Use of plastic scintillator with fiber optics for detection of radiation with high spatial resolution

摘要

The objective fo this paper is to describe a method for detecting x-ray in real time with high spatial resolution. The method uses a 1-meter glass fiber, a 2 mm plastic scintillator, and a collecting device such as photomultiplier tube to respond to the radiation field. This device can be automated for use in any industries, which uses radiation for their processes. The resolution can only be limited by the size of the detector. This plastic scintillator probe has a homogeneous sensitivity and it is water equivalent. The scintillator minimizes dose perturbation in water, and it has a emission peak around 432 nm. The reproducibility of the system has been tested, and the percent variation has been less than 3
