Which is more powerful hydrogen or atomic bomb?
A Hydrogen bomb is way more powerful than a atomic bomb. Hydrogen bombs can get up to 50 megatons of TNT which is more than 5,000 times more powerful than a single atomic bomb. While an atom bomb gets it's energy from fission-or splitting of an atom a hydrogen bomb uses the fusion of atom.
The bomb itself (unexploded) will emit minor amount of radiation from the uranium or plutonium trigger. Fusing hydrogen (or deuterium or tritium) doesn't produce radioactive fallout, but fissioning uranium does. So a higher yield from fission will produce more fallout, which will produce more radioactivity.
Pakistan thus became the seventh country in the world to successfully develop and test nuclear weapons. Although, according to a letter sent by A.Q. Khan to General Zia, the capability to detonate a nuclear bomb using highly enriched uranium as fissile material produced at KRL had been achieved by KRL in 1984.
A group of scientists led by Edward Teller supported its development. They made direct approaches to the military and the Joint Committee on Atomic Energy. In 1950, President Harry S. Truman announced work on the hydrogen bomb was to continue.
The bombings in the two cities were so devastating, they forced Japan to surrender. But a hydrogen bomb has the potential to be 1,000 times more powerful than an atomic bomb, according to several nuclear experts.
Thermonuclear bombs start with the same fission reaction that powers atomic bombs — but the majority of the uranium or plutonium in atomic bombs actually goes unused. In a thermonuclear bomb, an additional step means that more of the bomb's explosive power becomes available.
The hydrogen bomb, also called the thermonuclear bomb, uses fusion, or atomic nuclei coming together, to produce explosive energy. Stars also produce energy through fusion. What's the same: Both the A-bomb and H-bomb use radioactive material like uranium and plutonium for the explosive material.
In Pictures: The World's Most Nuclear Nations. With 104 operating reactors, the United States produces more electricity with nuclear power than any of the 30 countries with that capability. In fact, it generates about the same amount of nuclear energy as the next largest producers, France and Japan, combined.
Last Updated: April, 2016. In the mid-1970s Pakistan embarked upon the uranium enrichment route to acquire a nuclear weapons capability. Pakistan conducted nuclear tests in May 1998, shortly after India's nuclear tests, declaring itself a nuclear weapon state.
The exact number of nuclear warheads is a state secret and is therefore a matter of guesswork. The Federation of American Scientists estimates that Russia possesses 4,300 nuclear warheads, while the U.S. has 4,000; Russia has 1,950 active strategic nuclear warheads, compared with the U.S. having 1,650.
Nuclear weapons and Israel. Israel is widely believed to possess nuclear weapons, with an estimated arsenal of up to 400 warheads; which would make it the world's third biggest arsenal.
Israel is widely believed to possess weapons of mass destruction, and to be one of four nuclear-armed countries not recognized as a Nuclear Weapons State by the Non-Proliferation Treaty (NPT).
On January 5, 2015, North Korean TV news anchors announced that they had successfully tested a "miniaturized atomic bomb", about 5 miles from the Punggye-ri nuclear site where a test was conducted in 2013. On January 6, 2016, North Korea announced that it conducted a successful test of a hydrogen bomb.
Tsar Bomba (RDS-220 hydrogen bomb) – 50Mt. The RDS-220 hydrogen bomb, also known as the Tsar Bomba, is the biggest and most powerful thermo nuclear bomb ever made. It was exploded by the Soviet Union on 30 October 1961 over Novaya Zemlya Island in the Russian Arctic Sea.
The People's Republic of China has developed and possesses weapons of mass destruction, including chemical and nuclear weapons. The first of China's nuclear weapons tests took place in 1964, and its first hydrogen bomb test occurred in 1967.
But after the Soviets successfully detonated an atomic bomb in 1949, President Harry S. Truman ordered the creation of a hydrogen bomb project. With the help of the Polish mathematician Stanislaw Ulam, Dr. Teller developed a model for the hydrogen bomb known as the Teller-Ulam design.
How many nuclear weapons are there in the world?

The report's mid-range estimate was that North Korea had 16 nuclear bombs at the end of last year and could have 50 by 2020. This assumes that the North Koreans continue nuclear tests every three to four years, improve their bomb design skills, and get some limited assistance from Iran.
Though India has not made any official statements about the size of its nuclear arsenal, recent estimates suggest that India has 110 nuclear weapons — consistent with earlier estimates that it had produced enough weapons-grade plutonium for up to 75–110 nuclear weapons.
