The development and use of fifteen year-old equivalent mathematical phantom for internal dose calculations
… means of obtaining estimates of absorbed dose for children of that age. Dimensions representative of an average fifteen year-old human, obtained from various biological and medical research, were transformed into a mathematical construct of idealized shapes of the exterior, skeletal …

Dose coefficients for radionuclides produced in a spallation neutron source
Internal and external dose coefficient values have been calculated for 14 anthropogenic radionuclides which are not currently presented in Federal Guidance Reports No. 11, 12, and 13 or Publications 68 and 72 of the International Commission on Radiological Protection. Internal dose coefficient …

Πρωτότυπος μετρητής ολοσώμου γ-ακτινοβολίας και η χρήση του στον in-vivo προσδιορισμό του ραδιενεργού καλίου και καισίου
… in several groups of people. The total internal dose was determined for of each group. It was found that this dose was 0.420 mSv for men and 0.275 nSv for women, within the first 2.5 years after the accident. It was also found that children suffered a dose of 0.232 mSv , within the first …

Luminescence dating of Scottish burnt mounds: new investigations in Orkney and Shetland
… detailed characterisation of the external and internal dose rates of samples collected. Additive dose thermoluminescence dating techniques have been applied to extracted feldspar grains. A procedure for correcting temperature-shift due to thermal contact variation has been developed and …

Characterizing canine dose from external beam irradiation
Absorbed dose from Computed Tomography (CT) is a major concern on an individual basis as well as for the collective population due to increased frequency of and dependency on CT scans for diagnostic and therapeutic imaging. Colorado State University recently integrated a large bore multi-slice …

Evaluation of Colloidal Stability and Ecotoxicity of Metal-based Nanoparticles in the Aquatic and Terrestrial Systems
… filter-feed on aggregates, potentially elevating internal dose, and thus higher mortality. Maize root anatomy showed differential alterations upon exposure to AgNPs, ZnONPs, or their ions.</p> <p>Overall, various metal-based nanoparticles revealed lower toxicity than their ions against multiple …

Tritium Matters: Constructing Nuclearity and Navigating Ambivalence of a Unique Material
… beta particle which poses a potential risk as internal dose. I argue that the nuclearity processes constituting various conceptualizations of tritium provide insight into navigating the complex sociotechnical relationships between humans and nuclear technology. Additionally, I anticipate …

Polonium-210 in Freshwater Environments: Analytical Advances, Predictive Modelling, Food Web Transfer and Dose Assessment
… radioecological risk assessments. Finally, dose assessments showed that benthic invertebrates experienced the highest internal exposures, while fish viscera disproportionately contributed to whole-body dose burdens. Collectively, this work provides new tools, empirical data and predictive …
