Does a nuclear bomb blow up on contact with the ground?

A nuclear bomb blows up when critical mass is reached. Critical mass is some amount (depending on the fuel--uranium, plutonium--and how pure the material is. A nuclear bomb typically has two pieces of the fuel, one in the head of the bomb and one near the tail. when the bomb hits the ground, the piece from the tail slides forward to combine with the piece at the head.

First, a nuclear bomb designed as above could not work, all it would do is heat the two pieces of fissile material to melting point before they touched causing a "fizzle" yield explosion accomplishing nothing but scattering molten fissile material around the area producing significant alpha emitter radiological contamination. Any nuclear bomb requires explosives to "assemble" the piece(s) fast enough to supercritical condition and prevent a "fizzle" yield.

A nuclear bomb (as any other bomb) blows up when triggered by its fuse. There are many types of fuses:

  • altitude - this fuse is for airbursts, when the fuse determines the bomb has fallen to the set altitude the fuse blows up the bomb
  • contact - this fuse is for surface bursts, typically when an accelerometer in the fuse detects sudden deceleration the fuse blows up the bomb
  • depth - this fuse is for subsurface bursts (underground or underwater), when the fuse determines the bomb reaches the set depth the fuse blows up the bomb (underground bursts are either for cratering or destroying hardened installations like missile silos, underwater bursts are usually for destroying submarines)
  • lay down - this fuse is for low altitude precision delivery by airplane to let the airplane escape the blast, the bomb is dropped by parachute when an accelerometer in the fuse detects sudden deceleration the fuse starts a short delay timer, the parachute gently lays the bomb down on its side on the ground, when the delay timer runs out the fuse blows up the bomb
  • time delay - this fuse is designed to let the bomb bury itself underground where it "hides", on impact the fuse starts the timer which may be set for hours to months or even longer, when the timer runs out the fuse blows up the bomb
  • vibration - this fuse is designed not to blow up the bomb unless it is disturbed, then an accelerometer or "tilt switch" mechanism triggers the fuse to blow up the bomb
  • booby trap - this fuse is designed only to blow up the bomb if someone is actively attempting to disarm the bomb
  • etc.

How many hydrogen bombs have been tested?

Cannot be determined as for some test shots the testing nation still considers the type to be classified information. And with underground testing nobody else can determinee type by fallout isotope tests.

What kind of energy conversions takes place in a nuclear bomb explosion?

In a nuclear bomb explosion, the energy conversion involves the release of nuclear energy through the process of nuclear fission or fusion. This energy is then converted into thermal energy (heat), light energy (flash of light), and mechanical energy (shockwave). The explosion results from the rapid release of this energy.

What was the joint research for 1940 nuclear bomb called?

The joint research effort to develop the nuclear bomb during World War II was called the Manhattan Project. It was a top-secret program led by the United States with contributions from the United Kingdom and Canada. The project resulted in the successful testing and subsequent use of nuclear weapons on Hiroshima and Nagasaki in 1945.

What is the core heat of a nuclear explosion?

Several million degrees, hot enough to glow intensely enough in x-rays to make air opaque to visible light. This x-ray glow can be channeled to a fusion stage to set it off, that can get to several tens of millions of degrees.

How do you disarm nuclear weapon?

That would really depend on the design of the weapon:

  • Early US bombs were armed and disarmed by manually inserting and removing the fissile core.
  • Some later US bombs were armed by manually or automatically pulling a chain or wire out of the fissile core, they could not be disarmed.
  • Modern US bombs and warheads are armed with a cryptographic code entered into the PAL, I am not sure about disarming but suspect the PAL handles it too.
  • Other countries may use entirely different systems or none at all.

There is usually also an entirely separate system for arming and disarming the chemical explosives component.

Are nukes radioactive?

Yes, nuclear weapons or nuclear reactors produce radiation as a byproduct of nuclear reactions. This radiation can be in the form of gamma rays, alpha particles, or beta particles. Therefore, exposure to nuclear weapons or the fallout from a nuclear explosion can result in harmful levels of radiation.

When was implosion style nuclear device tested?

The first implosion-style nuclear device was tested on July 16, 1945, as part of the Trinity test in New Mexico, USA. This test marked the first successful detonation of a nuclear weapon.

What is the code name for the first nuclear weapons test?

The code name for the first nuclear weapons test was "Trinity." It took place on July 16, 1945, in the New Mexico desert as part of the Manhattan Project.

Did Albert Einstein help design the atom bomb?

