The plastic scintillator emits fluorescent light of which the quantity is proportional to the absorbed radiation dose in it. And it can be believed that in this phenomenon the energy dependence does not exist. Based upon the above characteristics of the plastic scintillator a new method of the integral dose measurement was developed. A cuboid plastic scintillator of 28×28×15 cm in size was used as a phantom. It was irradiated by X rays and fluorescent light from the phantom was measured as a direct current using a photomultiplier, thus the integral dose in the phantom was obtained. Our results were relatively well compatible with those obtained by Bewley and his co-workers.
