radiation dose from CT scans

Computed tomography (CT) scans are being used more frequently in clinical examinations with growing concerns over the radiation dose given to patients. Medical X-rays (including CT scans) are the largest single artificial source of radiation exposure for the UK population. Current features and developing technology allow CT to be a very versatile imaging technique for diagnosis, resulting in more extensive use of CT scans in benign disease and in younger patients. Children are one of the specific groups are known to be at greater risk from radiation exposure.

The Committee on Medical Aspects of Radiation in the Environment (COMARE) published its report investigating the impact of the increased use of CT scans in the UK. COMARE is a Department of Health Expert Committee providing independent advice to all government departments and agencies.

This press briefing was held to find out:

  • What are the CT radiation dose issues for the UK?
  • Is dose reduction achievable?
  • How can the number of CT scans be kept to a minimum?



Prof Alex Elliott, Chairman of the Committee on Medical Aspects of Radiation in the Environment (COMARE)
