That depends on the initial amount and type. It also depends on altitude (or depth) of burst. If you know the isotopes involved you can look up their half lives, measure current radiation intensity, and calculate time until radiation will drop to desired level.
You can also periodically measure radiation intensity over a period of time, then extrapolate to get a reasonable estimate of time to drop to desired level without knowing isotopes.

Do South Africa possess atomic bomb?
No, South Africa long ago gave up its nuclear weapons program.
Why is an atomic bomb called a nuke?
Well I am pretty sure they call an atomic bomb nukes because atomic bombs and be called nuclear bombs. So instead of calling these super long name they made the bomb a short nick name a nuke
How long after a neutron bomb blast does the radiation last?
After a neutron bomb blast, the immediate radiation from the explosion is intense but short-lived, primarily consisting of neutron and gamma radiation. Most of the harmful radiation dissipates within a few hours to a few days, but residual radiation from fallout can persist for weeks to years, depending on the environment and the amount of fallout produced. The high-energy neutrons are particularly effective at penetrating materials, so areas near the blast may require extended periods before being deemed safe for human habitation.
What was the name of the Soviet nuclear power plant that exploded and is considered to be the greatest nuclear disaster ever?
Chernobyl. And while it IS regarded as the worst nuclear disaster, in terms of long-term consequences, we are actually begining to discover that many of the supposedly radiation-caused illnesses are actually the result of an extremely high level of impurities, especially Lead in the water supply, and not actually the result of radiation poisoning as originally suspected. But, the jury is not in just yet.
What does an atom bomb do?
Without going into rigorous scientific detail, an atomic bomb works by nuclear fission. That is, large atoms - namely uranium or plutonium - are split into smaller atoms in an uncontrolled chain reaction. One atom splits, neutrons from that split strike and split more atoms, which release more neutrons, and so forth, in what is called a chain reaction. This releases a tremendous amount of energy all at once. Thus a single bomb, weighing no more than a few hundred pounds, explodes with the force of tens of thousands of tons of TNT.When we look at a hydrogen bomb, which is also a type of nuclear weapon (though strictly not an atomic bomb), we see that it works by nuclear fusion. That is small atoms - namely isotopes of hydrogen - are fused together to make atoms of helium. This releases even more energy. Thus a hydrogen bomb has a force of hundreds of thousands, or even millions of tons of TNT. Fusion requires fantastic temperatures and pressures to occur. The only way to create those conditions is to set off one or more atomic fission bombs. Essentially, a hydrogen bomb is a nuclear fusion device that requires an fission bomb as a detonator.Both types of bombs produce several effects: a blast wave, thermal (heat) energy, prompt (i.e. immediate) radiation, and fallout (long-term radiation), as well as intense electromagnetic disruption. The exact amount of each depends on the design of the weapon, its size, and where it was detonated.For the more detailed technical answer, use the link you'll find below for the related question.
Does a nuclear bomb have radiation in it?
Yes, a nuclear bomb produces radiation as a result of the nuclear fission or fusion reactions that release large amounts of energy. This radiation can have immediate and long-term harmful effects on living organisms and the environment.
What are negative effects of Nuclear bomb?
Long Term effects due to radiation Massive Damage to buildings Radioactive area where the bomb exploded
Does a nuclear bomb hurt?
A nuclear bomb causes immense destruction and loss of life due to the intense heat, blast wave, and radiation it produces. It can kill and injure thousands of people within seconds and have long-term health effects on survivors due to radiation exposure. The impact of a nuclear bomb can be devastating to both the immediate area and the environment.
What can the nuclear bomb do?
A nuclear bomb has the potential to cause massive destruction and loss of life through its explosive power and radiation effects. The blast creates a powerful shockwave and heat, causing widespread damage. The resulting radiation can also have long-term health consequences for those exposed.
What is the radiation of a nuclear bomb?
The radiation from a nuclear bomb includes gamma rays, neutrons, and residual radioactive fallout. Gamma rays are high-energy electromagnetic radiation, while neutrons are subatomic particles that can induce nuclear reactions in surrounding materials, releasing additional radiation. Fallout consists of radioactive particles and debris from the explosion that can spread over large areas, causing long-term contamination.
How many people does a nuclear bomb kill?
The number of people killed by a nuclear bomb depends on various factors such as the size of the bomb, the distance from the blast, and the preparedness of the population. A single nuclear bomb has the potential to kill hundreds of thousands to millions of people instantly or through long-term effects like radiation exposure.
Why used nuclear bombs at war time?
They're very destructive and last for a long time, In other words, once you've blown up a nuclear bomb somewhere, it will still be dangerous after the initial explosion has taken place. When a nuclear bomb is used there would be nuclear radiation that would still be present where the bomb hit for quite a while
What is the damage a nuclear bomb will do to you?
A nuclear bomb can cause immediate death and severe injuries from the blast, heat, and radiation. Survivors may experience radiation sickness, burns, and long-term health effects such as cancer. The extent of damage depends on the bomb's size, proximity, and other factors.
How does a nuclear bomb kill someone?
A nuclear bomb kills by releasing an intense burst of heat, light, and radiation that causes widespread damage to the surrounding area. The immediate effects include burns, blast injuries, and radiation exposure, while the long-term effects may include radiation sickness and increased risk of cancer due to exposure to radioactive fallout.
Where does the energy go after a nuclear bomb goes off?
After a nuclear bomb goes off, the energy goes into everything around the place of detonation in a variety of different forms (e.g. blast wave, flying debris, light, nuclear radiation, sound, winds).
What radiation is given off by a nuclear bomb?
prompt (at time of explosion) - neutron, gamma, x-ray, UV, visible, thermal (IR), some radio.delayed (fallout) - beta, gamma, some alpha.Types of radiation called "ionizing radiation" - alpha, beta, gamma, x-ray, neutron.
What would a nuclear bomb do?
It destroys everything in its vicinity on a cellular level, and anyone or anything that hasn't been evaporated is exposed to extreme radiation, which can lead to mutation, birth defects, or even cause serious illnesses such as cancer.
