摘要

在这项研究中，果糖被用作剂量计，ESR 检验了辐射剂量对剂量计特性的影响。在剂量为 1、5 和 10 kGy 时进行了微波功率、g 值和响应衰减测试。结果表明，果糖在剂量为 5 × 10-2-30 kGy 时具有线性。在整个剂量范围内，果糖的辐射检测灵敏度优于蔗糖，但低于丙氨酸。辐照剂量影响微波对 ESR 强度的饱和度，在 5 和 10 kGy 时出现。辐照果糖的微波功率在 1.00 至 2.46 mW 之间。ESR 信号强度随着辐射剂量的增加而增加，这主要是由于形成了更多的自由基。此外，辐射剂量越高，果糖剂量计的响应衰减越快。与丙氨酸和蔗糖相比，在 1、5 和 10 kGy 下，果糖 ESR 强度的稳定性分别为丙氨酸 > 蔗糖 > 果糖、丙氨酸 > 果糖 > 蔗糖和丙氨酸 > 果糖 ≈ 蔗糖。

ESR spectroscopic analysis of fructose as a dosimeter for gamma radiation

In this research, fructose was used as a dosimeter, and ESR examined the influence of radiation dose on the dosimeter’s properties. Microwave power, g-value, and decay of response tests were carried out at doses of 1, 5, and 10 kGy. The results show that fructose possesses linearity at doses of 5 × 10⁻²–30 kGy. The radiation detection sensitivity of fructose is better than sucrose’s but less than alanine’s over the entire dose range. The irradiation dose influences microwave saturation on ESR intensity, occurring at 5 and 10 kGy. The microwave power for irradiated fructose ranges from 1.00 to 2.46 mW. The ESR signal intensity increases with higher radiation doses, primarily due to the formation of more free radicals. Additionally, higher radiation doses lead to faster decay of the fructose dosimeter’s response. The fructose ESR intensity stability compared to alanine and sucrose at 1, 5, and 10 kGy are alanine > sucrose > fructose, alanine > fructose > sucrose, and alanine > fructose ≈ sucrose, respectively.

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.
