This included turning off most automatic safety controls and removing ever more control rods which absorb neutrons and limit the reaction. As they ran the experiment, less cooling water entered the reactor, and what was there began to turn to steam. As less coolant was available, the reaction increased to dangerous levels. To counteract this, the operators tried to reinsert the remaining control rods.
Sadly, the rods also had a design flaw, graphite tips remember, graphite encourages the nuclear reaction. When the nearly graphite tips were inserted into the fuel, reactivity increased and the whole thing blew up. It is estimated that about seven to ten tons of nuclear fuel were released and at least 28 people died directly as a result of the explosion. It is further estimated that over 90, square miles of land was seriously contaminated with the worst effects being felt in Ukraine, Belarus and Russia.
However, radiation quickly spread in the wind and affected wide swaths of the northern hemisphere and Europe, including England, Scotland and Wales.
Hard data on the number of people who died as a result of the radioactive release are difficult to find. It is known that of the people exposed to super high radiation levels immediately after the accident, 47 are now deceased.

Schoolchildren in uniforms skipped by in small groups. It could have been a scene from any city. But Hiroshima, of course, is not just any city. About yards north of Motoyasu Bridge stands another bridge, the Aioi. The span was the original target for the bombing crew of the Enola Gay , which dropped a nearly 10,pound uranium bomb that detonated close to the spot where I was perched.
I was in Hiroshima to do research and conduct interviews for my book about World War II reporter John Hersey—the first journalist to reveal the true aftermath of the bomb here, particularly its radioactive impact on human beings. When Hersey arrived in Hiroshima in , eight months after the bombing, he found a post-apocalyptic wasteland.
Now Hiroshima Prefecture is home to nearly three million people and is a major tourist destination. When I met Ms. Kondo, she was alternately solemn and mischievous, with a pronounced gallows humor. She was then 74, but as we walked through the city together, I could hardly keep up with her.
As we walked down a wide, tree-lined boulevard that sunny morning, it was hard for me to comprehend that this was the site of the first nuclear attack in history, and that Ms.
Kondo was one of the few humans on Earth to have witnessed and survived it. For those who lived, memories of the bomb are impossible to forget.
When the U. The true death toll—estimates have ranged between , and ,—will never be known. Koko Tanimoto Kondo was eight months old when the bomb hit less than a mile from her home, causing it to collapse. Her mother managed to dig out of the wreckage, and they both survived.
Like other bomb survivors, the painful experiences of her childhood compel Ms. Kondo to work for peace, including leading a peace study tour throughout Japan, and sharing her story in venues around the world. Not only near the epicenter, but across the city. At the time of the bombing, Ms. The house collapsed on top of them, but her mother managed to free them from the debris and escape before a wall of flame consumed the area.
Had the city been attacked by a massive force of Bs? Had a new sort of weapon been used? How else could such devastation be explained? On August 8, he reported back to the Japanese government. A Japanese report soon estimated that nearly 66, buildings had been razed or damaged. A subsequent U. Stack Overflow for Teams — Collaborate and share knowledge with a private group.

Asked 8 years, 6 months ago. Active 6 years, 6 months ago. Viewed k times. Improve this question. Jim There are populated cities with higher ambient radiation levels. So it's not inhabited only because of intertia, fear and bureaucracy. BTW I lived for 15 years km from Chernobyl. Add a comment. Active Oldest Votes. Improve this answer. Jim Jim I is made in abundance in nuclear reactors, but in nuclear fission contamination events especially Chernobyl , I is created in sufficiently dangerous levels.
It has a halflife of So when I said the iodine isotope is relatively long-lived and dangerous to humans, I was not incorrect. And Cs isn't as long lived as it 30 years vs Wouldn't you need a billion times more of it to be equally dangerous? It is more dangerous than other Iodine isotopes. Specifically, I, I, I, and I It is less dangerous than I and I
