Nuclear Weapons

1. prompt radiation is emitted at the time of detonation and propagates in straight lines from the fireball in all directions; prompt radiation is neutrons, gamma rays, x-rays, UV, light, IR, with smaller amounts of microwave and radio waves
2. delayed radiation is mostly in the form of fallout and spreads by the winds (in an atmospheric detonation), water currents (in an underwater detonation), or by following the earth's magnetic field lines (in a detonation in space; delayed radiation is mostly alpha, beta, and gamma rays

Yes, a Thermonuclear Weapon (or Hydrogen Bomb) contains a core of Plutonium-239 and Uranium-235.

A hydrogen bomb (thermonuclear fusion device) is triggered by a conventional thermonuclear fission bomb, and therefore has a core of fissionable materials such as U-235 and Pu-239.

The fission device acting as a trigger is in turn triggered by conventional chemical explosives.

Seek shelter immediately in a building made of concrete or underground, as this can help reduce exposure. Remove contaminated clothing and wash your body using soap and water to remove radioactive particles. Follow any instructions or evacuation orders given by authorities.

As an informal unit of time in nuclear physics, a shake is 10 nanoseconds or 10^-8 of a second.

The uranium used for the atomic bomb was primarily sourced from the Congo and later from mines in the US. The uranium ore was then processed to extract the isotope U-235 necessary for nuclear fission to create the bomb.

When an earthquake hits a nuclear power plant the plant explodes and releases radiation. People must evacuate within 100-200 miles or less. They must have helicopters fly in the air and put down, Swiss cheese shaped platforms and drop medal rods through the holes. Then the rods absorb the radiation and reduce it. Or they keep on pouring water into the plant, Otherwise there will be a meltdown

Nuclear radiation doesn't affect the ocean itself, but the animals that live there. Just like any living thing, if an ocean animal is exposed to high level of radiations it might develop mutations, and/or cancer, leading to a painful death.

Unless we do it to ourselves out of sheer stupidity, it won't happen for another 5 billion years or so. But the earth will become completely uninhabitable one or two billion years before that. Better book your flight early.

If a nuclear weapon were to hit Earth's core, it would likely cause catastrophic damage, potentially leading to widespread earthquakes, tsunamis, and volcanic eruptions. The explosion would disrupt the delicate balance of forces that keeps the core stable, with devastating consequences for the planet's geological processes and possibly triggering a mass extinction event.

No, nuclear weapons do not have the capability to destroy the entire Earth. While they have devastating power and can cause widespread destruction, they are not capable of wiping out the entire planet.

Each country must assess the risks and benefits of having nuclear power stations based on their specific circumstances. While earthquake prone countries can pose higher risks for nuclear accidents, careful planning, safety measures, and technology advancements can help mitigate these risks. It is important for these countries to have robust safety regulations and emergency procedures in place to ensure the safe operation of nuclear power stations.

It would require an immense amount of uranium, far beyond what is accessible on Earth, to detonate the planet. The idea of destroying Earth with uranium or any other material is simply not feasible with current technology.

The most destructive weapon on earth is the hydrogen bomb. These weapons are potentially thousands of times more powerful than ordinary atom bombs (which use nuclear fission rather than fusion) and could easily destroy a city in seconds.

On the surface no nuclear explosion no matter the yield could do it, the atmosphere provides insufficient tamping for this and would simply be blown away into space above ground zero. To get enough tamping, the explosion would have to be very deep subsurface, probably hundreds of miles or more into the mantle. We can't drill a hole that deep.

The biggest bomb was the Tsar bomba, it used around 50MT (megatons) of TNT which is the same as all bombs dropped in WW2 times 10x, it was capable of destroying 30-40 miles of territory without any large deposits of radiation.

Uranium typically needs to be enriched to around 90% U-235 to be used in a nuclear bomb. This high level of enrichment allows for a sustained nuclear chain reaction and efficient weapon detonation.

Nuclear explosions can have devastating effects on the environment, including radioactive fallout, destruction of ecosystems, and long-term health impacts on humans and wildlife. The release of radioactive materials can contaminate soil, water, and air, leading to widespread and long-lasting environmental damage. Efforts are made to contain and mitigate these effects, but the environmental impact of nuclear explosions can persist for generations.

This is an example of an arms control agreement, specifically the Comprehensive Nuclear-Test-Ban Treaty (CTBT). The treaty aims to prevent the testing of nuclear weapons and the spread of nuclear weapons technology, contributing to global nuclear non-proliferation efforts.

An underground nuclear detonation creates a crater in the Earth's surface. The explosion occurs beneath the ground, causing the soil and rock to be displaced upwards, resulting in a visible crater above the detonation point.

The core of the Ivy King device used Highly Enriched Uranium-235 as the fissile material.

The Ivy King device was designed by the Los Alamos National Laboratory under the leadership of physicist Richard Garwin.

The "Ivy King" shot conducted by the United States in 1952 had a yield of 500 kilotons. This test was part of Operation Ivy, a series of nuclear tests.

About 64 kilograms- but only about 600 milligrams was converted to energy. See the link below for a good article on Little Boy.
