Electron spin resonance (ESR) measurement data of 98 teeth from atomic-bomb survivors who received various radiation doses were analyzed in terms of possible solar light exposure by tooth position. Each tooth was divided into buccal and lingual parts for independent ESR measurement. We found that average buccal doses were larger than their corresponding lingual doses by 0.48 +/- 0.30 Gy (first ...
To provide the best opportunities for life-saving interventions in the event of a radiological or nuclear threat, there is an urgent need to improve the speed and efficiency of biodosimetric assays for triage and therapy. A rapid automated biodosimetric system used to assess thousands of individual radiation exposure doses is helpful to curb mass panic, and to conserve limited medical resources...
The Fukushima nuclear disaster caused by the earthquake and tsunami on March 11, 2011 is believed to be the worst nuclear accident since the Chernobyl disaster in 1986. The Korean government is providing support to Japan and is also trying to protect the people from the hazards of ionizing radiation. To this end, Korean rescuers have been dispatched to the disaster-struck areas to assist in the...
PURPOSE To evaluate the importance of annual intercomparisons for maintaining the capacity and capabilities of a well-established biodosimetry network in conjunction with assessing efficient and effective analysis methods for emergency response. MATERIALS AND METHODS Annual intercomparisons were conducted between laboratories in the Canadian National Biological Dosimetry Response Plan. Interc...
BACKGROUND The aim of this study was to screen molecular biomarkers for biodosimetry from DNA repair-related gene expression profiles. MATERIAL/METHODS Mice were subjected to whole-body exposure with 60Co gamma rays with a dose range of 0-8 Gy at a dose rate of 0.80 Gy/min. RNA was extracted from the peripheral blood of irradiated mice at 4, 8, 12, 24 and 48hrs post-irradiation. The mRNA tran...
The development of, and results from an image analysis system are presented for automated detection and scoring of micronuclei in human peripheral blood lymphocytes. The system is part of the Rapid Automated Biodosimetry Tool, which was developed at the Center for High-Throughput Minimally Invasive Radiation Biodosimetry for rapid radiation dose assessment of many individuals based on single fi...
Humans are exposed to ionizing radiation not only through background radiation but also through the ubiquitous presence of devices and sources that generate radiation. With the expanded use of radiation in day-to-day life, the chances of accidents or misuse only increase. Therefore, a thorough understanding of the dynamic effects of radiation exposure on biological entities is necessary. The bi...
