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 dosimetry using synthesized nano-structure hydroxyapatite

Radiation Protection Dosimetry, 2010
Micro and nano-structure hydroxyapatite samples were synthesized via several different methods. The samples were characterised utilising the Fourier transmission infra-red, scanning electron microscope and X-ray diffraction methods, to find out the structure most similar to human tooth enamel, and the best method was found.

Retrospective Dosimetry using Unheated Quartz: A Feasibility Study

Radiation Protection Dosimetry, 2002
Most attempts to apply retrospective dosimetry to building materials have made use of heated (sensitised) items such as brick or tile ceramic. Unfired materials, such as concrete, are far more widespread in the industrial environment, but unfortunately these cannot be assumed to contain a negligible dose at the time of construction.

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 ...

EPR Retrospective Dosimetry with Fingernails

Health Physics, 2014
For localized irradiation to hands, in case of sources accidentally handled, it is very difficult to estimate the dose distribution by calculation. Doses may reach several tens of grays, and the dose distribution is usually very heterogeneous. Until recently, doses in such situations could be estimated only by analysis of bone biopsies using Electron ...

Retrospective dosimetry with ceramics

Radiation Measurements, 1997
Abstract This paper reviews recent progress that has been made in the application of luminescence techniques with ceramic materials to the problem of dose reconstruction at: Hiroshima and Nagasaki; areas downwind of the Nevada Test Site; regions of Belarus, the Russian Federation and the Ukraine contaminated by fallout from Chernobyl; settlements ...

Retrospective dosimetry based on egg shells

Applied Radiation and Isotopes, 1994
Abstract Irradiated egg shells exhibit a paramagnetic center at g = 2.0018. The center is stable up to temperatures of 150°C and against u.v. light. The center concentration as determined by electron paramagnetic resonance spectroscopy increases with absorbed dose.

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.

Retrospective Biological Dosimetry by FISH

2007
This chapter reviews the present status of applying fluorescence in situ hybridisation (FISH) for retrospective biological dosimetry by chromosomal analysis. The technique helps to overcome a major drawback, the limited persistence of signal, of the more traditional method of dicentric analysis.

Retrospective dosimetry with alumina substrate from electronic components

Radiation Protection Dosimetry, 2011
Alumina substrate can be found in electronic components used in portable electronic devices. The material is radiation sensitive and can be applied in dosimetry using thermally or optically stimulated luminescence. Electronic portable devices such as mobile phones, USB flash discs, mp3 players, etc., which are worn close to the body, can represent ...
