Essential Nuclear Preparedness Guides
All guides are based on publicly available emergency preparedness information from FEMA, the CDC, and the IAEA. Updated regularly to reflect current protocols.
What To Do In A Nuclear Attack
Step-by-step survival protocol for the first minutes and hours after a nuclear detonation. Covers drop and cover, sheltering, and decontamination.
Nuclear Fallout Shelter Guide
How to identify, build, and provision a fallout shelter. Covers shielding principles, improvised shelters, and what materials provide the best protection.
How Long Does Radiation Last?
Understanding the 7:10 Rule of radiation decay — the most critical concept for knowing when it is safe to leave your shelter after a nuclear event.
Radiation Exposure Symptoms (ARS)
Recognize the three stages of Acute Radiation Sickness (ARS): the prodromal stage, the latent phase, and the manifest illness stage.
Nuclear Emergency Kit Checklist
A complete checklist of essential supplies for surviving the critical 14 days following a nuclear event. Covers water, food, communication, and medical needs.
Nuclear Survival FAQ
Answers to the most frequently asked questions about nuclear war, survival probability, which countries are safest, and what to do if WW3 breaks out.
The Three Phases of Nuclear Survival
According to FEMA's official nuclear detonation response guidance, survival depends on your actions in three distinct phases.
Before an Attack
Preparation and shelter planning. Identify fallout shelters near your home, workplace, and school. Build a 14-day emergency supply kit and establish a family communication plan.
Prepare Now →During an Attack
Immediate life-saving actions. Get inside the nearest substantial building, move to the center away from windows, and stay put. Do not look at the fireball. Decontaminate as soon as possible.
Read Protocol →After an Attack
Post-blast recovery and safety. Stay sheltered for at least 24–48 hours. Monitor emergency broadcasts. Understand the 7:10 Rule of radiation decay to know when it is safe to leave.

The Invisible Shift: Why Knowledge Is Your Only Real Shield
In April 1986, the birds kept singing and the sun kept shining — but the air had silently changed. History's most defining nuclear moments, from the technical failures at Chernobyl to the seismic triggers of Fukushima, did not start with a roar. They started with a silent shift in data.
Most people think of nuclear risks only as battlefield scenarios. The reality is different. There are over 400 active civilian reactors worldwide. A technical event or a natural disaster does not recognize borders. At Nuclear Ready, we analyze these events objectively so you can understand the patterns of the invisible.
We bridge the gap between complex CBRN science and your front door. If the wind direction changes during a localized incident, do you know how to read a radiation map? Do you know which materials in your own home actually block alpha particles versus gamma rays?
Our mission is to move you from "what if" to "I know." We provide the technical protocols and environmental insights you need to become an informed protector of your family in an increasingly complex world.
