Abstract

Abstract Radioisotope applications in industrial process inspection and evaluation using gamma-ray emitters provide otherwise unavailable information. Offering alternative gamma-ray sources can support the technology by complementing sources’ availability and radiation safety. This work proposes to replace gamma-ray from radioisotopes with prompt gamma-ray from the interaction of neutrons with stable isotopes injected into the industrial process or with the structural material of the industrial process equipment. Monte Carlo N-Particle Transport Code (MCNP5) was used to simulate the irradiation of two-phase flow pipes by 252Cf neutron source. Two simulations were run for each pipe, with and without mixing the liquid phase with the stable isotope 157Gd. The detected gamma-ray spectra were analysed, and images of the two phases inside the pipes were produced. The images were compared to images obtained from simulations of gamma transmission measurement using 60Co. Furthermore, results for prompt gamma computed tomography (CT) were presented and discussed. The studies’ outcomes indicate the potential of prompt gamma-ray to carry out the sealed sources applications of gamma transmission measurements and imaging.

工业过程评价的快速伽马射线方法：模拟研究

摘要放射性同位素在使用伽马射线发射器的工业过程检查和评估中的应用提供了其他方面无法获得的信息。提供替代伽马射线源可以通过补充源的可用性和辐射安全性来支持该技术。这项工作提出用中子与注入工业过程中的稳定同位素或与工业过程设备的结构材料相互作用产生的瞬发伽马射线代替放射性同位素产生的伽马射线。采用蒙特卡罗N粒子输运程序（MCNP5）模拟了252Cf中子源对两相流管道的辐照。在液相与稳定同位素157Gd混合和不混合的情况下，对每条管道进行了两次模拟。对探测到的伽马射线光谱进行了分析，并生成了管道内两相的图像。将这些图像与从使用60Co的伽马透射测量的模拟中获得的图像进行比较。此外，还介绍并讨论了即时伽马计算机断层扫描（CT）的结果。研究结果表明，即时伽马射线有可能在伽马透射测量和成像的密封源应用中发挥作用。
