Eric Hall and Amato J. Giaccia: Radiobiology for the radiologist, 6th edn. | SpringerLinkIonizing radiation in the form of X-rays is used for the majority of procedures in interventional radiology. This review article aimed at promoting safer use of this tool through a better understanding of radiation dose and radiation effects, and by providing guidance for setting up a quality assurance program. To this end, the authors describe different radiation descriptive quantities and their individual strengths and challenges, as well as the biologic effects of ionizing radiation, including patient-related effects such as tissue reactions previously known as deterministic effects and stochastic effects. In this article, the clinical presentation, immediate management, and clinical follow-up of these injuries are also discussed. Tissue reactions are important primarily from the patients' perspective, whereas stochastic effects are most relevant for pediatric patients and from an occupational viewpoint. The factors affecting the likelihood of skin reaction the most common tissue reaction are described, and how this condition should be managed is discussed.

This trend has been hypothesised to reflect a combination of technological advances enabling increased detection, but also changes in environmental factors, including population exposure to ionising radiation from fallout, diagnostic tests and treatment for benign and malignant conditions.

The Oxygen Enhancement Ratio OER or oxygen enhancement effect in radiobiology refers to the enhancement of therapeutic or detrimental effect of ionizing radiation due to the presence of oxygen. This so-called oxygen effect  is most notable when cells are exposed to an ionizing radiation dose. The OER is traditionally defined as the ratio of radiation doses during lack of oxygen compared to no lack of oxygen for the same biological effect. This may give varying numerical values depending on the chosen biological effect. The value of the maximum OER varies from about The effect is used in medical physics to increase the effect of radiation therapy in oncology treatments. Additional oxygen abundance creates additional free radicals and increases the damage to the target tissue.
To browse Academia., This book is an important source of information for everybody wishing to improve their knowledge in the field of ionising radiation and, in particular, radiobiology. The book is particularly welcome given the limited number of up-to-date books on this topic, which is considered ancillary in an area dominated by publications related to technical and clinical aspects.
