ABSTRACT
In recent years, there have been many studies on the development of various plastic scintillation dosimeters (PSDs) exploiting optical fibers for measuring real-time in situ dose information in both diagnostic radiology and radiotherapy. To avoid complicated dose calibration processes during scintillation dosimetry, all dosimetric materials of a PSD system should have a tissue or water-equivalent characteristic. In this respect, the dosimeter probe of the PSD system is composed of an organic scintillator and an optical fiber, and these components have a nearly water-equivalent characteristic. Here, an optical fiber, which is made of a transparent plastic or silica glass core surrounded by a cladding material, is used as a light guide.
