Radiological Accidents

A radiological accident involves the release of potentially dangerous radioactive materials into the environment, usually in the form of a cloud or plume.  This is considered a type of hazardous materials incident, so many of the responses are similar.


What is the best protection?

 Protection from radiation comes in 3 forms:

  • Distance - The farther you are from the source, the better.
  • Time - Over time radiation loses its intensity. The less time you are exposed the better.
  • Shielding - Using a wall or heavy material material like lead helps absorb radiation.


What will the City do? 

  • A City-wide, official announcement will be made with information and instructions.
  • The Stockton Fire Department Hazardous Materials Team and the Stockton Police Department will respond to stop the spread of the hazardous materials and provide first aid to any victims.


What should you do? 

  • Radio and TV stations will notify you if a radiological incident occurs. Stay tuned for information and instructions.
  • You may be required to evacuate or shelter-in-place. Be familiar with the procedure as outlined in the Hazardous Materials recommendations.
