That is complicated:

  • Depends on yield and height/depth of burst.
  • Depends on several features of bomb design.
  • Depends on halflives of radiological contaminants produced.
  • Depends on decontamination effort attempted and degree of success.
  • Depends on weather.

The aftermath of a nuclear bomb explosion can last for years, depending on the size of the bomb and the radiation released. The immediate blast impact and thermal effects would be over in seconds to minutes, but the long-term effects, such as radiation contamination and environmental damage, could persist for decades. Recovery and cleanup efforts would take a significant amount of time and resources.

How powerful is a nuclear bomb?

Nuclear bombs are extremely powerful weapons that can unleash immense destruction by releasing energy equivalent to thousands or even millions of tons of TNT. The destructive power of a nuclear bomb is measured in terms of its explosive yield, which can range from a few kilotons to multiple megatons. The effects of a nuclear bomb blast can include devastating immediate destruction, intense heat, radiation, and long-lasting environmental impacts.


What would happen if a nuclear bomb hit?

If a nuclear bomb hit, it would cause catastrophic damage and death to the surrounding area. The bomb sends out a fire ball that destroys buildings and everything in its pathway. It also sends out radiation in the form of gamma rays that is harmful to everything around it. It is unsure the exact damage, because each individual could be exposed to different amounts.


How do you protect yourself from a nuclear bomb?

To protect yourself from a nuclear bomb, seek shelter in a sturdy building or basement, ideally underground, to reduce exposure to radiation. Stay inside and close windows and doors to minimize dust and debris entering the building. Follow emergency instructions from authorities and have an emergency kit prepared with supplies like water, food, and first aid items.


How long would it take to produce nuclear power?

It can take up to 10 years to build a new nuclear power plant, from initial planning to completion. Factors such as regulatory approvals, site selection, and construction can all affect the timeline.


How much power do an average nuclear weapon have?

An average nuclear weapon can have explosive power ranging from tens of kilotons to hundreds of kilotons of TNT equivalent. For comparison, the bomb dropped on Hiroshima in 1945 had an explosive power of around 15 kilotons.
