KCARE was commissioned by the Department of Health to conduct a survey of doses from CR systems. Measurements were made by KCARE and King's Radiation Protection Service and further data collected by survey from across the UK. The analysis was carried out by KCARE and King's Radiation Protection Service. Below is a summary of the main conclusions:

• A wide range of effective doses, detector air kerma values and techniques were found for two frequently performed X-ray examinations (chest PA and abdomen AP).
• No significant difference was found in dose between CR suppliers or technique (kVp) used.
• The variation in doses observed suggests that many systems may not be optimised, or may be optimised to substantially different standards.

KCARE would like to thank all those who contributed data or provided access to equipment for this project.
