Radiation protection is a broad area within medical physics and radiology. This multi-authored text covers the breadth of the field. The contents are divided into four parts leading from the theoretical background needed for the use of ionising radiations in medicine. The first part covers the key knowledge needed to understand radiation protection. The second part takes a practically-orientated approach to the principles, techniques and legislation in the field. The third and fourth parts cover solutions for radiation protection for firstly ionising radiation, and the non-ionising radiation, an area which is often neglected in other texts.
