Body Monitoring Services

The body monitoring service at the Public Health England Centre for Radiation, Chemical and Environmental Hazards (PHE CRCE) has a range of systems to measure radionuclides within the body using detectors positioned outside the body. Radionuclides may enter the body by inhalation, ingestion or contamination of a wound.

PHE systems are suitable for measurement of radionuclides which emit low energy as well as higher energy photons (for example, americium-241, caesium-137, or cobalt-60).

Types of monitoring offered include the following.

  • Standard whole body monitoring following a suspected intake of a radioactive substance.
  • Before and after whole body monitoring, for instances where there is a known potential for exposure. The before measurement acts as a baseline against which the after measurement can be compared.
  • Specific organ monitoring, eg lungs or liver.
  • Bespoke wound monitoring.
