Download or read book Accidental Overexposure of Radiotherapy Patients in San Jose Costa Rica written by International Atomic Energy Agency and published by . This book was released on 1998 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes the assessment made of an accidental overexposure of radiotherapy patients that occurred at the San Juan de Dios Hospital in San José, Costa Rica, in August and September 1996. The assessment was carried out by an Expert Team convened by the IAEA in July 1997 at the request of the Government of Costa Rica. The findings of the Expert Team's assessment are presented in two parts: (1) an evaluation of the doses to patients by analysing the treatment records and physical measurements; and (2) a medical examination of patients, together with the autopsy findings for those who died. Thirty cross-sectional images are reproduced that show the dose reconstructions made for some of the patients. The purpose of the report is to foster information exchange with a view to preventing similar accidents elsewhere in the future.

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.
Download or read book Radiation written by Ilya Obodovskiy and published by Elsevier. This book was released on 2019-03-09 with total page 720 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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

Download or read book The Radiological Accident in Soreq written by International Atomic Energy Agency and published by . This book was released on 1993 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: On 21 June 1990 a fatal radiological accident occurred at an industrial irradiation facility at Soreq, Israel. An operator entered the irradiation room by circumventing safety systems and was acutely exposed, with an estimated whole body dose of 10-20 Gy. The accident, like earlier accidents at similar irradiators, was the consequence of the contravention of operating procedures. An IAEA review team investigated the causes of the accident. This report presents its findings and recommendations and describes the clinical management of the patient, particularly of the haematological phase. The medical treatment included the use of emerging therapies with haematopoietic growth factor drugs which may rescue the overexposed patient, albeit in this case only temporarily. The report is intended for regulatory authorities responsible for the regulation and inspection of irradiators, operating organizations and physicians who may need to treat overexposed patients.

Download or read book The Radiological Accident in Cochabamba written by International Atomic Energy Agency and published by IAEA. This book was released on 2004 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: In April 2002 an accident involving an industrial radiography source containing Ir-192 occurred in Cochabamba, Bolivia, some 500 km from the capital, La Paz. The source, in a remote exposure container, remained exposed within a guide tube, although this was not known at the time. The container, the guide tube and other equipment were transported from Cochabamba to La Paz as cargo on a passenger bus. This bus had a full load of passengers for most of the eight hour journey. The equipment was subsequently collected by employees of the company concerned and transferred by taxi to the company's shielded facility. This publication gives an account of the event, the doses received and the medical assessment. It also presents information relevant to national authorities and regulatory organizations, emergency planners and a broad range of specialists, including physicists, radiation protection officers and medical specialists. It is hoped that dissemination of the information contained in the report will help reduce the likelihood of similar accidents occurring or, if they do occur, help mitigate their consequences
Download or read book The Radiological Accident in San Salvador written by International Atomic Energy Agency and published by International Atomic Energy Agency. This book was released on 1990 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: On 5 February 1989, a radiological accident occurred at an industrial irradiation facility near San Salvador, El Salvador. Medical products are sterilized at the facility by irradiation by means of an intensely radioactive cobalt-60 source in a movable source rack. This source rack became stuck in the irradiation position. The operator bypassed the irradiator's degraded safety systems and entered the radiation room with two other workers to free the source rack manually. The three men were exposed to high radiation doses and developed the acute radiation syndrome. They received initial hospital treatment in San Salvador and subsequent, more specialized treatment in Mexico City. The legs and feet of two men were so seriously injured that amputation was required. The worker who had been most exposed died six and a half months after the accident from lung damage due to irradiation complicated by injury sustained during treatment. The report describes the accident and the response to it and presents lessons derived for operators and suppliers of irradiators, national authorities, medical staff and international organizations. Detailed information on dosimetric and medical aspects of the accident is presented in appendices and annexes.
