Abstract

This paper describes the creation of a voxel-based dosimetric model of a toadfish (Halobatrachus didactylus) from available CT images in which 29 organs are identified and segmented using 3D Slicer software. To validate the present dosimetric model Specific Absorbed Fractions (SAFs) were calculated for ten vital organs as sources and all targets, for discrete energies of electrons and photons. Then, the obtained dosimetric coefficients were compared to those calculated in similar organs in a voxel-based phantom of a trout fish (Oncorhynchus mykiss). The results showed a general agreement between the comparative dosimetric data, highlighting the validity of our dosimetric model for Halobatrachus didactylus. We conclude that the current dosimetric fish model can be applied in future research to evaluate dosimetry calculations related to radiation exposure in regions surrounding the Fukushima accident site.

基于体素的双角蟾计算体模的开发与验证，用于海洋环境辐射防护研究

本文描述了从可用的CT图像中创建一个基于体素的剂量学模型的蟾蜍鱼（Halobatrachus didactylus），其中29个器官被识别和使用3D切片器软件分割。为了验证目前的剂量学模型，计算了10个重要器官作为源和所有目标，电子和光子的离散能量的比吸收分数（SAFs）。然后，将获得的剂量学系数与基于体素的鳟鱼（Oncorhynchus mykiss）模型中类似器官的剂量学系数进行比较。结果表明，比较剂量学数据之间基本一致，突出了我们的剂量学模型的有效性。我们的结论是，目前的剂量学鱼类模型可以应用于未来的研究，以评估与福岛事故现场周围地区辐射暴露相关的剂量学计算。

期刊介绍： The Journal of Environmental Radioactivity provides a coherent international forum for publication of original research or review papers on any aspect of the occurrence of radioactivity in natural systems. Relevant subject areas range from applications of environmental radionuclides as mechanistic or timescale tracers of natural processes to assessments of the radioecological or radiological effects of ambient radioactivity. Papers deal with naturally occurring nuclides or with those created and released by man through nuclear weapons manufacture and testing, energy production, fuel-cycle technology, etc. Reports on radioactivity in the oceans, sediments, rivers, lakes, groundwaters, soils, atmosphere and all divisions of the biosphere are welcomed, but these should not simply be of a monitoring nature unless the data are particularly innovative.
