Abstract
Description
Technical Field
[0001] This application relates to the field of nuclear energy science and engineering technology, and in particular to a method and system for determining the risk level of radiation work based on quantitative analysis. Background Technology
[0002] Nuclear power plant workers face confirmed or potential risks of ionizing radiation exposure in practice. Before engaging in radioactive work, it is essential to fully identify and analyze the potential radiation risks. Radiation risk assessment is a crucial aspect of radiation protection, but it is primarily limited to qualitative analysis and cannot be quantified. This is because radiation work risks are dynamically changing. Any weaknesses in a nuclear power plant's management expectations, work planning and implementation, risk identification and judgment, supervision, monitoring, and personnel attitudes can lead to misjudgments of radiation work risks, resulting in the failure of corresponding radiation protection measures. Therefore, there is an urgent need to provide a quantitative, scientific, accurate, and reliable method for determining the level of radiation work risks. Summary of the Invention
