## How many tonnes of TNT was Hiroshima?

The explosive effect of each was equal to that of up to a few tens of thousand tonnes of the conventional explosive TNT.

On this basis of comparison, the Hiroshima bomb was of about 15 kilotons – that is, of 15 thousand tonnes of TNT equivalent – and that at Nagasaki was of 25 kilotons (ca..

## How many tons of TNT was the first nuclear bomb?

“The first atomic bomb, or A-bomb, exploded on July 16, 1945, Alamogordo, N. Mex. It produced an explosion equal to that of 19,000 short tons (17,000 metric tons) of TNT.”

## What happens if you nuke the moon?

Depending on where the detonation happened, sending the moon careening away from Earth would take somewhere between 10 billion and 10 trillion megatons of TNT. The most powerful nuclear device ever detonated, the Soviet Union’s “Tsar Bomba,” yielded the energy equivalent of 50 megatons of TNT.

## What is the most powerful nuke?

Tsar BombaTsar Bomba, (Russian: “King of Bombs”) , byname of RDS-220, also called Big Ivan, Soviet thermonuclear bomb that was detonated in a test over Novaya Zemlya island in the Arctic Ocean on October 30, 1961. The largest nuclear weapon ever set off, it produced the most powerful human-made explosion ever recorded.

## What’s the largest nuclear bomb that could be built?

Tsar BombaTsar BombaMass27,000 kg (60,000 lb)Length8 m (26 ft)Diameter2.1 m (6 ft 11 in)Blast yield50 megatons of TNT (210 PJ)9 more rows

## How many tons of TNT would destroy Earth?

It basically boils away the whole Earth. The gravitational binding energy of Earth is about 2.2*10 32 J, corresponding to 5*10 22 tons of TNT. The largest weapon tested so far (Tsar bomba) had 50 megatons, we would need 10 15 or 1 quadrillion of them.

## How many pounds of TNT are in a kiloton?

Learn about this topic in these articles: atomic bombs is measured in kilotons, each unit of which equals the explosive force of 1,000 tons of TNT. The explosive power of hydrogen bombs, by contrast, is frequently expressed in megatons, each unit of which equals the explosive force of 1,000,000 tons of TNT.

## How many nukes will it take to end the world?

New research argues that 100 nuclear weapons is the “pragmatic limit” for any country to have in its arsenal. Any aggressor nation unleashing more than 100 nuclear weapons could ultimately devastate its own society, scientists warn.

## Is Hiroshima still radioactive?

Among some there is the unfounded fear that Hiroshima and Nagasaki are still radioactive; in reality, this is not true. Following a nuclear explosion, there are two forms of residual radioactivity. … In fact, nearly all the induced radioactivity decayed within a few days of the explosions.
