Measure Levels of Radiation Continuously

• During the response to a radiation incident, measurement of radiation in the environment will
  • Begin as soon as possible
  • Continue throughout the response and recovery
• This information will be used by incident managers to
  • Manage the response
  • Protect responders and the public
• Various kinds of devices will be used to measure radiation in the environment, depending on the nature of the incident
  • Illustrations of selected radiation survey monitors
  • Many other kinds exist
  • Radiation levels in wide areas can also be measured by aerial surveillance
• When measurements of radiation levels are made over the incident site, maps reflecting radiation levels at a particular location and time will be created and used by incident managers.
• Computers are also used to
  • Estimate the location and amount of radiation associated with incidents of various kinds
  • Create maps used by incident managers
• Radiation levels in the environment will change over time, as radioactivity decays.
