An Study on Radiation Application and Public Safety

방사선이용과 공공안전

Radiation technologies are being utilized in a wide range of daily modern life and provide the public with valuable benefits through applications in fields of medical, industrial, agricultural, and science & engineering research. On the other hand, there is a high possibility that radioactive materials can be used for malevolent purposes such as dirty bombs. The International community, therefore, has made efforts to improve the security of radioactive sources aimed at protecting the public from radiological terrorism. The paper investigated high-risk radioactive sources which could be used as dirty bombs. The paper reviewed the possibility of radiological weapon attacks and analyzed international trends to enhance security of radioactive sources. This study also proposed our countermeasures to reduce the threat of radiological terrorism and to properly respond to the radiological emergency caused by the radiological weapon attack.
