onagawa isn't having any problems, and that nuclear power plant was closer to the earthquake. What we are seeing here I think is the worst possible thing that could happen to any power plant, and that's only speaking of the dated facilities. If Fukushima had been a modern power plant with current safety designs, this incident would have never occurred despite the tremendous stresses the facility would have seen.
