Does Fallout's "Rule of Thumb" Work?

TL;DR

The iconic Vault Boy thumbs up pose in the Fallout games is believed to be a rule of thumb to determine safe distance from a nuclear blast, but it is actually inaccurate and useless.

long before I was a noted nuclear zatti I was a Fallout fan I have hundreds of hours in each game I've even gone as far as to work directly with Bethesda to science everything from mini nukes to Giant laser beams one thing that I was never able to science though until now is this iconic image no this isn't just Vault boy if the internet is to be be...

Key Insights

• 🔫 Nuclear weapons pose existential threats to civilization due to their complex energy distribution during a blast.
• 🫰 The Vault Boy thumbs up pose in Fallout games is believed to be a rule of thumb for safe distance from a blast.
• 😚 The dangers of being too close to a blast include radiation, thermal effects, and blast wave.
• 🫰 The thumb rule overlooks important factors and is inaccurate in determining safe distance.
• 👋 Different energies of a nuclear blast, such as radiation, blast wave, and thermal radiation, travel different distances.
• 🧡 Thermal radiation travels the furthest, followed by the blast wave, while radiation has the shortest range.
• 🦺 Nuk Map by Alex Wellerstein can be used to simulate nuclear blasts and determine safe distances.

Questions & Answers

Q: Is the Vault Boy thumbs up pose in Fallout games actually a rule of thumb for determining safe distance from a nuclear blast?

No, the thumb rule is inaccurate because it doesn't consider various factors and only focuses on nuclear fallout.

Q: What are the dangers of being too close to a nuclear blast?

Being too close to a nuclear blast can result in acute radiation poisoning, thermal burns, blindness, blunt force trauma, and soft tissue ruptures.

Q: Which aspect of a nuclear blast travels the furthest?

Thermal radiation travels the furthest after a nuclear detonation, followed by the blast wave, while radiation has the shortest range.

Q: How can visual angles and the size of the mushroom cloud be used to determine safe distance?

By comparing the visual angle of the mushroom cloud to the visual angle of an outstretched thumb, it can be determined if one is too close to a nuclear blast. However, this method is flawed and unreliable.

Summary & Key Takeaways

• The Vault Boy thumbs up pose in Fallout games is believed to indicate a safe distance from a nuclear blast.

• However, being too close to a nuclear blast involves risks from radiation, thermal effects, and blast wave.

• The thumb rule is inaccurate because it doesn't consider factors like wind speed, direction, and height of burst.
