CT scanners

Hazard Knowledge

CT (computerised tomography) scanners will most commonly be found in medical facilities, such as hospitals. However, they may also be found in animal facilities, such as veterinary clinics and hospitals. Refer to the supplementary information for further detail about CT scanners.

The main hazards relating to CT scanners are:

  • Electricity - CT scanners use a three-phase, 400V electrical supply
  • Ionising X-ray radiation - the CT scanner takes many X-ray images which are then combined by computer to create a 3D image. The X-ray radiation is produced electrically and ceases to exist once power is isolated.
