After the incident, airport security is much higher and stricter than ever before. Even though you are not American citizens, you may remember the terrorism of the 9.11. On the other hand, do you know the terrorism by AUM Shinrikyo, on the Tokyo Metropolitan Subway in 1995? In our society, this was the first terrorism, which was used a chemical weapon, sarin gas, to the general public. When AUM Shinrikyo members attacked subways, Japanese People were in panic. However, this attack was occurred over 15 years ago, so even Japanese people become forgetting it. This is because the Japanese people have never experienced such terrible terrorism since 1995. On the other hand, one of current global issues is how to handle global terrorism. Today, terrorists try to attack our society by any means. As a last resort, they are able to use CBRN (chemical, biological, radiological, nuclear) weapons of mass destruction if they would like to. "If our society is attacked by these weapons…" We must consider of the worst thing and be ready for any situation against terrorism. This paper discusses how the society prepares for CBRN terrorism. As an example of terrorist attacks by CBRN weapons, “1995 Tokyo Sarin Gas Attack” is explained. The attack aimed to Tokyo Metropolitan Subway system, so it has much information for transportation security management and is instructive for security and safety. In this paper, I also focus on detection equipments in airport security system. Current hot topic on airport security is how to detect explosives. In near future, however, we will need to discuss on CBRN terrorism against airports. This paper may be effective for the next era of our social security management.}, publisher = {Society for Social Management Systems}, title = {Study on Security Management Against Weapons of Mass Destruction}, volume = {6}, year = {2010} }
