Optically stimulated luminescence techniques in retrospective dosimetry

Radiation Physics and Chemistry, 2001
Abstract Optically stimulated luminescence signals from natural quartz and feldspar are now used routinely in dating geological and archaeological materials. More recently they have also been employed in accident dosimetry, i.e. the retrospective assessment of doses received as a result of a nuclear accident.

New luminescence measurement facilities in retrospective dosimetry

Radiation Measurements, 2012
Abstract This paper gives a review of recent developments in luminescence measurement facilities on the Riso TL/OSL reader including radio-luminescence (RL), exo-electron and violet stimulation attachments, and a method for characterising and if necessary correcting for beta irradiation source non-uniformity.

Technologies for retrospective radiation dosimetry

Radiation Protection Dosimetry
Abstract Radiation dosimetry is an important task for assessing the biological damages created in human being due to ionising radiation exposure. Ionising radiation being invisible and beyond the perception of human natural sensors, the dosimetry equipments/systems are the utmost requirement for its measurement. Retrospective measurement

Accidental and retrospective dosimetry using TL method

Radiation Physics and Chemistry, 2012
Abstract Retrospective dosimetry is one of the most important tools of accidental dosimetry for dose estimation when dose measurement was not planned. In the affected area many objects can be applied as natural dosimeters. The paper discusses our recent investigations on various electronic components and common salt (NaCl) having useful ...

Retrospective Accident Dosimetry Using Environmental Materials

Radiation Protection Dosimetry, 1993
Abstract Retrospective dosimetry of radiation accidents can be accomplished with the aid of environmental materials which were exposed during the time of the accident. The primary requirements for such dosemeters include: (1) the absence of a saturating natural dose accumulated over geological time periods, (2) the ability to retain a ...

Metabolism in tooth enamel and reliability of retrospective dosimetry

Applied Radiation and Isotopes, 2000
Most of the radiation centers in tooth enamel and bones are formed by the reactions COOH + gamma-->CO2- + H+, and CO2 + e- -->CO2-. These centers can be easily changed by metabolism and have a low stability in living organisms. The efficiency of CO2- radical production by irradiation is substantially different for teeth and bones in living rat, dead ...

Retrospective Dosimetry Analyses of Reactor Vessel Cladding Samples

Journal of ASTM International, 2012
Reactor pressure vessel cladding samples for Ringhals Units 3 and 4 in Sweden were analyzed using retrospective reactor dosimetry techniques. The objective was to provide the best estimates of the neutron fluence for comparison with neutron transport calculations.

Wide Scale EPR Retrospective Dosimetry: Results and Problems

Radiation Protection Dosimetry, 1997
The results of the first wide-scale application of electron paramagnetic resonance (EPR) with tooth enamel for retrospective dosimetry for permanent residents of Borovskii and Zhukovskii districts (Kaluga region, Russia) are presented. Since these districts have never been radioactively contaminated, their population could be used for comparison ...

Retrospective Dosimetry Needs from an IAEA Perspective

Radiation Protection Dosimetry, 1998
Review and investigation of radiation related accidents is an important part of the International Atomic Energy Agency objective to achieve the safe use of radiation, radioactive material and nuclear energy. In the 40 years since it was established, the IAEA has reviewed or been directly involved in a number of accident investigations.

The Chernobyl experience in the area of retrospective dosimetry

Journal of Radiological Protection, 2012
The Chernobyl accident, which occurred on 26 April 1986 at a nuclear power plant located less than 150 km north of Kiev, was the largest nuclear accident to date. The unprecedented scale of the accident was determined not only by the amount of released activity, but also by the number of workers and of the general public involved, and therefore exposed
