Available in PDF, EPUB and Kindle. Book excerpt: Estimates of biological effects associated with exposure to external radiation fields are generally based on the measured response of passive personnel dosimetry systems to the incident radiation. The increasing number of persons occupationally exposed to mixed neutron and gamma fields and recent questions concerning the relative biological hazards of different types of radiation have emphasized the need for accurate personnel radiation dose measurements. The performance characteristics of various neutron and gamma personnel dosimetry systems under actual mixed-field conditions have been determined. Analysis of the results indicates that significant inaccuracies can occur in neutron and gamma dose measurements in mixed radiation fields unless dosimeter performance and characteristics of the monitoring environment are considered in dosimeter evaluation. Neutron dose measurement accuracies could be improved by using dosimeters more suited to the anticipated radiation fields, calibrating dosimeters with sources appropriate for the energy spectra to be measured, applying correction factors to account for dosimeter performance in incident radiation fields, and standardizing the basis of reported dose equivalents. With regard to gamma monitoring, intercomparison results indicate that the selection of a basic dosimeter type which is relatively insensitive to neutrons is of great importance for accurate dose measurements in mixed fields.

Download or read book Techniques and Management of Personnel Thermoluminescence Dosimetry Services written by M. Oberhofer and published by Springer Science & Business Media. This book was released on 1993-10-31 with total page 462 pages. Available in PDF, EPUB and Kindle. Book excerpt: The International Commission on Radiological Protection and the Euratom Council directive have specified that workers exposed to ionizing radiation shall be subjected to individual dose monitoring. In the past, individual doses have almost always been monitored by film badge dosimeters, but thermoluminescent dosimeters (TLDs) are now coming into widespread use, principally due to the availability of automated readout systems. Techniques and Management of Personnel Thermoluminescence Dosimetry Services gives details of the operation of and experience gained with a number of large-scale TL personnel dosimetry services, with particular attention being paid to the management aspects of such services. For technical and administrative personnel in TLD services, TLD system designers, staff of licensing authorities concerned with dosimetric licensing, students of radiation protection, especially in the area of protection from ionizing radiation. A basic knowledge of atomic and nuclear physics is assumed, and a training in radiation protection or health physics would be an advantage.

Download or read book Optically Stimulated Luminescence Dosimetry written by L. Boetter-Jensen and published by Elsevier. This book was released on 2003-10-24 with total page 375 pages. Available in PDF, EPUB and Kindle. Book excerpt: Optically Stimulated Luminescence (OSL) has become the technique of choice for many areas of radiation dosimetry. The technique is finding widespread application in a variety of radiation dosimetry fields, including personal monitoring, environmental monitoring, retrospective dosimetry (including geological dating and accident dosimetry), space dosimetry, and many more. In this book we have attempted to synthesize the major advances in the field, covering both fundamental understanding and the many applications. The latter serve to demonstrate the success and popularity of OSL as a dosimetry method. The book is designed for researchers and radiation dosimetry practitioners alike. It delves into the detailed theory of the process from the point of view of stimulated relaxation phenomena, describing the energy storage and release processes phenomenologically and developing detailed mathematical descriptions to enable a quantitative understanding of the observed phenomena. The various stimulation modes (continuous wave, pulsed, or linear modulation) are introduced and compared. The properties of the most important synthetic OSL materials beginning with the dominant carbon-doped Al2O3, and moving through discussions of other, less-well studied but nevertheless important, or potentially important, materials. The OSL properties of the two most important natural OSL dosimetry material types, namely quartz and feldspars are discussed in depth. The applications chapters deal with the use of OSL in personal, environmental, medical and UV dosimetry, geological dating and retrospective dosimetry (accident dosimetry and dating). Finally the developments in instrumentation that have occurred over the past decade or more are described. The book will find use in those laboratories within academia, national institutes and the private sector where research and applications in radiation dosimetry using luminescence are being conducted. Potential readers include personnel involved in radiation protection practice and research, hospitals, nuclear power stations, radiation clean-up and remediation, food irradiation and materials processing, security monitoring, geological and archaeological dating, luminescence studies of minerals, etc.

Download or read book Radiation Dosimetry Data Management Using VAX C FMS RMS DCL and Oracle written by and published by . This book was released on 1991 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: The External Dosimetry Badge System was developed to support the radiation protection program at Los Alamos National Laboratory. The radiation protection program is responsible for monitoring external radiation exposures to approximately 7,500 Laboratory employees, visitors and contractors each month. External radiation exposure is measured using thermoluminescent dosimeters (TLDs). The system is used to control the assembly and distribution of TLD badges. The system monitors badge return and disassembly at the end of each month, and analyzes the TLDs to determine individual radiation exposure levels. Results are reported and stored in a database designed to maintain detailed individual exposure records. The system maintains a complete history of annual summaries for external exposures. The system is user-friendly with user prompts, menus, and extensive help functions. The completely menu-driven system uses VAX C, VAX Forms Management System, VMS Record Management Services, VMS Digital Command Language, and the Oracle Relational Database Management System. Design and development issues faced, and methods and techniques used in developing the system will be described. Topics discussed include consistent user interface design approaches, considerations for using VAX/VMS programming tools versus Oracle development tools to develop and implement the application, and overall system benefits. 3 refs.

Book excerpt: After outlining briefly the rationale for personnel radiation monitoring with integrating detectors, a review is presented of some developments which have taken place in personnel and environmental dosimetry during the past 3.5 years. The results of a pilot field experiment concerning the stability of film and thermoluminescent dosimeters (TLDs) in four Latin-American countries are summarized. It shows that film dosimeters should be used only with caution, and in locations with a moderate climate. A survey is being conducted on the current status and trends in personnel monitoring, involving detailed questioning of over 150 laboratories in about forty countries to obtain information on the type of service and detectors, evaluation and recordkeeping, additional applications, problem and development areas, intercomparisons, practical experiences with different systems, administrative and legal aspects, etc. According to the preliminary results, the trend is away from photographic film and towards mostly automatic TLD systems, not only in the industrialized countries but also in several of the larger and more advanced developing countries. The need for higher quality standards and frequent performance tests under realistic conditions is emphasized. Differences in the requirements for personnel and stationary environmental dosimeters are outlined. As evidenced by the results of a recent international intercomparison of such dosimeters under laboratory and field conditions, involving 56 dosimeter sets from eleven countries, reasonably accurate results can be obtained with several TLD systems including LiF, CaSO$sub 4$:Dy, and CaF2:Mn; however CaF2:Dy is less reliable than the others and film is not adequate at all. Transit doses were found to be erratic and frequently high. Limitations in the assessment of population doses from stationary detector readings are discussed. (auth).

This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Arrangements for personal monitoring have evolved as dose limits and practices using radiation have developed. Therefore, new approaches involving more personal dosimetry are required, and methods are needed that can be used to predict probable dose levels so that risk assessments can be prepared to determine the level of dose monitoring for individual staff members. The authors set out recommendations designed to help radiation protection practitioners and healthcare workers assess exposure levels for personnel and determine monitoring requirements based on established rules. This book is essential reading for medical physicists in radiation protection, diagnostic radiology and nuclear medicine, as well as radiographers and technologists due to changes in global dosimetry requirements. Additionally, it presents guidelines for medical physicists and others using radiation. Part of IPEM-IOP Series in Physics and Engineering in Medicine and Biology.