No, Albert Einstein did not help design the atom bomb. He was a theoretical physicist who wrote a letter to President Franklin D. Roosevelt urging him to research nuclear technologies, which indirectly led to the Manhattan Project that developed the atomic bomb.

What are the properties and pros and cons of using plutonium?

Why are nuclear bombs more destructive than convectional bombs?

Nuclear bombs release energy from the nucleus of the atom, which is held together by the Strong Force. Conventional bombs release energy from the electron cloud of the atom, which is held to the nucleus by the Electromagnetic Force. The Strong Force is thousands of times stronger than the Electromagnetic Force and thus releases thousands of times as much energy.

What is the cost price of a nuclear weapon grade uranium?

The cost of nuclear weapon grade uranium can vary greatly depending on factors such as market conditions, quantity purchased, and source of the material. However, it is generally estimated to be in the range of tens of thousands to hundreds of thousands of dollars per kilogram.

Can thorium be used in a nuclear bomb?

Yes, thorium can be used as a nuclear fuel in certain types of reactors, but it is not typically used in nuclear weapons. Uranium and plutonium are the primary materials used in nuclear bombs due to their ability to sustain nuclear fission reactions and to release large amounts of energy quickly.

What are the reasons why you should not use nuclear power?

Some of the reasons that we should not use nuclear power are, although it is a effective way to create a large amount of power in a short time and at relatively low initial cost, the proses of nuclear fission in which the nuclei of a group of uranium 265 atoms are split by an electron creating a chain reaction, has many disadvantages. For one, the radiation is very damaging, and it creates radioactive waste that is a devil to clean up properly. And if we were to rely on it, we would eventually have to switch to other mens because it uranium decays.

Are there nuclear power plants in Texas?

  1. Comanche Peak Nuclear Power Plant, Unit 1 - Glen Rose, TX
  2. Comanche Peak Nuclear Power Plant, Unit 2 - Glen Rose, TX
  3. South Texas Project, Unit 1 - Bay City, TX
  4. South Texas Project, Unit 2 - Bay City, TX

There are 104 plants licensed to operate in the US currently.

How much plutonium used in nuclear bomb?

In the Nagasaki bomb, about 14 pounds. Design criteria on later weapons is classified.

How many nukes would it take to blow up the world?

It is impossible to blow up the world with nuclear weapons. The detonation of all nuclear weapons on Earth would not have enough energy to physically destroy the planet. However, the global consequences would be catastrophic, leading to nuclear winter, widespread destruction, and loss of life.

Was Einstein involved in creating the nuclear bomb?

Other than writing the letter to Roosevelt at the request of Leo Szilard (who held the Nuclear Chain Reaction patent already), which got Roosevelt to begin a study committee with a budget of $6000, Einstein did not participate. Eventually the committee recommended starting a full development program, which became the Manhattan Project.

What makes up a nuclear bomb?

Depends on the type of bomb. The first nuclear weapons were fission weapons- they used a heavy metal such as Uranium or Plutonium. These metals, when compressed by explosives, would undergo nuclear fission, and break into lighter elements, releasing heat and radiation. Later, larger bombs were fusion bombs. They used a fission bomb to start the nuclear reaction, but then used that energy to FUSE light elements, such as Deuterium and Tritium into heavier elements, releasing LARGE amounts of heat and radiation.

What would be the fallout area if Chicago were hit with a nuclear bomb?

The fallout area of a nuclear bomb is influenced by factors such as bomb size, altitude of detonation, and prevailing winds. In the case of a nuclear bomb hitting Chicago, the fallout area could potentially cover a wide radius depending on these factors, resulting in devastating consequences for both the city and surrounding areas. Evacuation and sheltering would be crucial for minimizing exposure to radiation.

Can a nuke destroy a country?

Yes. 70,000 people were instantly killed at Hiroshima. Another 70,000 at Nagasaki, 3 days later. Nukes can easily wipe away big islands. Basically, nuclear bombs make extremely powerful reactions that release TONS of energy and they could easily wipe away A LOT of land.

Why is plutonium in a nuclear power sation?

Plutonium is used in nuclear power stations as a fuel in some types of reactors, like fast breeder reactors. It can undergo fission to produce energy. Additionally, plutonium can be created as a byproduct in nuclear reactors, which can then be reprocessed and reused as fuel.

What is the meaning of nuclear power please tell you?

Nuclear power refers to the process of generating electricity using nuclear reactions to produce heat. This heat is used to create steam, which drives turbines connected to generators, producing electricity. Nuclear power is a low-carbon energy source but comes with concerns related to nuclear waste disposal, safety, and potential accidents.
