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 ...

Retrospective Dosimetry Related to Chronic Environmental Exposure

Radiation Protection Dosimetry, 1998
Radioactive contamination of the environment occurred in the early fifties as a result of the releases from the Mayak plutonium production complex (Southern Urals, Russia). The releases of liquid wastes into the Techa river resulted in chronic exposure of 30,000 residents of the riverside communities. Since 1951 90Sr body burdens have been measured for

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 ...

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 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 ...

Aspects of retrospective ESR dosimetry (invited paper)

Applied Radiation and Isotopes, 1996
A review is given on the major technological and methodological aspects of retrospective ESR dosimetry with tooth enamel. Topics include the collection and preparation of samples, the evaluation, treatment and interpretation of the ESR signals, and the procedure of dose reconstruction.

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 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.

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.

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
