A RDD combines a conventional explosive device, such as a bomb, with radioactive material and is designed to scatter dangerous and sub-lethal amounts of radioactive material over a general area. RDDs appeal to terrorists because they require limited technical knowledge to build and deploy compared to a nuclear device.
Also, the radioactive materials in RDDs are widely used in medicine, agriculture, industry, and research, and are easier to obtain than weapons grade uranium or plutonium. The size of the affected area and the level of destruction caused by an RDD would depend on the sophistication and size of the conventional bomb, the type of radioactive material used, the quality and quantity of the radioactive material, and the local meteorological conditions—primarily wind and precipitation. The area affected could be placed off-limits to the public for several months during cleanup efforts.
There is no way of knowing how much warning time there will be before an attack by terrorists using a Radiological Dispersion Device (RDD), so being prepared in advance and knowing what to do and when is important. Find out from officials if any public buildings in your community have been designated as fallout shelters. If you live in an apartment building or high-rise, talk to the manager about the safest place in the building for sheltering and about providing for building occupants until it is safe to go out.
During periods of increased threat increase your disaster supplies to be adequate for up to two weeks. Taking shelter during an radiological dispersion device or RDD event is absolutely necessary. Blast shelters are specifically constructed to offer some protection against blast pressure, initial radiation, heat, and fire. While the explosive blast will be immediately obvious, the presence of radiation will not be known until trained personnel with specialized equipment are on the scene. As you seek shelter from any location (indoors or outdoors) and there is visual dust or other contaminants in the air, breathe though the cloth of your shirt or coat to limit your exposure. If you manage to avoid breathing radioactive dust, your proximity to the radioactive particles may still result in some radiation exposure. If the explosion or radiological release occurs inside, get out immediately and seek safe shelter. If appropriate shelter is not available, move as rapidly as is safe upwind and away from the location of the explosive blast.
If you have time, turn off ventilation and heating systems, close windows, vents, fireplace dampers, exhaust fans, and clothes dryer vents.
Seek shelter immediately, preferably underground or in an interior room of a building, placing as much distance and dense shielding as possible between you and the outdoors where the radioactive material may be.
Seal windows and external doors that do not fit snugly with duct tape to reduce infiltration of radioactive particles. Terrorist use of an Radiological Dispersion Device (RDD) — often called “dirty nuke” or “dirty bomb” — is considered far more likely than use of a nuclear explosive device.
Add plastic sheeting, duct tape, and scissors to your disaster supplies kit if not already present. While the explosive blast will be immediately obvious, the presence of radiation will not be known until trained personnel with specialized equipment are on the scene.
Breathe through the cloth of your shirt or coat to help filter out dust or other contaminants in the air.


An interior room on the lowermost level, preferably without windows such as a basement, is the ideal location to stay. Potassium iodide will only protect you against inhaled or swallowed radioactive isotopes of iodine.[5] It's better to keep them for situations in which their usage becomes truly urgent. Use a plastic bag to seal and dispose of any clothing you were wearing at the time of the blast.
Continue listening to your radio or watch the television for instructions from local officials, whether you have evacuated or sheltered-in-place. The primary purpose of terrorist use of an RDD is to cause psychological fear and economic disruption. Contamination from an RDD event could affect a wide area, depending on the amount of conventional explosives used, the quantity and type of radioactive material released, and meteorological conditions.
Radiological Emission Devices (RED) are another scenario that government officials are considering.
Nuclear incidents are in a classification which includes blasts, detonations, and explosions involving a nuclear explosion with fission such as what we saw at Fukushima. To the greatest extent possible, the information has been kept simple and concise, and references for additional information have been provided. The primary purpose of terrorist use of an RDD is to cause psychological fear and economic disruption. Depending on the speed at which the area of the RDD detonation was evacuated or how successful people were at sheltering-in-place, the number of deaths and injuries from an RDD might not be substantially greater than from a conventional bomb explosion. If none have been designated, make your own list of potential shelters near your home, workplace, and school. They can be any protected space, provided that the walls and roof are thick and dense enough to absorb the radiation given off by fallout particles. Retrieve your disaster survivor supplies kit and a battery-powered radio and take them to your shelter room. Plastic sheeting will not provide shielding from radioactivity nor from blast effects of a nearby explosion. A "dirty bomb" combines a conventional explosive device — such as a bomb — with radioactive material. There is no way of knowing how much warning time there will be before an attack by terrorists using an RDD, so being prepared in advance and knowing what to do and when is important. Stock up on non-perishable goods such as rice, beans, dried fruits and vegetables, and powdered milk.
Aim to store a first aid kit, a first aid instruction booklet, as well as any emergency prescriptions in a safe place. These items are extremely versatile and will allow you to improve upon, fashion, or repair a large number of items you may need or come across after the RDD event. The size of the affected area and the level of destruction caused by an RDD would depend on the sophistication and size of the conventional bomb, the type of radioactive material used, the quality and quantity of the radioactive material, and the local meteorological conditions—primarily wind and precipitation. Particularly in an urban setting or near other likely terrorist targets, this assumption helps keep you prepared and on your toes. If you manage to avoid breathing radioactive dust, your proximity to the radioactive particles may still result in some radiation exposure.


Plastic sheeting will not provide shielding from radioactivity nor from blast effects of a nearby explosion, but can help keep radioactive dust from infiltrating your shelter. Turn on your radio, surf the web, or interact with members of your family or community in order to gain relevant, accurate information.
Terrorists using a dirty bomb likely expect widespread panic and social upheaval after a sudden strike. Although potassium iodide pills may be effectively taken in the case of nuclear bombs or nuclear power plant leaks, they are not effective against dirty bombs.[4] In the event of a dirty bomb, move away from the location of the blast as quickly as possible to limit exposure to radiation.
To do this, remove and bag your clothing (and isolate the bag away from you and others), and shower thoroughly with soap and water. Seal up any clothing that may have been contaminated, label it as radioactive, and put it somewhere far away from humans and animals. Thus, radiation dissipation rates vary, but radiation from an RDD will likely take longer to dissipate due to a potentially larger localized concentration of radioactive material. However, it will not decontaminate you from other internally ingested or inhaled radioactive elements.

It is designed to scatter dangerous and sub-lethal amounts of radioactive material over a general area. Understanding how the different variables affect the size and magnitude of the fallout area will greatly increase your chances of healthy survival. This will not safeguard you against all forms of radiation; it will merely limit your exposure. If appropriate shelter is not available, move as rapidly as is safe upwind and away from the location of the explosive blast.
Reacting calmly, logically, and decisively — as well as spreading that message of reason — is a great asset in a time of panic. Depending on the speed at which the area of the RDD detonation was evacuated or how successful people were at sheltering-in-place, the number of deaths and injuries from an RDD might not be substantially greater than from a conventional bomb explosion. If taken, it should be consumed in proper quantity and only within the first six hours of exposure. Arming yourself, and others, with the proper safety protocols can drastically reduce the likelihood of severe bodily harm.
Retrieve your disaster supplies kit and a battery-powered radio and take them to your shelter room, preferably underground or in an interior room of a building, placing as much distance and dense shielding as possible between you and the outdoors where the radioactive material may be.
