Book excerpt: This report both complements and extends Technical Reports Series No. 277/2, Absorbed Dose Determination in Photon and Electron Beams - An International Code of Practice, IAEA Technical Reports Series No. 277/2. It describes options and how to calibrate plane parallel ionization chambers, against air kerma or absorbed dose to water standards at cobalt-60 gamma ray energies. The use of these chambers to calibrate therapy electron beams, as well as relative dose measurements for photon and electron beams, is presented. This publication also updates some of the data and concepts used in Technical Reports Series No. 277/2. It fills gaps in the latter report with respect to plane parallel chambers with a view to improve accuracy in radiotherapy when these chambers are used.

Download or read book Radiation Dosimetry Instrumentation and Methods written by Gad Shani and published by CRC Press. This book was released on 2000-12-28 with total page 506 pages. Available in PDF, EPUB and Kindle. Book excerpt: Radiation dosimetry has made great progress in the last decade, mainly because radiation therapy is much more widely used. Since the first edition, many new developments have been made in the basic methods for dosimetry, i.e. ionization chambers, TLD, chemical dosimeters, and photographic films. Radiation Dosimetry: Instrumentation and Methods, Second Edition brings to the reader these latest developments. Written at a high level for medical physicists, engineers, and advanced dosimetrists, it concentrates only on evolvement during the last decade, relying on the first edition to provide the basics.
Download or read book Fundamentals of Ionizing Radiation Dosimetry written by Pedro Andreo and published by John Wiley & Sons. This book was released on 2017-05-17 with total page 720 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new, comprehensively updated edition of the acclaimed textbook by F.H. Attix (Introduction to Radiological Physics and Radiation Dosimetry) taking into account the substantial developments in dosimetry since its first edition. This monograph covers charged and uncharged particle interactions at a level consistent with the advanced use of the Monte Carlo method in dosimetry; radiation quantities, macroscopic behaviour and the characterization of radiation fields and beams are covered in detail. A number of chapters include addenda presenting derivations and discussions that offer new insight into established dosimetric principles and concepts. The theoretical aspects of dosimetry are given in the comprehensive chapter on cavity theory, followed by the description of primary measurement standards, ionization chambers, chemical dosimeters and solid state detectors. Chapters on applications include reference dosimetry for standard and small fields in radiotherapy, diagnostic radiology and interventional procedures, dosimetry of unsealed and sealed radionuclide sources, and neutron beam dosimetry. The topics are presented in a logical, easy-to-follow sequence and the text is supplemented by numerous illustrative diagrams, tables and appendices. For senior undergraduate- or graduate-level students and professionals.

This book was released on 2000 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Code of Practice, which has also been endorsed by WHO, PAHO and ESTRO, fulfils the need for a systematic and internationally unified approach to the calibration of ionization chambers in terms of absorbed dose to water and to the use of these detectors in determining the absorbed dose to water for the radiation beams used in radiotherapy. It provides a methodology for the determination of absorbed dose to water in the low, medium and high energy photon beams, electron beams, proton beams and heavy ion beams used for external radiation therapy.

Download or read book The Dosimetry of Ionizing Radiation written by Kenneth Kase and published by Elsevier. This book was released on 2012-12-02 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Dosimetry of Ionizing Radiation, Volume I focuses on the development in radiation dosimetry, which has its origin in the medical application of ionizing radiation with the discovery of X-rays. This book discusses the irradiation of human beings and the biosphere by ionizing radiation from different sources, which is subjected to increased concern and interest due to its possible health effects. Comprised of six chapters, this volume starts with an overview of the factors determining the conversion of the imparted energy into a detectable signal. This text then explores the theoretical basis of microdosimetry and illustrates the numerical data, experimental techniques, and applications of essential concepts and results. Other chapters consider the application of instruments in dose measurements. This book discusses as well the application of radiotherapy for the treatment of malignant diseases. The final chapter deals with the recommended model parameters for internal dosimetry calculations in occupational radiation protection. Physicists, radiation physicists, scientists, and research institutes will find this book useful.
Download or read book Calibration of Photon and Electron Beams with an Extrapolation Chamber written by Corey E. Zankowski and published by . This book was released on 1997 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: "A variable air-volume, parallel-plate, extrapolation chamber forming an integral part of a Solid-WaterTM phantom was built to determine the absorbed dose in Solid-WaterTM directly. The sensitive air-volume of the extrapolation chamber is controlled through the movement of the chamber piston by means of a micrometer mounted to the phantom body. The relative displacement of the piston is monitored by a mechanical distance travel indicator with a precision on the order of 0.002 mm. Irradiations were carried out with cobalt-60 gamma. rays, x-ray beams ranging from 4 to 18 MV, and electron beams between 6 and 22 MeV. The absorbed dose at a given depth in Solid-WaterTM is proportional to the ionization gradient measured in the Bragg-Gray cavity region with a Solid-WaterTM embedded extrapolation chamber. Measured charge is corrected for ion recombination and ion diffusion in the chamber air volume according to a comprehensive model for charge loss in an ionization chamber. The discrepancies between doses determined with our uncalibrated phantom-embedded extrapolation chamber and doses obtained with calibrated Farmer-type cylindrical ionization chambers following the AAPM-TG21 and AAPM-TG25 dosimetry protocols are less than 1% for photon and electron beams at all clinical megavoltage energies. Uncalibrated extrapolation chambers thus offer a simple and practical alternative to other techniques used in output measurements of megavoltage photon and electron beams." --
