"Compared with other nuclear events: The Chernobyl explosion put 400 times more radioactive material into the Earth's atmosphere than the
The Chernobyl nuclear accident was caused by an unfortunate cocktail of human error and flawed reactor design. It was the worst nuclear disaster in history, releasing more than 400 times as much radioactive material as the Hiroshima atomic bomb.
The Chernobyl accident (1986) was classified at level 7 (maximum) because of its consequences on the environment and the exposures suffered by the populations.
On April 26, 1986, a routine test at the Chernobyl nuclear power plant triggered explosions that killed workers and released more than 100,000 lbs. of radioactive material into the atmosphere - 400 times more radiation than the atomic bomb dropped on Hiroshima.
On April 26, 1986, Chernobyl's reactor number four melted down as a result of human error, releasing vast quantities of radioactive particles and gases into the surrounding landscape – 400 times more radioactivity to the environment than the atomic bomb dropped on Hiroshima.
Compared with other nuclear events: The Chernobyl explosion put 400 times more radioactive material into the Earth's atmosphere than the atomic bomb dropped on Hiroshima; atomic weapons tests con ducted in the 1950s and 1960s all together are esti mated to have put some 100 to 1,000 times more radioactive material into ...
Answer and Explanation: There are two reasons that truly differentiate between Chernobyl and Hiroshima. The first was that the explosion at Chernobyl happened on the ground, whereas the explosion at Hiroshima happened high in the air above the city, which greatly reduced the radioactive levels.

How Long Will It Take For Ground Radiation To Break Down? On average, the response to when Chernobyl and, by extension, Pripyat, will be habitable again is about 20,000 years.
A recent study found evidence that Chernobyl is now less radioactive than the Marshall Islands, where the US conducted 67 nuclear tests after World War II.
The accident at Fukushima occurred after a series of tsunami waves struck the facility and disabled systems needed to cool the nuclear fuel. The accident at Chernobyl stemmed from a flawed reactor design and human error. It released about 10 times the radiation that was released after the Fukushima accident.
To date, there have been two Level 7 accidents: Chernobyl disaster, 26 April 1986.
Level 7 is the most serious level on INES and is used to describe an event comprised of “a major release of radioactive material with widespread health and environmental effects requiring implementation of planned and extended countermeasures”. This is only the second Level 7 accident in the nuclear industry.
The Fukushima accident was an accident in 2011 at the Fukushima Daiichi (“Number One”) nuclear power plant in Japan. It is the second worst nuclear accident in the history of nuclear power generation, behind the Chernobyl disaster.
More than 30 years on, scientists estimate the zone around the former plant will not be habitable for up to 20,000 years. The disaster took place near the city of Chernobyl in the former USSR, which invested heavily in nuclear power after World War II.
How large an area was affected by the radioactive fallout? Some 150,000 square kilometres in Belarus, Russia and Ukraine are contaminated and stretch northward of the plant site as far as 500 kilometres. An area spanning 30 kilometres around the plant is considered the “exclusion zone” and is essentially uninhabited.
Chernobyl animals are mutants ...
Among breeding birds in the region, rare species suffered disproportional effects from the explosion's radiation compared to common species.
Fukushima is the most radioactive place on Earth. A tsunami led to reactors melting at the Fukushima nuclear power plant. Even though it's been nine years, it doesn't mean the disaster is behind us.
If the three courageous men were not successful in their mission the Chernobyl death toll was likely to reach the millions. Nuclear physicist Vassili Nesterenko declared that the blast would have had a force of 3-5 megatons leaving much of Europe uninhabitable for hundreds of thousands of years.
It is thought that the reactor site will not become habitable again for at least 20,000 years, according to a 2016 report.
The answer is a definitive no. After the Hiroshima and Nagasaki bombs, residual radiation was left behind but this declined rapidly. According to the city of Hiroshima local government website, research has indicated that 80 percent of residual radiation was emitted within 24 hours of the bombing.
Called the world's worst-ever civil nuclear incident, it is one of only two nuclear energy accidents rated at seven—the maximum severity—on the International Nuclear Event Scale, the other being the 2011 Fukushima nuclear disaster in Japan.
The explosion was chemical, driven by gases and steam generated by the core runaway, not by nuclear reactions; no commercial nuclear reactor contains a high enough concentration of U-235 or plutonium to cause a nuclear explosion.
The damage caused would be internal, with the injurious effects appearing over many years. For the survivors of a nuclear war, this lingering radiation hazard could represent a grave threat for as long as 1 to 5 years after the attack.
Under the INES, Three Mile Island is classified as Level 5, an accident with wider consequences, whereas both Fukushima and Chernobyl are Level 7, major accidents.
