摘要

我们利用富铝磷酸盐玻璃开发出了一种紧凑、方便的剂量计装置，它是一种方便的剂量分布分析工具。通过额外添加 0.2 摩尔% 的铝杂质，对磷酸盐玻璃的成分进行了改良，从而使磷酸盐玻璃能够在包括 X 射线在内的各种辐射照射下用作实时闪烁体，并发出宽带辐射光，而不会产生大的积聚效应。通过使用富铝磷酸盐玻璃珠，在亚毫米尺度上实现了实时辐射监测。离子束分析证实，富铝磷酸盐玻璃不含任何重元素。基于富铝磷酸盐玻璃的光导纤维剂量测定得到了证实，并在 X 射线照射下观察到了稳定的放射性发光。

Convenient real-time radiation monitoring and measurement device using phosphate glass with aluminum impurities

A compact, convenient dosimeter device for a convenient dose-distribution profiling tool were developed using aluminum-enriched phosphate glass. The composition of the phosphate glass were modified by adding an additional 0.2 mol % aluminum impurity, which allowed the phosphate glass to be used as a real-time scintillator with broadband radioluminescence under various types of radiation exposure, including X-rays, without large build-up effects. Real-time radiation monitoring was accomplished on a submillimeter scale by using aluminum-enriched phosphate glass beads. Ion beam analysis confirmed that the aluminum-enriched phosphate glass contained no heavy elements. Optical fiber dosimetry based on the aluminum-enriched phosphate glass was demonstrated, and stable radioluminescence was visualized under X-ray irradiation.

期刊介绍： Section B of Nuclear Instruments and Methods in Physics Research covers all aspects of the interaction of energetic beams with atoms, molecules and aggregate forms of matter. This includes ion beam analysis and ion beam modification of materials as well as basic data of importance for these studies. Topics of general interest include: atomic collisions in solids, particle channelling, all aspects of collision cascades, the modification of materials by energetic beams, ion implantation, irradiation - induced changes in materials, the physics and chemistry of beam interactions and the analysis of materials by all forms of energetic radiation. Modification by ion, laser and electron beams for the study of electronic materials, metals, ceramics, insulators, polymers and other important and new materials systems are included. Related studies, such as the application of ion beam analysis to biological, archaeological and geological samples as well as applications to solve problems in planetary science are also welcome. Energetic beams of interest include atomic and molecular ions, neutrons, positrons and muons, plasmas directed at surfaces, electron and photon beams, including laser treated surfaces and studies of solids by photon radiation from rotating anodes, synchrotrons, etc. In addition, the interaction between various forms of radiation and radiation-induced deposition processes are relevant.
