摘要:	近年來由於電子通訊科技的進步，各類通訊、電子設備及產品廣泛的應用，使我們的生活環境中充滿了電磁波，電磁波所造成的環境汙染越來越嚴重，除了影響人體，也影響電子器材。為了避免電子器材受到電磁波的影響而損壞，以及人體在生理或是心理方面受到電磁波的影響，如何屏蔽電磁波已是一項重要的研究課題。除了電磁波問題外，為了更有效的電力供給，選擇利用核能來發電，但是核能發電會產生核輻射對人體造成嚴重的傷害，最近因福島核電廠的事件，核輻射汙染蔓延，如何避免核輻射汙染已經是刻不容緩的重要議題。目前對於電磁屏蔽的研究非常多，常用於屏蔽電磁波的方法及材料有利用金屬、導電性高分子、導電性複合材料及導電性表面處理。本研究將利用導電混凝土材料來提高混凝土之屏蔽性能，利用加入鋼纖維、石墨以及鐵氧體之混凝土來屏蔽高頻率及低頻率電磁波，並嘗試利用屏蔽電磁波之方法來屏蔽電磁波型式之γ射線和X射線，測試不同的配比對高、低頻電磁波及γ射線和X射線的屏蔽效益，期望能加強甚至取代目前所使用的一般混凝土或重質混凝土屏蔽體，研究出具有電磁屏蔽甚至核輻射屏蔽功能之導電混凝土，並了解不同配比下所製作的導電混凝土試體，其對於導電混凝土之導電性及屏蔽效果有何影響。導電混凝土在屏蔽電磁輻射的研究在國外已取得良好的發展，本研究將在此基礎上更進一步，並探討屏蔽輻射線的可行性。 In recent years, as advances in electronic communication technology, various types of communications, electronic equipment and products widely used, let our living environment full of electromagnetic waves, electromagnetic waves caused by environmental pollution is getting worse, not only affect the human body, but also affect electronic equipment. In order to avoid the impact of electronic equipment damaged by the waves, and the people were in the physiological or psychological effects of electromagnetic waves, how to shield electromagnetic waves is an important research topic. In addition to electromagnetic problems, in order to more efficient power supply, the option of using nuclear power to generate electric power, but nuclear power will produce nuclear radiation causing serious harm on the human body, the recent events in Fukushima nuclear power plant, radioactive contamination spread, how to avoid nuclear radiation is an urgent agenda. At present, there were many study of electromagnetic shielding, commonly used in electromagnetic shielding methods and materials are using metal, conductive polymer, conductive composites and conductive surface. This study will use the conductive concrete to improve the shielding properties of concrete, adding steel fiber, graphite and ferrite into concrete to shield the high-frequency and low frequency electromagnetic waves, and attempts to use the method of shielding electromagnetic wave to shield γ-rays and X-rays which are electromagnetic waves type , test the shielding effectiveness of different proportion for high and low frequency electromagnetic waves and X-ray and γ-ray, hoping to enhance or even replace the current general concrete or heavy concrete shelter, Developed the conductive concrete with the ability of electromagnetic shielding and radiation shielding, and understand producing conductive concrete specimens by using different proportion, how affect the conductivity and shielding effectiveness of the concrete.
