dosimetry for radiodiagnostics (2). It has been used for personal dosimetry (as a replacement for film badges) and medical dosimetry for both radiotherapy and radiodiagnostics (2,3). The dosimeters (nanoDot, Landauer, Glenwood, Illinois) used in our study are OSL based, small (1 1 0.2 cm), environmentally stable, and highly accurate and precise within the exposures measured in the study (3). Ad...
The most frequently used and the best established method of biological dosimetry at present is the dicentric chromosome assay, which is poorly suitable for a mass casualties scenario. This gives rise to the need for the development of new, high-throughput assays for rapid identification of the subjects exposed to ionizing radiation. In the present study, we tested the usefulness of gene express...
The World Health Organization (WHO) held a consultation meeting at WHO Headquarters, Geneva, Switzerland, December 17-18, 2007, to develop the framework for a global biodosimetry network. The WHO network is envisioned to enable dose assessment using multiple methods [cytogenetics, electron paramagnetic resonance (EPR), radionuclide bioassays, etc.]; however, the initial discussion focused on th...
The paper is devoted to review of development and application of EPR dosimetry with teeth in Ukraine. It deals with specific features of the EPR dosimetry protocol, which was developed and is practically used in SCRM for retrospective dosimetry of clean-up workers (liquidators). Extensive methodological research was conducted in SCRM in order to develop an original version of EPR dosimetric pro...
Biological indicators would be of use in radiation dosimetry in situations where an exposed person is not wearing a dosimeter, or when physical dosimeters are insufficient to estimate the risk caused by the radiation exposure. In this work, we investigate the use of gene expression as a dosimeter. Gene expression analysis was done on 15,222 genes of Drosophila melanogaster (fruit flies) at days...
Creating a sustainable network in biological and retrospective dosimetry that involves a large number of experienced laboratories throughout the European Union (EU) will significantly improve the accident and emergency response capabilities in case of a large-scale radiological emergency. A well-organised cooperative action involving EU laboratories will offer the best chance for fast and trust...
Several national and international organizations have developed various types and levels of external audits for radiotherapy dosimetry, either based on on-site review visits or using mailed dosimetry systems. Three major TLD (thermoluminescent dosimetry) networks make available postal dose audits to a large number of radiotherapy centres on a regular basis. These are the IAEA/WHO TLD postal dos...
