Abstract

With the continued increase in the number of pieces of diagnostic medical radiography equipment being used, radiation shielding in radiology departments is becoming increasingly important. Lead is the most commonly used material for radiation protection; however, there are numerous disadvantages associated with the use of lead, including environmental hazards and harm to the human body. Alternative shielding materials that can be used as replacements include barium sulfate, tungsten, or bismuth. Among alternative materials, barium sulfate appears to be the most cost-effective and easiest to process. In the present study, before constructing shielding barriers, a barrier thickness program for lead-free barrier materials based on National Council on Radiation Protection and Measurements (NCRP) Report No. 147 was used to determine the appropriate barrier thickness. The required thickness for lead-free boards for each type of diagnostic radiography room was calculated based on a tertiary general hospital in the Republic of Korea.

评估放射诊断中辐射屏蔽的无铅替代品：韩国一家三级综合医院的案例研究。

随着医疗放射诊断设备使用数量的不断增加，放射科的辐射防护变得越来越重要。铅是最常用的辐射防护材料，但铅的使用有许多缺点，包括对环境的危害和对人体的伤害。可替代的屏蔽材料包括硫酸钡、钨或铋。在替代材料中，硫酸钡似乎最具成本效益，也最容易加工。在本研究中，在建造屏蔽屏障之前，根据美国国家辐射防护和测量委员会（NCRP）第 147 号报告，采用了无铅屏障材料的屏障厚度方案，以确定适当的屏障厚度。根据大韩民国一家三级综合医院的情况，计算出了各类放射诊断室所需的无铅板厚度。

期刊介绍： Radiation Protection Dosimetry covers all aspects of personal and environmental dosimetry and monitoring, for both ionising and non-ionising radiations. This includes biological aspects, physical concepts, biophysical dosimetry, external and internal personal dosimetry and monitoring, environmental and workplace monitoring, accident dosimetry, and dosimetry related to the protection of patients. Particular emphasis is placed on papers covering the fundamentals of dosimetry; units, radiation quantities and conversion factors. Papers covering archaeological dating are included only if the fundamental measurement method or technique, such as thermoluminescence, has direct application to personal dosimetry measurements. Papers covering the dosimetric aspects of radon or other naturally occurring radioactive materials and low level radiation are included. Animal experiments and ecological sample measurements are not included unless there is a significant relevant content reason.
