What can nuclear weapons do to humans?
A nuclear weapon would cause great destruction, death, and injury and have a wide area of impact. People close to the blast site could experience: Injury or death (from the blast wave) Moderate to severe burns (from heat and fires)
How far can nuclear weapons travel?
North Korea’s Hwasong-14 has a potential range of 8,000km – although some studies suggested it could travel as far as 10,000km if fired on a maximum trajectory. This would give Pyongyang its first truly intercontinental ballistic missile, capable of reaching New York.
How big are nukes now?
Nuclear weapons vary in their destructive power. In the United States’ current nuclear arsenal, the most powerful bomb is the B83, which has a maximum yield of 1.2 megatons, making it 60 times more powerful than the bomb dropped on Nagasaki, Japan, in 1945.

The immediate blast would stretch more than half a mile in all directions, incinerating people, buildings – everything inside the explosion, immediately. Those up to five miles outside of it could suffer third-degree burns, and those up to seven miles away would experience second and first degree-burns.
How big is a nuclear bomb?
Nuclear bombs have had yields between 10 tons TNT (the W54) and 50 megatons for the Tsar Bomba (see TNT equivalent). A thermonuclear weapon weighing as little as 600 pounds (270 kg) can release energy equal to more than 1.2 megatonnes of TNT (5.0 PJ).
How much does a nuke weigh?
When was the last nuclear war?
To date, the only use of nuclear weapons in armed conflict occurred in 1945 with the American atomic bombings of Hiroshima and Nagasaki.
How tall is a nuclear missile?
In order to cover large distances, ballistic missiles are usually launched into a high sub-orbital spaceflight; for intercontinental missiles, the highest altitude (apogee) reached during free-flight is about 2,000 kilometers (1,200 mi).
How long do nuclear weapons last?
Seven hours after a nuclear explosion, residual radioactivity will have decreased to about 10 percent of its amount at 1 hour, and after another 48 hours it will have decreased to 1 percent.

How far can nukes travel?
The light from a nuclear explosion can cause flash blindness – a temporary form of vision loss that can last a few minutes. According to AsapSCIENCE’s video, a one-megaton bomb, 80 times larger than the bomb detonated over Hiroshima in 1945, can affect people up to 13 miles away.
How fast do nukes travel?
about 15,000 mph
All of the intercontinental ballistic missiles in the world’s nuclear arsenals are hypersonic, reaching about 15,000 mph (24,140 kph), or about 4 miles (6.4 km) per second at their maximum velocity.
Could a nuke cause a tsunami?
The tests revealed that a single explosion would not produce a tsunami, but concluded that a line of 2,000,000 kg (4,400,000 lb) of explosives about 8 km (5.0 mi) off the coast could create a destructive wave.
