Radiological and nuclear emergencies

A radiological or nuclear emergency is an event that has led, or could lead, to a radiological threat to public health and safety, property, or the environment.

The likelihood of a nuclear or radiological incident is remote because of the stringent controls in place for the movement and use of radioactive materials. A radiological or nuclear emergency may occur if there's an accident in a nuclear facility or during transportation of radioactive materials. It can also come from a device that spreads radiation, a device that exposes people to radiation, or a nuclear weapon explosion.

All levels of government, and radiological and nuclear facilities, have emergency plans that may be quickly put into action if required. In a radiological or nuclear emergency, whatever the cause, fast action is required to reduce the threat.

Why prepare for radiological and nuclear emergencies

In the event of an emergency, officials will quickly determine the degree of risk and take fast measures to limit the dangers to people and the environment. Depending on how serious the incident is, your closeness to the event, and any potential health risks, local authorities may issue different instructions. You should be prepared to shelter-in-place or to evacuate.
