How to Stay Safe in a Nuclear Explosion

🏢Getting inside a sturdy building is the best way to protect yourself from a nuclear explosion's blast, shockwave, heat, and radiation.

🌬️Thick layers of steel, concrete, and packed earth can provide serious protection against radioactive fallout.

🌡️Stay inside for 24 hours after a nuclear detonation to improve the chances of avoiding the most serious effects of radiation.

📻Listen to emergency responders on radios to determine the safest course of action.

🌍Studies and simulations have shown the benefits of following the scientifically supported protocols for protection in the event of a nuclear explosion.

How can I protect myself from a nuclear explosion?

—The best way to protect yourself from a nuclear explosion is to get inside a sturdy building, preferably with thick layers of steel, concrete, and packed earth. Stay inside for at least 24 hours to minimize exposure to radiation.

What should I do if I get caught in the fallout?

—If you get caught in the fallout, find a safe space, remove your shoes and outer layers, wash any exposed skin, and store contaminated clothing far away. Stay inside for at least 24 hours and seek outside help only if necessary.

How long does it take for the most hazardous fallout to occur?

—The most hazardous fallout occurs in the first hour after a nuclear detonation. It gives off half of its energy within the first hour and 80% within the first day.

What if I don't have access to electricity, cell service, or the internet?

—In the event of a nuclear detonation, most radios would likely survive and can be used to listen to emergency responders for updates and instructions.

Why should I trust these protective measures?

—These protective measures have been studied and simulated repeatedly and have shown to be effective in minimizing the risks and negative effects of a nuclear detonation.
