There are different types of radiation emergencies that vary in how much damage they cause and harm they pose to the public. Some examples of radiation emergencies include: a nuclear detonation (explosion), an accident at a nuclear power plant, a transportation accident involving a shipment of radioactive materials, or an occupational exposure like in a healthcare or research setting. While the extent of the damage will vary, the steps to protect yourself from radiation are the same. You can keep your family safe by knowing what to do and being prepared if an incident occurs. Follow these simple steps:

The best way to stay safe in any radiation emergency is to get inside, stay inside and stay tuned. Putting material between you and the radiation provides protection while you tune in for instructions from responders.

HOW TO STAY SAFE IN THE EVENT OF A RADIATION EMERGENCY

Prepare NOW

Like in any emergency, you need reliable information, enough supplies and a plan to protect yourself and your family during radiation and nuclear emergencies.

Stay Safe DURING

During any radiation emergency, follow the radiation protection principles of time, distance, and shielding. Limit your time exposed to radiation, stay as far away as possible from a radioactive source, and shield yourself from radiation by going deep inside a sturdy building.

If the emergency is outside, Get inside. Stay inside. Stay tuned.

GET INSIDE: If warned of the possibility of a radiation hazard, immediately get inside the nearest building and move away from windows. Put as many walls between you and the outside to protect you from the radiation outside.

NUCLEAR DETONATIONS: Nuclear detonations are the most dangerous radiation emergency. It creates a large, deadly blast. If it detonates on the ground, the explosion can suck material up into the air and create dangerous, sand-like, radioactive particles called fallout.

For a nuclear explosion, if you have warning, take cover from the blast behind anything that might offer protection. If you are outside, lie face down to protect exposed skin from the heat and flying debris. After the shockwave passes, go inside the nearest building as quickly as possible.

GET INSIDE: After a detonation, you will have 10 minutes or more to find an adequate shelter before fallout arrives. If a multi-story building or a basement can be safely reached within a few minutes of the explosion, go there immediately. The safest buildings have brick or concrete walls. Underground parking garages and subways can also provide good shelter.

Remain in the most protective location (basement or center of a large building) for the first 24 hours unless threatened by an immediate hazard (e.g., fire, gas leak, building collapse, or serious injury) or informed by authorities that it is safe to leave.Radiation levels decrease rapidly, becoming significantly less dangerous, during the first 24 hours.

STAY INSIDE: Take shelter unless told otherwise. If possible, turn off fans, air conditioners, and forced-air heating units that bring air in from the outside. Close windows and doors. Close fireplace dampers. If you are instructed to stay inside during a radiation emergency, pets and service animals should be inside too. Sheltering usually lasts at least 24 hours.

STAY TUNED: Follow instructions from emergency response officials. If advised to evacuate, listen for information about routes, shelters, and procedures. If you have evacuated, do not return until you are told it is safe to do so by local authorities.

Be Safe AFTER

If you were outside during a radiological release or if you think you have radioactive material on your body, there are simple steps to remove it.
