🚨 What to do RIGHT NOW
📍 Less than 1 hour after blast
❌ Do NOT go outside under any circumstances. Stay deep inside your shelter.
📍 1–6 hours after explosion
If you are in a poor shelter, move to a safer place: basement, subway, or the core of a concrete building — only if relocation takes less than a few minutes. Close windows and seal ventilation.
📍 6–24 hours
Brief external assessment possible, but do NOT leave shelter for extended periods.
📍 1–2 days
Short outings only if necessary, with protection (full clothing, mask, gloves).
📍 After 2 days
Risk drops significantly. Venturing outside becomes safer, but caution remains essential.
⚠ Golden rule of survival
The less time since detonation → the more critical it is to stay inside.
The first hours deliver the highest radiation dose. Every hour indoors dramatically reduces risk.
🧭 Essential survival tips
📦 Prepping supplies in advance
Water (2–3 liters per person/day), canned food, flashlight, batteries, first-aid kit, battery-powered radio, N95 masks, warm clothing and blankets.
🏠 Best shelter options
Basement or center of a concrete building without windows. The more wall layers between you and the outside, the better your protection.
🚪 First hours behavior
Stay put. Shut ventilation, windows and doors. Listen to emergency radio and official alerts.
☢ Radiation shielding
Maximize distance from fallout, use dense materials (concrete, earth, brick) as protective barriers.
🚶 If you MUST go out
Minimize time outdoors, cover all skin, wear mask & hood. After returning, remove outer clothing carefully and wash exposed skin.
📡 Reliable information
Rely on official sources only. Ignore rumors and social media speculation.
⚠ Core survival principle
Shelter + Time + Minimal movement = increased chance of survival.
🛡 Best protection levels
🏠 Basement (underground)
Excellent protection against gamma radiation.
🏢 Concrete building core
Very high protection (especially multi-story).
🧱 Brick house
Moderate protection; stay away from windows.
🏡 Wooden house
Low protection – seek better shelter asap.
🚗 Vehicle / Car
Very low protection (only for immediate evacuation).
⛺ Tent / Light structure
Negligible protection – deadly in fallout zone.
☢ The 3 fundamental rules
⏱ Time
Spend as little time outdoors as possible. Reduce exposure duration.
📏 Distance
Maximize distance from ground zero and contaminated areas. If you must go out, keep distance + minimize time.
🧱 Shielding
Use dense barriers: concrete, bricks, earth, or thick metal between you and fallout.
