For those who don’t know:

The radioactive radius of a nuclear bomb, depending on the bomb's yield, can range from a few hundred meters for a small bomb to several kilometers for a large one, with the most dangerous radiation exposure occurring within the first few miles downwind from the blast due to radioactive fallout; however, the exact distance depends heavily on weather conditions and the terrain.

Key points about radioactive radius:

Immediate radiation:

The most intense radiation is experienced very close to the explosion site, within a relatively small radius, causing immediate radiation sickness to exposed individuals.

Fallout:

The major concern for long-term radiation exposure is the radioactive fallout, which can spread much further depending on wind patterns and can contaminate large areas downwind from the blast.

Yield matters:

A larger nuclear bomb will have a larger radioactive radius compared to a smaller one.

Edit:


The size of a nuclear bomb directly impacts the amount of fallout produced, as a larger bomb generates a more powerful explosion, propelling a larger quantity of radioactive material higher into the atmosphere, leading to a wider dispersal of fallout over a larger area when it eventually falls back to the ground; essentially, the bigger the bomb, the more potential fallout there is to spread.

Key points about how bomb size affects fallout:

Larger fireball:

A larger bomb creates a bigger fireball which draws in more debris from the surrounding environment, increasing the amount of material that becomes radioactive and can be dispersed as fallout.

Higher altitude reach:

A bigger explosion propels radioactive particles to higher altitudes, allowing them to travel further with prevailing winds before settling as fallout.

Increased particle size variation:

Larger bombs can produce a wider range of particle sizes in the fallout cloud, with some particles remaining airborne for longer periods, further extending the potential fallout zone.

Factors influencing fallout beyond bomb size:

Detonation height:

Exploding a bomb at a higher altitude can minimize local fallout but potentially spread radioactive material over a larger area due to wind patterns.

Weather conditions:

Wind direction and precipitation can significantly affect the distribution of fallout after a nuclear explosion.

Terrain:

The type of terrain where the bomb detonates can influence how much material is picked up and becomes part of the fallout.
