Nuclear fallout comprises radioactive debris generated by a nuclear explosion, which can impact areas far beyond the blast zone. In the event of a radiation emergency, prioritize seeking indoor shelter promptly. Ideally, find refuge in the basement of a sturdy brick or concrete structure. Remain calm, tune in to your local emergency broadcast channel, and adhere to all directives issued by authorities. Unless instructed otherwise, remain indoors until authorities deem it safe to venture outside.
Procedures
Immediate Response to the Blast
Take cover, lie flat, and shield yourself if you're close to the blast. Seek refuge behind any available protection, lie face down, close your eyes, and shield your head and face with your hands. Avoid looking directly at or facing the explosion's flash if in proximity to the blast site.
- If in a vehicle, pull over, stop, duck down, and protect your head and face.
Use a cloth to cover your nose and mouth when outdoors. If you lack a clean cloth, utilize the inner part of your undershirt. Maintain coverage until you reach an indoor shelter.
- Masking your nose and mouth reduces the intake of radioactive particles.
Escape if you spot a visible cloud of debris heading your way. When dust or debris approaches, evacuate perpendicular to its trajectory. For example, if the cloud approaches from the north, move east or west.
Safety advice: Evacuate only in the presence of an evident debris cloud or upon directive from authorities. If you're not in close proximity to the blast, seek refuge indoors. Structures, particularly those made of brick or concrete, can shield against harmful radiation effectively.
Seek shelter in a brick or concrete building if no visible debris cloud is present. Stay indoors if evacuation isn't advised. Head to the basement of a sturdy brick or concrete structure if possible. If wind direction is known, take cover on the opposite side, away from windows and doors.
- For instance, if prevailing winds blow northwest to southeast, seek refuge in the southeast corner.
- Locate the nearest brick or concrete building within 10 minutes. If none are available, find shelter in a basement-equipped structure. If that's not feasible, seek refuge in an interior room devoid of windows.
Taking Shelter Indoors
Disable ventilation systems and seal doors and windows using duct tape. Turn off heating or air conditioning systems to reduce contamination. Close and lock all doors and windows, and shut fireplace dampers if present. If time permits and duct tape is available, use it to seal cracks around doors and windows.
- Sealing the building can minimize exposure to radioactive fallout.
- Depending on your proximity to the blast, you may have 10 minutes or more to seek shelter and seal the building. If you have a battery-powered or hand-cranked radio, follow local authorities' instructions for sheltering in place.
Strip off outer clothing and store in sealed bags. Remove outer garments carefully to avoid spreading radioactive material. Place them in tightly sealed bags or containers and store away from people, pets, and packaged food and water.
- Isolating outer layers of clothing can remove up to 90% of radioactive contamination.
Cleanse your body with a shower or gentle soap and warm water. Rinse off with warm water if a shower is accessible, gently washing with soap. Otherwise, use any available water source. Additionally, wipe eyelids, eyelashes, and ears, and blow your nose to remove radioactive residue.
- Avoid vigorous scrubbing to prevent radioactive particles from entering your body through damaged skin. Cover open wounds with bandages before washing to prevent particle entry.
- Tap water isn't suitable for drinking but can be used for decontamination. Radioactive material in tap water is diluted, making it safe for bathing.
- Shampoo your hair without conditioner, as conditioner may trap radioactive particles on your hair and body.
Decontaminate your pets: If pets were potentially exposed to radiation outdoors, wash them with warm water and soap. When decontaminating pets or others, wear gloves and cover your face with a mask, cloth, or towel if possible.
Consume only packaged food and bottled water. Avoid tap water and unpackaged outdoor food during a radiation emergency. Consume only packaged items stored indoors and store food and water in shielded containers. Despite power outages, refrigeration can help shield food and water from radiation.
- Wash hands with soap and warm water before eating and drinking.
- Keep a 3-day emergency supply of non-perishable food and water on hand at all times for disaster preparedness.
Remain indoors until authorities declare it safe to venture outside. Radiation levels are most intense immediately after a nuclear explosion. After approximately 8 hours, radiation levels drop significantly; stay in the basement or an interior, windowless room during this time. You may need to stay indoors for at least 24 to 48 hours.
- Do not exit until given clearance by authorities. Listen for instructions on your battery-powered or hand-cranked radio, if available. If not, seek emergency information from another electronic device. Emergency responders may enter buildings to search for survivors once deemed safe.
Manage waste securely if public services are unavailable. With prolonged sheltering, waste disposal becomes crucial. Wrap food remnants in plastic or foil, then place in sealed containers. In the absence of functioning toilets and if unable to leave home, create a latrine using a bucket lined with a sturdy plastic bag.
- Seal the bag tightly after use and dispose in a securely sealed trash receptacle, lined with a heavy-duty plastic bag. Keep waste away from food, water, and living areas. Disinfect hands with rubbing alcohol and sanitize surfaces with diluted bleach solution.
Contact emergency services if critical medication is depleted. Reach out if vital medication like insulin is needed, or for urgent medical assistance. If unable to contact emergency services, seek aid from neighbors or locate necessary medication nearby.
- Cover your face, wear protective clothing, and decontaminate after seeking assistance. If necessary, head to the nearest medical facility, maintaining caution while driving.
Ensuring Safety During a Radiation Crisis
Stay informed through radio, TV, or other media sources. Tune in to emergency broadcasts for evacuation notices, recommended routes, and other guidance. If unable to access emergency alerts, remain indoors until responders arrive.
- Follow evacuation instructions, listen for shelter locations, or text “SHELTER” and your zip code to 43362 if cell service is available in the U.S.
- Prioritize knowing designated disaster shelters in your area. Invest in a battery-powered or hand-cranked radio for updates in case of power outages.
Prepare an emergency supply kit beforehand. If you lack an emergency kit, gather flashlights, spare batteries, non-perishable food, and bottled water. Also include medications, eyewear, cash, and pet supplies. When evacuating to a public shelter, bring these essentials along with important documents like passports and banking details.
Essential emergency items: Ensure a first aid kit, a battery-powered flashlight, phone chargers, and an emergency radio. Remember a manual can opener and extra batteries. Pack sturdy footwear, spare clothes, and a warm blanket.
Avoid hazards like debris and fallen power lines during evacuation. Adhere to designated evacuation routes provided by local authorities. Avoid shortcuts that may be obstructed. Steer clear of unstable structures, watch for road damage, and avoid approaching live power lines.
- While driving, keep windows closed to minimize radiation exposure. Close vents and refrain from using the air conditioner or heater.
Keep in touch with loved ones if feasible. Initially, keep phone lines clear for emergency calls. Cell service may be limited. Once in shelter, contact family if possible and if authorities permit.
- For urgent communication, send texts or emails instead of making calls. Only return to the affected area after authorities give clearance.
Recommendations
-
The specific actions to take vary based on the scale and type of radiation emergency. If feasible, tune in to your local emergency channel and adhere to instructions from authorities.
-
A battery-powered or hand-cranked National Oceanic and Atmospheric Administration (NOAA) weather radio is among the most reliable methods to stay informed during a catastrophe.
Caution
- Do not ingest potassium iodide or any other medication for radiation exposure treatment without consulting a medical professional.
