What is the detonation velocity of nuclear bomb?

What is the detonation velocity of nuclear bomb?

High explosives detonate with explosive velocity of about 3–9 kilometres per second (9,800–29,500 ft/s). For instance, TNT has a detonation (burn) rate of approximately 5.8 km/s (19,000 feet per second), detonating cord of 6.7 km/s (22,000 feet per second), and C-4 about 8.5 km/s (29,000 feet per second).

What is the safe distance from a nuclear explosion?

Survive DURING When you have reached a safe place, try to maintain a distance of at least six feet between yourself and people who are not part of your household. If possible, wear a mask if you’re sheltering with people who are not a part of your household.

How does nuclear detonation work?

Modern nuclear weapons work by combining chemical explosives, nuclear fission, and nuclear fusion. The explosives compress nuclear material, causing fission; the fission releases massive amounts of energy in the form of X-rays, which create the high temperature and pressure needed to ignite fusion.

Are nuclear bombs radioactive before detonation?

There are several kinds of radiation emitted; these types include gamma, neutron, and ionizing radiation, and are emitted not only at the time of detonation (initial radiation) but also for long periods of time afterward (residual radiation). …

What is the most powerful explosive?

One of the most powerful explosive chemicals known to us is PETN, which contains nitro groups which are similar to that in TNT and the nitroglycerin in dynamite. But the presence of more of these nitro groups means it explodes with more power.

Which is an example of a nuclear detonation?

Nuclear Detonation: General Information The energy released in a nuclear explosion derives from the splitting (fission) of radioactive materials, e.g. Bombs dropped on Hiroshima and Nagasaki, Japan at the end of World War II are examples of nuclear explosions.

What are the immediate effects of a nuclear explosion?

Immediate effects (blast, thermal radiation, prompt ionizing radiation) are produced and cause significant destruction within seconds or minutes of a nuclear detonation.

Who was the first country to detonate an atomic bomb?

On July 16, 1945, the United States became the first country to successfully detonate an atomic weapon, signalling the beginning of a new era in warfare and in politics. In the early 1940s, the U.S. government authorized a top-secret program of nuclear testing and development, codenamed “The Manhattan Project”.

Can a stolen nuclear weapon cause an explosion?

An illicit nuclear weapon bought, stolen, or otherwise originating from a nuclear state, or a weapon fabricated by a terrorist group from illegally obtained fissile nuclear weapons material that produces a nuclear explosion Built from the components of a stolen weapon or from scratch using nuclear material (plutonium or highly enriched uranium)
