Nagaskai’s experience of nuclear bombing – theme for this week

Entering the nuclear age, body by body — the Nagasaki experience, Asia Times, BY  on AUGUST 6, 2015   (From TomDispatch.com)

By Susan Southard  [This essay has been adapted from chapters 1 and 2 of Susan Southard’s new book Nagasaki Life After Nuclear Warbook, Nagasaki: Life After Nuclear War, with the kind permission of Viking.] “…….The five-ton plutonium bomb plunged toward the city at 614 miles per hour. Forty-seven seconds later, a powerful implosion forced its plutonium core to compress from the size of a grapefruit to the size of a tennis ball, generating a nearly instantaneous chain reaction of nuclear fission. With colossal force and energy, the bomb detonated a third of a mile above the Urakami Valley and its 30,000 residents and workers, a mile and a half north of the intended target. At 11:02 a.m., a superbrilliant flash lit up the sky — visible from as far away as Omura Naval Hospital more than 10 miles over the mountains — followed by a thunderous explosion equal to the power of 21,000 tons of TNT. The entire city convulsed.

At its burst point, the center of the explosion reached temperatures higher than at the center of the sun, and the velocity of its shock wave exceeded the speed of sound. A tenth of a millisecond later, all of the materials that had made up the bomb converted into an ionized gas, and electromagnetic waves were released into the air. The thermal heat of the bomb ignited a fireball with an internal temperature of over 540,000 degrees Fahrenheit. Within one second, the blazing fireball expanded from 52 feet to its maximum size of 750 feet in diameter. Within three seconds, the ground below reached an estimated 5,400 to 7,200 degrees Fahrenheit. Directly beneath the bomb, infrared heat rays instantly carbonized human and animal flesh and vaporized internal organs.

As the atomic cloud billowed two miles overhead and eclipsed the sun, the bomb’s vertical blast pressure crushed much of the Urakami Valley. Horizontal blast winds tore through the region at two and a half times the speed of a category five hurricane, pulverizing buildings, trees, plants, animals, and thousands of men, women, and children. In every direction, people were blown out of their shelters, houses, factories, schools, and hospital beds; catapulted against walls; or flattened beneath collapsed buildings.

Those working in the fields, riding streetcars, and standing in line at city ration stations were blown off their feet or hit by plummeting debris and pressed to the scalding earth. An iron bridge moved 28 inches downstream. As their buildings began to implode, patients and staff jumped out of the windows of Nagasaki Medical College Hospital, and mobilized high school girls leaped from the third story of Shiroyama Elementary School, a half mile from the blast.

Nagasaki victimThe blazing heat melted iron and other metals, scorched bricks and concrete Nagasaki-drawing-1buildings, ignited clothing, disintegrated vegetation, and caused severe and fatal flash burns on people’s exposed faces and bodies. A mile from the detonation, the blast force caused nine-inch brick walls to crack, and glass fragments bulleted into people’s arms, legs, backs, and faces, often puncturing their muscles and organs. Two miles away, thousands of people suffering flesh burns from the extreme heat lay trapped beneath partially demolished buildings.

At distances up to five miles, wood and glass splinters pierced through people’s clothing and ripped into their flesh. Windows shattered as far as eleven miles away. Larger doses of radiation than any human had ever received penetrated deeply into the bodies of people and animals. The ascending fireball suctioned massive amounts of thick dust and debris into its churning stem. A deafening roar erupted as buildings throughout the city shuddered and crashed to the ground……http://www.tomdispatch.com/blog/176032/     http://atimes.com/2015/08/entering-the-nuclear-age-body-by-body-the-nagasaki-experience/
