Nuclear and Radiological Emergencies (2024)

A nuclear or radiological emergency might be an accident at a nuclear power plant, the use of a small nuclear weapon or someone setting off a “dirty bomb.” When a dirty bomb explodes, it sends off dangerous radioactive material over a certain area. Radiation's health effects can be mild, like reddening of the skin, or very serious, like cancer or even death.

Nuclear and Radiological Emergencies (1)

BEFORE A NUCLEAR OR RADIOLOGICAL EMERGENCY HAPPENS:

  • Be sure you have your emergency supply kit ready.Nuclear and Radiological Emergencies (2)

  • Make sure you know where and how to get information from your city or town.

  • If you live within 10 miles of a nuclear power plant, you should know the evacuation routes for your neighborhood.

WHEN A NUCLEAR OR RADIOLOGICAL EMERGENCY HAPPENS:

  • During and after a release of radioactive materials, local, state and federal authorities will watch the levels of radiation and tell you what you should do to protect yourself.

  • The best action will depend on the emergency. Tune to your local TV, radio stations and Internet for information and instructions during any emergency.

  • If a lot of radioactive material is released in a radiological emergency, you may be told to "shelter in place," which means to stay indoors where you are; or you may be told to move to another location.

If you are told to shelter in place, you should do the following:

  • Close and lock all doors and windows.

  • Turn off fans, air conditioners, and forced-air heating units that bring in fresh air from the outside. Only use units that recirculate air that is already in the building.

  • Close fireplace dampers.

  • If you can, bring pets inside.

  • Move to an inner room or basem*nt.

  • You may also consider sealing the room (see Sealing the Room, below)

  • Keep your radio tuned to the emergency response network or local news to find out what else you need to do.

  • Do not leave your shelter until you are told that it is safe by local officials.

  • If you are told to evacuate, follow the directions from your local officials. Leave the area as quickly and orderly as possible. Also:

    • Turn off the fan, air condition, and heating system in your car. These bring in air from the outside. Close your vents and keep your windows rolled up.

    • Take your emergency supply kit, medicines you need, extra clothes, cash and credit cards.

    • Take pets only if you are using your own vehicle and going to a place you know will accept animals. Emergency vehicles and shelters usually will only accept service animals and may not accept pets.

AFTER A NUCLEAR OR RADIOLOGICAL EMERGENCY:

  • Check your local TV and radio stations and the Internet for official news, information and instructions.

SEALING THE ROOM:Nuclear and Radiological Emergencies (6)

During a chemical, nuclear or radiological emergency, the air outside may be dangerous. For short periods of time, "sealing the room" can help protect you and your family from harmful air outside. If you see large amounts of debris in the air, or if local officials say the air is dangerous, you may want to take this kind of action.

Choose one room in the middle of your home or a room with no windows as your shelter. When you move to your shelter, use duct tape and plastic sheeting to seal any doors, windows, or vents in case a chemical or radiation plume is passing over (listen to your radio for instructions). Within two or three hours, you should take down the plastic and duct tape and air out the room. You can suffocate if you keep the room tightly sealed for more than five hours.

To seal a room:

  • Seal all windows, rooms and air vents in one room with 2-4 mil. thick plastic sheeting and duct tape. You might want to measure an duct the plastic sheeting in advance to save time.
  • Cut the plastic sheeting at least six inches wider than the openings and label each sheet.
  • Duct tape plastic at corners first and then tape down all edges.

Connecticut has special plans in case there is an emergency at the nuclear power plants at the Millstone Station in Waterford, Connecticut or Indian Point in Buchanan, New York. These plans include steps the state takes to protect the health and safety of all Connecticut residents. If an emergency happens at one of these facilities, public safety officials will begin the state emergency response plan and tell residents what is going on and what to do.

emergencies involve release of the energy resulting from a nuclear chain reaction or from the decay of the products of chain reaction (e.g. nuclear power plant accidents such as Chernobyl and f*ckushima accidents). Radiological emergencies are situations involving a radiation exposure from a radioactive source.

What is the difference between radiological and nuclear hazards? ›

Nuclear incidents involve detonation of a nuclear device whereas radiological incidents produce radiation without detonation of a nuclear device.

