The Manchester System and the BCRU recommendations for brachytherapy source specification.

The decision to endorse and implement the BCRU recommendation has been taken after careful consideration and discussion amongst those currently active in brachytherapy treatment at the Christie Hospital, Manchester. We believe it to be both logical and scientifically sound. The practical measures discussed here outline how the Manchester System will operate with the new method of source specification, and we urge other users of the Manchester System throughout the world to adopt similar measures and accept the BCRU recommendations also.
