Lessons Learned from Accidental Exposures in Radiotherapy


Book Description

This Safety Report is a review of a large number of events that may serve as a checklist against which to test the vulnerability of a facility to potential accidents, and to provide a basis for improving safety in the use of radiation in medical applications. Furthermore, it is intended to encourage the development of a questioning and learning attitude, the adoption of measures for the prevention of accidents, and the preparation for mitigation of the consequences of accidents, if they occur.




The Radiological Accident in Chilca


Book Description

Under the Convention on Assistance in the Case of a Nuclear or Radiological Emergency, the Peruvian authorities requested assistance from the IAEA in relation to the radiological accident that occurred during non-destructive testing using a nuclear radioactive source in the district of Chilca, Peru, in 2012. This assistance related to dose assessment and medical management of those involved in the accident was provided during 2012 and 2013. The report gives a detailed account and analysis of the event, as well as, the actions taken in order to assist organizations responsible for radiation protection, source safety and emergency preparedness and response in identifying lessons to be learned that may help to prevent similar accidents.

Radiation


Book Description

The author is ready to assert that practically none of the readers of this book will ever happen to deal with large doses of radiation. But the author, without a shadow of a doubt, claims that any readers of this book, regardless of gender, age, financial situation, type of professional activity, and habits, are actually exposed to low doses of radiation throughout their life. This book is devoted to the effect of small doses on the body. To understand the basic effects of radiation on humans, the book contains the necessary information from an atomic, molecular and nuclear physics, as well as from biochemistry and biology. Special attention is paid to the issues that are either not considered or discussed very briefly in existing literature. Examples include the ionization of inner atomic shells that play an essential role in radiological processes, and the questions of transformation of the energy of ionizing radiation in matter. The benefits of ionizing radiation to mankind is reflected in a wide range of radiation technologies used in science, industry, agriculture, culture, art, forensics, and, what is the most important application, medicine. Radiation: Fundamentals, Applications, Risks and Safety provides information on the use of radiation in modern life, its usefulness and indispensability. Experiments on the effects of small doses on bacteria, fungi, algae, insects, plants and animals are described. Human medical experiments are inhuman and ethically flawed. However, during the familiarity of mankind with ionizing radiation, a large number of population groups were subject to accumulation, exposed to radiation at doses of small but exceeding the natural background radiation. This book analyzes existing, real-life radiation results from survivors of Hiroshima and Nagasaki, Chernobyl and Fukushima, and examines studies of radiation effect on patients, radiologists, crews of long-distant flights and astronauts, on miners of uranium copies, on workers of nuclear industry and on militaries, exposed to ionizing radiation on a professional basis, and on the population of the various countries receiving environmental exposure. The author hopes that this book can mitigate the impact of radiation phobia, which prevails in the public consciousness over the last half century. - Explores the science of radiation and the effects of radiation technologies and biological processes - Analyzes the elementary processes of ionization and excitation - Summarizes information about inner shells ionization and its impact on matter and biological structures - Discusses quantum concepts in biology and clarifies the importance of epigenetics in radiological processes - Includes case studies focusing on humans irradiated by low doses of radiation and its effects




Handbook of Radiotherapy Physics


Book Description

From the essential background physics and radiobiology to the latest imaging and treatment modalities, the updated second edition of Handbook of Radiotherapy Physics: Theory & Practice covers all aspects of the subject. In Volume 1, Part A includes the Interaction of Radiation with Matter (charged particles and photons) and the Fundamentals of Dosimetry with an extensive section on small-field physics. Part B covers Radiobiology with increased emphasis on hypofractionation. Part C describes Equipment for Imaging and Therapy including MR-guided linear accelerators. Part D on Dose Measurement includes chapters on ionisation chambers, solid-state detectors, film and gels, as well as a detailed description and explanation of Codes of Practice for Reference Dose Determination including detector correction factors in small fields. Part E describes the properties of Clinical (external) Beams. The various methods (or ‘algorithms’) for Computing Doses in Patients irradiated by photon, electron and proton beams are described in Part F with increased emphasis on Monte-Carlo-based and grid-based deterministic algorithms. In Volume 2, Part G covers all aspects of Treatment Planning including CT-, MR- and Radionuclide-based patient imaging, Intensity-Modulated Photon Beams, Electron and Proton Beams, Stereotactic and Total Body Irradiation and the use of the dosimetric and radiobiological metrics TCP and NTCP for plan evaluation and optimisation.

National Networks for Radiotherapy Dosimetry Audits


Book Description

The IAEA has a long-standing history of providing radiotherapy dosimetry audits in its Member States. This publication summarizes the methodologies resulting from the work of four coordinated research projects (CRPs) and offers information on experiences collected during the development of dosimetry audit programmes and their implementation at national levels. It also sets the framework and provides advice on the structure of dosimetry audit centres and discusses the general approach for audit development and the necessary background to conduct dosimetry audits in radiotherapy by national organizations. It provides technical and scientific details, as well as practical experiences of the audit steps developed under these CRPs. Any organization developing national audit programmes for radiotherapy can use this publication as a reference and to learn from the experiences of other national audit networks.




Industrial and Medical Nuclear Accidents


Book Description

The peaceful use of atomic energy has given rise to a variety of nuclear accidents from the start. This concerns all forms of use, industrial and medical. For each accident, Industrial and Medical Nuclear Accidents details the contamination of the environment, flora and fauna, and quantifies the effects of ionizing radiation. The book also examines the adverse effects on the health, both physical and mental, of the human populations concerned. The monetary cost is also evaluated. The research presented in this book is based on scientifically recognized publications and on the reports of national and international organizations competent in this field (IAEA, WHO, UNSCEAR, IRSN, etc.). The book contains chapters devoted to the most recent accidents (Chernobyl and Fukushima), with a large body of institutional and academic literature.
