Imaging of Radiation Accidents and Radioactive Contamination Using Scintillators

An accident in a nuclear power plant, which can be caused by an unpredictable event such as an explosion, fire, and earthquake, has severe and far-reaching consequences. Therefore, it is crucial to carefully and constantly monitor the plant and precisely detect any radiation source. Radiation contamination in laboratories and in the environment due to nuclear fallout is among the issues that require an immediate solution. Radiation detection has become increasingly important because of the increasing number of nuclear power plants that have been established to replace conventional power plants, as part of the effort to suppress carbon dioxide emission. For these purposes, this chapter will discuss the principle and method of mapping flying radiations. Visual mapping of intensity and direction of
