Trainees in oncology learn about ionising radiation, but to understand it fully they must also understand the physics relevant to its use in therapy. This is the first book written specifically for the oncology and radiation team. It begins with basic concepts and then explores the principles and practice of physics as it relates to radiotherapy, including discussion of specific types of therapy. ABOUT THE SERIES: Radiotherapy remains the major non-surgical treatment modality for the management of malignant disease. It is based on the application of the principles of applied physics, radiobiology, and tumour biology to clinical practice. Each volume in this series takes the reader through the basic principles of the use of ionising radiation and then develops this by individual sites. This series of practical handbooks are aimed at physicians both training and practising in radiotherapy, as well as medical physicists, dosimetrists, radiographers and senior nurses.
