do nuclear bombs leave radiation?

Nuclear weapons emit large amounts of thermal radiation as visible, infrared, and ultraviolet light, to which the atmosphere is largely transparent. This is known as "Flash". The chief hazards are burns and eye injuries. On clear days, these injuries can occur well beyond blast ranges, depending on weapon yield.

Ionizing radiation, such as X-rays and gamma rays, is a high-energy kind of radiation that causes ions and free radicals to form. These ions and free radicals can go on to break covalent bonds in other molecules, such as DNA.

Nuclear explosions produce air-blast effects similar to those produced by conventional explosives. The shock wave can directly injure humans by rupturing eardrums or lungs or by hurling people at high speed, but most casualties occur because of collapsing structures and flying debris. Thermal radiation.

Source. The commonly used sources of radiation are cobalt-60, a radioactive element emitting γ-rays, or an accelerator producing a beam of electrons. Cobalt-60 is produced by neutron bombardment of stable cobalt in a nuclear reactor. ... Cobalt-60 decays continuously.

Gamma radiation, unlike alpha or beta, does not consist of any particles, instead consisting of a photon of energy being emitted from an unstable nucleus. Having no mass or charge, gamma radiation can travel much farther through air than alpha or beta, losing (on average) half its energy for every 500 feet.

Nuclear radiation. Alpha, Beta and Gamma radiation all have different properties and effects. Radiation can have destructive effects but can also be used in medicine, industry and electricity generation.

Since energy levels in the nucleus are much higher than those in the gas, the nucleus will cool down by emitting a more energetic electromagnetic wave called a gamma ray . Gamma ray emission causes no change in the number of particles in the nucleus meaning both the atomic number and mass number remain the same.

The Effects of Nuclear Weapons Blast, thermal radiation, and prompt ionizing radiation cause significant destruction within seconds or minutes of a nuclear detonation. The delayed effects, such as radioactive fallout and other environmental effects, inflict damage over an extended period ranging from hours to years.

Gamma rays are produced when radioactive elements decay. Radioactive elements are elements with unstable nuclei. To become more stable, the nuclei undergo radioactive decay. In this process, the nuclei give off energy and may also emit charged particles of matter.

Gamma radiation or gamma rays are high-energy photons that are emitted by radioactive decay of atomic nuclei. Gamma radiation is very high-energy form of ionizing radiation, with the shortest wavelength.

Nuclear fission produces the atomic bomb, a weapon of mass destruction that uses power released by the splitting of atomic nuclei. When a single free neutron strikes the nucleus of an atom of radioactive material like uranium or plutonium, it knocks two or three more neutrons free.

How does a Nuclear Bomb differ from a Conventional Bomb? A conventional bomb releases most of its energy in the form of blast. Atomic bombs on the other hand, release 50 per cent energy as blast, 35 per cent as heat and 15 per cent as nuclear radiation.

It's more or less safe to live in Hiroshima and Nagasaki because the fallout from the bombs has long since dissipated to safe levels. The majority of the fuel in the bombs didn't actually undergo fission, so not as much radioactive particles were released as there could have been.

When added to the dust of radioactive material released by the bomb itself, a large amount of radioactive material is released into the environment. This form of radioactive contamination is known as nuclear fallout and poses the primary risk of exposure to ionizing radiation for a large nuclear weapon.

Radiation-induced cancers will affect many, often over twenty years later. Nuclear weapons cause severe damage to the climate and environment on a scale incomparable to any other weapon: the Red Cross estimates that a billion people around the world could face starvation as a result of nuclear war.

Finally, regarding the long-term effects of a nuclear weapon detonating in space, that radioactive material falling into the atmosphere isn't going anywhere. In fact, it dissipates and spreads around the entire planet.

Atomic bombs are made up of a fissile element, such as uranium, that is enriched in the isotope that can sustain a fission nuclear chain reaction. When a free neutron hits the nucleus of a fissile atom like uranium-235 (235U), the uranium splits into two smaller atoms called fission fragments, plus more neutrons.
