The contamination in pipelines can lead to significant exposure to alpha particles, making it essential to develop reliable methods for measuring α contamination activity. Laser-Resonant Photoacoustic Detection (LRAD) is a sensitive technique used to measure α contamination activity on the inner surface of pipelines. The objective of this research is to evaluate the effectiveness of LRAD in measuring α contamination activity on the inner surface of pipelines.Methods:A pipeline will be selected for analysis and cleaning, after which it will be coated with a known α-emitting source. An LRAD system will then be used to measure the α contamination activity by detecting acoustic pressure waves generated by the α particles. The activity results obtained using the LRAD system will then be compared with the results obtained using traditional α spectroscopy.Expected Results:The research is expected to produce a method for measuring α contamination activity on the inner surface of pipelines that is more reliable and sensitive than traditional α spectroscopy. The LRAD system is anticipated to detect smaller α contamination levels, which is essential in cases where low levels of contamination exist.Conclusion:The method for measuring α contamination activity on the inner surface of pipelines using LRAD has significant potential in the field of radiological safety. The research plans to show that the LRAD system is a valuable tool in measuring α 精品文档---下载后可任意编辑contamination and potentially reducing the risks of exposure to alpha particles. The successful implementation of this method will contribute to the development of a reliable technique for evaluating α contamination on the inner surfaces of pipelines.