What is an example of a nuclear emergency? ›

A nuclear power plant accident, nuclear explosion or a dirty bomb are examples of radiation emergencies. Unintentional acts, or radiation accidents, can include: Nuclear Power Plant Accident – An accident at a nuclear power plant could release radioactive material into the air or water around a nuclear power plant.

What are the different types of radiation emergencies? ›

These include:
  • Spills or releases of radioactive materials (e.g., radionuclides or radioactive isotopes) from facilities where they are used for research or medical procedures.
  • Transportation incidents involving radioactive materials.
  • Medical procedures involving radioactive materials, such as radiopharmaceuticals.

What is the difference between red and RDD? ›

An RDD is commonly known as a "dirty bomb." Radiological Exposure Device (RED) A radiation emitting item used to maliciously expose people, without dispersal of radioactive material. Radiological Poisoning Device (RPD) Radioactive material used to cause harm by malicious ingestion or injection.

What is a radiological emergency? ›

What is a Radiation Emergency? A radiation emergency is defined as any unplanned event involving nuclear materials or radiation producing devices that may result in an increased exposure of individuals to ionizing radiation.

What are examples of radiological hazard? ›

The greatest radiological hazard would be one where the uranium is in close proximity to a cell for a long period of time, such as with an inhalation exposure of an insoluble form of uranium that is small enough to pass through the pulmonary system to the alveoli.

What are the 4 levels of nuclear emergency? ›

The four emergency classification levels used for commercial nuclear power plants, in ascending order of severity, are: Notification of Unusual Event, Alert, Site Area Emergency, and General Emergency.

What is the difference between radiological and nuclear? ›

As we have established, nuclear releases involve the detonation of a radiological device, whereas radiological emergencies do not. This is why nuclear power plant operator training might involve different skill sets and decision making processes from those required for an appropriate nuclear detonation response.

How do you survive a radiation emergency? ›

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.

What to do during a nuclear emergency? ›

Go to the basem*nt or the middle of the building. Radioactive material settles on the outside of buildings; so the best thing to do is stay as far away from the walls and roof of the building as you can. If possible, turn off fans, air conditioners, and forced-air heating units that bring air in from the outside.

What blows up and spreads radiation? ›

Nuclear Emergencies

A nuclear emergency involves the explosion of a nuclear weapon or improvised nuclear device (IND). The explosion produces an intense pulse of heat, light, air pressure, and radiation. Nuclear explosions produce fallout (radioactive materials that can be carried long distances by the wind).

Is an RDD a dirty bomb? ›

A dirty bomb is a mix of explosives, such as dynamite, and radioactive powder or pellets. It is also known as a radiological dispersal device (RDD). A dirty bomb cannot create an atomic blast. When the bomb explodes, the blast carries radioactive material into the surrounding area.

Is RDD still used? ›

However, RDDs are still available and can be used when you need more control over low-level transformations and fine-grained operations. RDDs are: Immutable: RDDs are read-only, meaning you can't change their content. Once created, RDDs are immutable.

What are the two types of RDD? ›

Now, operations can be performed on the RDD. There are two types of RDD operations: transformations, which yield a new RDD, and actions, which return a value.

What is the difference between radiology and nuclear? ›

Nuclear Medicine: Reveals how well organs and tissues are functioning, offering early disease detection. Radiology: Provides detailed images of the anatomy, helping diagnose conditions based on structural appearance.

What is the difference between radiological and nuclear in CBRN? ›

Radiological: Illness caused by exposure to harmful radioactive materials. Nuclear: Life-threatening health effects caused by exposure to harmful radiation, thermal or blast effects arising from a nuclear detonation.

Are nuclear and radiological weapons the same? ›

A radiological weapon is not a nuclear weapon. Even if uranium or plu- tonium is spread by a radiological bomb, the blast effect is due only to the high explosive; no nuclear fission occurs, as it would in a nuclear bomb.

What is the difference between radiology and nuclear radiology? ›

The two fields also have differences in these key areas: Image type: Medical professionals use radiology to capture visual aspects of internal anatomy, such as size, shape and location. They use nuclear medicine to determine the function and behavior of internal organs, like chemical interactions or cell growth.
