Mushroom clouds haunt mankind for 72 years

In the past 72 years, countries have conducted more than 2,000 nuclear weapons tests with greater destructive power than any weapon ever known in human history.

The first atomic bomb test of a man named "Trinity" in New Mexico, USA on July 16, 1945.The "Trinity" bomb test opened the nuclear era, giving birth to the most destructive weapon in human history.Almost a month later, the world's first atomic bomb was dropped on Hiroshima on August 6, 1945, killing more than 100,000 people.(Photo: Getty).

US nuclear bomb test at Bikini Atoll, coral reef in Oceania in 1946. To date, more than 2,000 nuclear weapons tests have been conducted in the world.The United States is the country with the largest number of nuclear tests with 1,054 cases.The following are the Soviet, British, French, and other countries respectively.(Photo: Getty).

The first successful nuclear bomb test of the Soviet Union, codenamed "First Lightning", was executed on August 29, 1949.The RDS-1 bomb had 22 kilotons of bombs (equivalent to 22,000 tons of TNT), causing a 50% greater destruction than Soviet scientists calculated.The nuclear race between the US and the Soviet Union has repeatedly pushed the world to the brink of nuclear war.(Photo: Getty).

The US "Castle" codename nuclear test at Bikini Atoll in 1954. The bomb destroyed 15,000 kilotons (equivalent to 15,000 tons of TNT) 1,000 times stronger than the Hiroshima bomb.This is the 3rd most powerful bomb in human history.The two most powerful bombs in the world were tested by the Soviet Union in 1961 (50,000 kilotons) and in 1962 (24,200 kilotons).(Photo: Getty).

The French nuclear bomb test at Bikini Atoll, Oceania in 1957. In an effort to prevent nuclear war, the "Partial Nuclear Test Ban Treaty" was signed in 1963 with 126 members. including the US and the Soviet Union.This international treaty was quickly violated by great powers.(Photo: Getty).

China's first successfully tested nuclear bomb on October 16, 1964 in Takala Makan desert, Xinjiang.The trend of diminishing nuclear weapons testing has emerged since the Cold War.He was the first country to stop testing nuclear weapons in 1991. The United States has not tested nuclear weapons since 1992. The last test of French and Chinese nuclear weapons took place in 1996. (Photo : Getty).

The nuclear bomb test with the 34 kilotons of French bombardment at Aopuni, Oceania on January 1, 1971.There are 8 countries that claim to have nuclear weapons including the US, Russia, China, Britain, France, India, Pakistan and North Korea.The total number of nuclear warheads in the eight countries holding is about 15,600 warheads, most of which belong to Russia (7,000 warheads) and the United States (6,800 warheads).Israel is said to own 80 nuclear warheads, although it has never acknowledged its nuclear capabilities.(Photo: Getty).

Seoul people follow the news of Pyongyang's nuclear test on September 9, 2016.Korea is the most recent country to test nuclear weapons.Scientists calculate that only 100 small-sized nuclear warheads (less than 50 kilotons) can kill 2 billion people and bring the Earth to a nuclear winter for at least 25 years.2 billion others will die from hunger as a result of nuclear winter.(Photo: Getty).
