New trends in clinical and retrospective dosimetry

Bio-Algorithms and Med-Systems, 2023
Selecting the proper dosimeter and methodology is crucial for accurate dose measurement, especially since the requirements are different for clinical and retrospective dosimetry. Regardless of the field-radiotherapy, X-ray diagnostic radiology or nuclear medicineefforts are continuously being made to improve radiation measurement accuracy through the ...

Desiccants for retrospective dosimetry using optically stimulated luminescence (OSL)

open access: yesRadiation Measurements, 2015
Optically stimulated luminescence (OSL) was used to test different kinds of desiccants for their potential use in retrospective dosimetry. Desiccants are used for the purpose of absorbing liquids and can be found in a number of items which may be found ...

Retrospective dosimetry for external exposures

International Congress Series, 2002
Abstract Two methods of retrospective dosimetry for external exposures are reviewed. First, electron paramagnetic resonance (EPR or electron spin resonance, ESR) with teeth has its strengths in the determination of individual exposures, acute or protracted, that may have occurred several decades ago. The method is best studied for photon fields. The

Optically Stimulated Luminescence in Retrospective Dosimetry

Radiation Protection Dosimetry, 2002
Since the beginning of the 1990s the exploration of optically stimulated luminescence (OSL) in retrospective accident dosimetry has driven an intensive investigation and development programme at Risø into measurement facilities and techniques. This paper reviews some of the outcomes of this programme, including the evaluation of the single-aliquot ...

Retrospective Dosimetry for Latvian Workers at Chernobyl

Radiation Protection Dosimetry, 2001
Between 1986 and 1991 approximately 6500 Latvian inhabitants were recruited for clean-up work at the Chernobyl nuclear power plant. Their absorbed doses are usually unknown, because less than half of them had their external exposure officially documented.

Retrospective Biological Dosimetry of Absorbed Radiation

Radiation Protection Dosimetry, 2001
Frequencies of chromosomal translocations in human peripheral blood lymphocytes irradiated in vitro by 200 kV X rays have been estimated by the fluorescence in situ hybridisation (FISH) technique. Probes specific for whole chromosomes 1, 3 and 4 were labelled with, biotin 16 dUTP + digoxigenin 11 dUTP; biotin 16 dUTP and digoxigenin 11 dUTP ...

Application of Different Nuclides in Retrospective Dosimetry

Journal of ASTM International, 2012
Abstract The activities of nuclides produced via the neutron irradiation of reactor pressure vessel (RPV) steel are used to validate respective fluence calculations. Niobium, nickel, and technetium isotopes from RPV trepans of the decommissioned NPP Greifswald (VVER-440) have been analyzed.

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 ...
