摘要

在诊断和治疗过程中,为剂量测定和优化乌克兰居民的医疗照射(以及对紧急情况进行剂量测定控制和监测的可能性)建立一个有科学依据的质量保证系统属于电离辐射源(IRs)应用领域。包括乌克兰在内的大多数国家的现代医学趋势证明,医疗照射的比例在持续增加。国际辐射防护委员会(ICRP)、国际原子能机构(IAEA)、世界卫生组织(WHO)和欧盟委员会(EC)等国际组织的文件中规定了将电离辐射源用于医疗目的并确保患者辐射安全的主要要求和建议。 确保放射治疗质量的关键因素之一是计量和剂量测定支持。为了提高放射治疗的效果,减少未来并发症的数量,有必要对患者体内的局部目标进行照射,剂量误差不得超过 5%。控制治疗设备的辐射输出,即校准治疗过程中使用的治疗光束,是放射治疗的基本要素。 辐射防护计划的基础是使用热释光剂量计(TLDs)检查远程放射治疗设备校准的准确性,热释光剂量计是一种装有热释光粉末的小塑料胶囊,通过邮局寄往放射中心,在水模型中接受特定剂量的照射。 乌克兰的放射治疗主要使用钴机、X 射线治疗设备和直线加速器。 研究结果包括使用自动阅读器 PCL-3 检验测量结果对各种照射参数的依赖性,确定热释光粉 TLD-100 的剂量学特性,以及在远程伽马治疗设备的标准照射条件下开发热释光剂量计的校准方法。 因此,研究使用热释光剂量计进行射束校准的准确性,可以及时发现临床剂量测定中的误差,减少患者在治疗过程中出现与辐射相关的并发症。

Experimental study of dosimetric properties of thermoluminescent powder TLD-100
The creation of a scientifically substantiated quality assurance system for dosimetry and the optimization of medical exposure of the population of Ukraine during diagnostic and therapeutic procedures (and the possibility of dosimetric control and monitoring of emergency situations) falls within the field of the application of ionizing radiation sources (IRs). Trends in modern medicine in most countries, including Ukraine, prove a continued increase in the share of medical exposure. The main requirements and recommendations for the use of IRs for medical purposes while ensuring the radiation safety requirements for patients are provided in the documents of such International Organizations as the International Commission on Radiological Protection (ICRP), the International Atomic Energy Agency (IAEA), the World Health Organization (WHO) and the European Commission (EC). One of the key factors to ensure the quality of radiation therapy is metrological and dosimetric support. To enhance the effectiveness of radiation treatment and reduce the number of complications in the future, it is necessary to irradiate the local target within the patient’s body with a dose error of no more than 5%. Control of the radiation output of the therapeutic device, i.e., the calibration of the therapeutic beam used in the treatment process, is an essential element of radiation therapy. Radiation protection programmes are based on checking the accuracy of the calibration of remote radiotherapy devices using thermoluminescent dosimeters (TLDs) – small plastic capsules filled with thermoluminescent powder that are sent by post to radiology centres for exposure to a specific dose in a water phantom. Radiation therapy in Ukraine is primarily conducted using cobalt machines, X-ray therapy devices and linear accelerators. The results of the study include the examination of the dependency of measurement results on various exposure parameters using the automatic reader PCL-3, the determination of dosimetric characteristics of the thermoluminescent powder TLD-100, and the development of a calibration method for thermoluminescent dosimeters under standard irradiation conditions on a remote gamma therapy device. Therefore, the accuracy of beam calibration using TLD dosimeters has been studied, which will enable to timely detect errors in clinical dosimetry and reduce the number of cases of radiation-related complications for patients during their treatment.
