A hydrogen bomb has never been used in battle by any country, but experts say it has the power to wipe out entire cities and kill significantly more people than the already powerful atomic bomb, which the U. More than , people died in Japan after the U.
The bombings in the two cities were so devastating, they forced Japan to surrender. But a hydrogen bomb has the potential to be 1, times more powerful than an atomic bomb, according to several nuclear experts.
The U. Hydrogen bombs cause a bigger explosion, which means the shock waves, blast, heat and radiation all have larger reach than an atomic bomb, according to Edward Morse, a professor of nuclear engineering at University of California, Berkeley.
Although no other country has used such a weapon of mass destruction since World War II, experts say it would be even more catastrophic if a hydrogen bomb were to be dropped instead of an atomic one. Simply speaking, experts say a hydrogen bomb is the more advanced version of an atomic bomb. An atomic bomb uses either uranium or plutonium and relies on fission, a nuclear reaction in which a nucleus or an atom breaks apart into two pieces.
To make a hydrogen bomb, one would still need uranium or plutonium as well as two other isotopes of hydrogen, called deuterium and tritium. Although the destruction at Nagasaki has generally received less worldwide attention than that at Hiroshima, it was extensive nonetheless. Almost everything up to half a mile from ground zero was completely destroyed, including even the earthquake-hardened concrete structures that had sometimes survived at comparable distances at Hiroshima.
According to a Nagasaki Prefectural report "men and animals died almost instantly" within 1 kilometer 0. Almost all homes within a mile and a half were destroyed, and dry, combustible materials such as paper instantly burst into flames as far away as 10, feet from ground zero.
Of the 52, homes in Nagasaki, 14, were destroyed and 5, more seriously damaged. Only 12 percent of the homes escaped unscathed. The official Manhattan Engineer District report on the attack termed the damage to the two Mitsubishi plants "spectacular. Fire-fighting efforts were hampered by water line breaks, and six weeks later the city was still suffering from a shortage of water. Navy officer who visited the city in mid-September reported that, even over a month after the attack, "a smell of death and corruption pervades the place.
As with the estimates of deaths at Hiroshima, it will never be known for certain how many people died as a result of the atomic attack on Nagasaki. The best estimate is 40, people died initially, with 60, more injured. By January , the number of deaths probably approached 70,, with perhaps ultimately twice that number dead total within five years.
For those areas of Nagasaki affected by the explosion, the death rate was comparable to that at Hiroshima. The day after the attack on Nagasaki, the emperor of Japan overruled the military leaders of Japan and forced them to offer to surrender almost unconditionally. Sources and notes for this page.
