Description
This book provides an overview of brachytherapy practice, the sources available, an insight into the associated dosimetry and a practical guide to the use of dosage systems together with consideration of safety aspects in clinical situations. It is a practical teaching text for those working and one which provides a useful starting point for readers seeking to understand clinical brachytherapy and the associated dosimetry. For medical physicists, junior registrars in departments of radiotherapy and oncology and radiotherapy radiographers. A good introduction to the subject. Contains extensive references.
