how far can nuclear bomb radiation travel

The distance that nuclear bomb radiation can travel depends on several factors, including:

1. Type and size of the bomb: Larger bombs produce more radiation, which can travel farther.
2. Altitude of the explosion: Explosions at higher altitudes can spread radiation over a wider area.
3. Weather conditions: Wind, rain, and other weather factors can affect the dispersal of radiation.
4. Type of radiation: Different types of radiation (e.g., alpha, beta, gamma) have varying ranges and penetration capabilities.

Here are some general guidelines on the distances that nuclear bomb radiation can travel:

Immediate Blast Zone (0-1 km / 0-0.6 miles):

• Within this zone, the radiation is extremely high, and the risk of acute radiation syndrome (ARS) is very high.
• Radiation levels can be lethal, with doses exceeding 10 Gy (1,000 rads).

Near Zone (1-10 km / 0.6-6.2 miles):

• Radiation levels decrease with distance, but are still high enough to cause significant harm.
• Doses can range from 1-10 Gy (100-1,000 rads), which can cause severe radiation sickness.

Far Zone (10-50 km / 6.2-31 miles):

• Radiation levels continue to decrease, but can still pose a significant risk to people and the environment.
• Doses can range from 0.1-1 Gy (10-100 rads), which can cause mild to moderate radiation sickness.

Distant Zone (50-100 km / 31-62 miles):

• Radiation levels are relatively low, but can still be detectable.
• Doses are typically below 0.1 Gy (10 rads), which is considered a relatively low risk.

Global Dispersion:

• Radioactive particles can be carried by winds and dispersed globally, contaminating the environment and potentially affecting people far from the blast site.
• This phenomenon is known as "global fallout."

Some examples of nuclear bomb radiation travel distances:

• The Trinity test (1945): Radiation was detected 160 km (100 miles) away from the blast site.
• The Chernobyl disaster (1986): Radioactive particles were detected in Scandinavia, over 1,000 km (620 miles) away.
• The Fukushima Daiichi nuclear disaster (2011): Radioactive particles were detected in the United States, over 8,000 km (5,000 miles) away.

Keep in mind that these distances are approximate and can vary greatly depending on the specific circumstances of the nuclear event.
