Book excerpt: This report provides guidance on the characteristics, use, and calibration criteria for personnel neutron dosimeters. The report is applicable for neutrons with energies ranging from thermal to less than 20 MeV. Background for general neutron dosimetry requirements is provided, as is relevant federal regulations and other standards. The characteristics of personnel neutron dosimeters are discussed, with particular attention paid to passive neutron dosimetry systems. Two of the systems discussed are used at DOE and DOE-contractor facilities (nuclear track emulsion and thermoluminescent-albedo) and another (the combination TLD/TED) was recently developed. Topics discussed in the field applications of these dosimeters include their theory of operation, their processing, readout, and interpretation, and their advantages and disadvantages for field use. The procedures required for occupational neutron dosimetry are discussed, including radiation monitoring and the wearing of dosimeters, their exchange periods, dose equivalent evaluations, and the documenting of neutron exposures. The coverage of dosimeter testing, maintenance, and calibration includes guidance on the selection of calibration sources, the effects of irradiation geometries, lower limits of detectability, fading, frequency of calibration, spectrometry, and quality control. 49 refs., 6 figs., 8 tabs.

Available in PDF, EPUB and Kindle. Book excerpt: This study assesses the state of personnel neutron dosimetry at DOE facilities. A survey of the personnel dosimetry systems in use at major DOE facilities was conducted, a literature search was made to determine recent advances in neutron dosimetry, and several dosimetry experts were interviewed. It was concluded that personnel neutron dosimeters do not meet current needs and that serious problems exist now and will increase in the future if neutron quality factors are increased and/or dose limits are lowered.

Book excerpt: We developed a personnel neutron dosimetry system based on the electrochemical etching of CR-39 plastic at elevated temperatures. The doses obtained using this dosimeter system are more accurate than those obtained using other dosimetry systems, especially when varied neutron spectra are encountered. This CR-39 dosimetry system does not have the severe energy dependence that exists with albedo neutron dosimeters or the fading and reading problems encountered with NTA film. 3 refs., 4 figs.

Download or read book Intercomparison of High Energy Neutron Personnel Dosimeters written by and published by . This book was released on 1993 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: An intercomparison of high-energy neutron personnel dosimeters was performed to evaluate the uniformity of the response characteristics of typical neutron dosimeters presently in use at US Department of Energy (DOE) accelerator facilities. It was necessary to perform an intercomparison because there are no national or international standards for high-energy neutron dosimetry. The testing that is presently under way for the Department of Energy Laboratory Accreditation Program (DOELAP) is limited to the use of neutron sources that range in energy from about 1 keV to 2 MeV. Therefore, the high-energy neutron dosimeters presently in use at DOE accelerator facilities are not being tested effectively. This intercomparison employed neutrons produced by the 9Be(p, n)9B interaction at the University of Washington cyclotron, using 50-MeV protons. The resulting neutron energy spectrum extended to a maximum of approximately 50-MeV, with a mean energy of about 20-MeV. Intercomparison results for currently used dosimeters, including Nuclear Type A (NTA) film, thermoluminescent dosimeter (TLD)-albedo, and track-etch dosimeters (TEDs), indicated a wide variation in response to identical doses of high-energy neutrons. Results of this study will be discussed along with a description of plans for future work.

Available in PDF, EPUB and Kindle. Book excerpt: Personnel neutron dosimeters using a number of different techniques have been developed for routine use in neutron fields, but all of these dosimeters must be carefully corrected to account for the fact that their response is critically dependent upon the energy distribution of the neutron field. At present, personnel neutron dosimeters are typically calibrated in a standard neutron field (e.g., 252Cf or D2O-moderated 252Cf)- but may then be applied in neutron fields that vary considerably from the calibration field. Some widely used personnel dosimeters, such as TLD-albedo dosimeters, overrespond to low energy neutrons and therefore deliver high readings in fields that are more moderated than the standard field.

Available in PDF, EPUB and Kindle. Book excerpt: A study was conducted to determine the effect of phantom size, shape and composition on the response of an albedo neutron dosimeter. The most important feature was the shape. The dose equivalent rate from a californium neutron source was determined. Ten different dose rates were determined which varied from 2.39 to 3.02 rem/h for the CF source used. (ACR).

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.

Book excerpt: A few inexpensive plastic track etch component, CR-39, polycarbonate, and LR-115 have been added to the albedo dosimeters. This will extend personnel neutron measurement capability, providing information to infer a four energy group spectrum, reduce the expected error in personnel dose assessment, and help clarify the ambiguity that results when personnel must work in more than one neutron facility during the monitoring period.
