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.

This book was released on 1998 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: Panasonic thermoluminescent dosimeters (TLDs) are used as the photon dose assessment part of the personal nuclear accident dosimeter (PNAD) and may be used for the same purpose with the fixed nuclear accident dosimeter (FNAD). To demonstrate compliance with 10CFR835.1304 (and, its predecessor, DOE Order 5480.11), several sets of dosimeters were irradiated to photon doses above the upper limit of the DOELAP testing standard, DOE/EH-0026 and DOE/EH-0027. The upper range of the test was 10,000 rads, using both low energy (70 keV) and high energy (662 keV and 1,332 keV) sources. The testing indicated that the Panasonic TLD system is capable of meeting the requirements of 10CFR835.1304 and DOE Order 5480.11.

Available in PDF, EPUB and Kindle. Book excerpt: Providing accurate neutron dosimetry for a variety of neutron energy spectra is a formidable task for any dosimetry system. Unless something is known about the neutron spectrum prior to processing the dosimeter, the calculated dose may vary greatly from that actually encountered; that is until now. The entrance of bubble detector technology into the field of neutron dosimetry has eliminated the necessity of having an a priori knowledge of the neutron energy spectra. Recently, a new approach in measuring personnel neutron dose equivalent was developed at Oak Ridge National Laboratory. By using bubble detectors in combination with current thermoluminescent dosimeters (TLDs) as a Combination Personnel Neutron Dosimeter (CPND), not only is it possible to provide accurate dose equivalent results, but a simple four-interval neutron energy spectrum is obtained as well. The components of the CPND are a Harshaw albedo TLD and two bubble detectors with theoretical energy thresholds of 100 key and 1500 keV. Presented are (1) a synoptic history surrounding emergence of bubble detector technology, (2) a brief overview of the current theory on mechanisms of interaction, (3) the data and analysis process involved in refining the response functions, (4) performance evaluation of the original CPND and a reevaluation of the same data under the modified method, (5) the procedure used to determine the reference values of component fluence and dose equivalent for field assessment, (6) analysis of the after-modification results, (7) a critique of some currently held assumptions, offering some alternative explanations, and (8) thoughts concerning potential applications and directions for future research.

This book was released on 1968 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report discusses CaF2:Mn and LiF thermoluminescent dosimeters (TLD). CaF2:Mn vacuum tube TLD and 1/2 mini TLD provide reliable gamma-exposure measurements from 5,000 to 50,000 R. Used with energy discrimination and 6LiF thermal neutron shields, the TLD are energy independent and thermal neutron insensitive. The LiF TLD rods provide inexpensive tissue-equivalent measurements of gamma radiation from 10 to 10,000 R. Thermal neutron response can be made insignificant by using 7Li enriched phosphor. Numerical corrections can be made for fast neutron contributions to LiF and CaF2:Mn TLD response.

Book excerpt: Thermoluminescent dosimeters (TLDs), particularly CaF2:Mn, are often used as photon dosimeters in mixed (n/[gamma]) field environments. In these mixed field environments, it is desirable to separate the photon response of a dosimeter from the neutron response. For passive dosimeters that measure an integral response, such as TLDs, the separation of the two components must be performed by post-experiment analysis because the TLD reading system cannot distinguish between photon and neutron produced response. Using a model of an aluminum-equilibrated TLD-400 chip, a systematic effort has been made to analytically determine the various components that contribute to the neutron response of a TLD reading. The calculations were performed for five measured reactor neutron spectra and one theoretical thermal neutron spectrum. The five measured reactor spectra all have dosimetry quality experimental values for aluminum-equilibrated TLD-400 chips. Calculations were used to determined the percentage of the total TLD response produced by neutron interactions in the TLD and aluminum equilibrator. These calculations will aid the Sandia National Laboratories-Radiation Metrology Laboratory (SNL-RML) in the interpretation of the uncertainty for TLD dosimetry measurements in the mixed field environments produced by SNL reactor facilities.

Available in PDF, EPUB and Kindle. Book excerpt: Neutron dosimetry has been extensively studied at Hanford since the mid-1940s. At the present time, Hanford contractors use thermoluminescent dosimeter (TLD)-albedo dosimeters to record the neutron dose equivalent received by workers. The energy dependence of the TLD-albedo dosimeter has been recognized and documented since introduced at Hanford in 1964 and numerous studies have helped assure the accuracy of dosimeters. With the recent change in Hanford's mission, there has been a significant decrease in the handling of plutonium tetrafluoride, and an increase in the handling of plutonium metal and plutonium oxide sources. This study was initiated to document the performance of the current Hanford TLD-albedo dosimeter under the low scatter conditions of the calibration laboratory and under the high scatter conditions in the work place under carefully controlled conditions at the Plutonium Finishing Plant (PFP). The neutron fields at the PFP facility were measured using a variety of instruments, including a multisphere spectrometer, tissue equivalent proportional counters, and specially calibrated rem meters. Various algorithms were used to evaluate the TLD-albedo dosimeters, and the results are given in this report. Using current algorithms, the dose equivalents evaluated for bare sources and sources with less than 2.5 cm (1 in.) of acrylic plastic shielding in high scatter conditions typical of glove box operations are reasonably accurate. Recently developed CR-39 track etch dosimeters (TEDs) were also exposed in the calibration laboratory and at the PFP. The results indicate that the TED dosimeters are quite accurate for both bare and moderated neutron sources. Until personnel dosimeter is available that incorporates a direct measure of the neutron dose to a person, technical uncertainties in the accuracy of the recorded data will continue.
