The nuclear energy is widely used as a new energy source due to the increasing depletion of fossil fuels. In the development of nuclear energy and technology, people are paying more and more attention to the issue of nuclear radiation protection. As a result, advanced computer technology has become a new way to solve nuclear radiation safety issues. This paper proposes to utilize CUDA-based ray-casting volume rendering to build an interactive nuclear radiation visualization system to solve the nuclear radiation safety problems, such as the judgment of radiation dose leakage and the planning of construction path. The system includes three modules, which are the overall dose rate distribution display of multiple power plants, the dose view of a specific equipment in power plants, and the dynamic evolution of nuclear radiation leakage. The analysis and user feedbacks of the experimental results show that this interactive visualization system can present the nuclear dose distribution of power plant in real time and from different granularities. This system utilizes the color mapping schema that as the dose density increases, the color changes from green to red, which is in line with human visual perception. Meanwhile, the dynamic radiation leakage scenario view is assistant to the design of nuclear radiation protection.

由于化石燃料的日益枯竭，核能被广泛用作新能源。在核能和核技术的发展中，人们越来越关注核辐射防护问题。因此，先进的计算机技术成为解决核辐射安全问题的新途径。本文提出利用基于CUDA的射线投射体绘制构建交互式核辐射可视化系统，解决辐射剂量泄漏判断、施工路径规划等核​​辐射安全问题。该系统包括多个发电厂整体剂量率分布显示、发电厂特定设备剂量视图、核辐射泄漏动态演化三个模块。对实验结果的分析和用户反馈表明，该交互式可视化系统可以从不同粒度实时呈现电厂的核剂量分布。该系统利用颜色映射模式，随着剂量密度的增加，颜色从绿色变为红色，符合人类的视觉感知。同时，动态辐射泄漏场景视图是核辐射防护设计的辅助工具。
