| 摘要 |
A device in form of a practical and reusable card for personal monitoring of incident penetrating radiation energy and for reading said energy comprising a stimulable phosphor absorbing and storing said energy and being stimulable with a wavelength lambdaa; an electroluminescent phosphor emitting, upon application of an electrical field, stimulation light with wavelength lambdaa, said wavelength lambdaa being different from the said incident penetrating radiation, and wherein said device is equipped with means in order to apply an electrical field on said electroluminescent phosphor and wherein said stimulable phosphor and said electroluminescent phosphor are positioned relative to each other so that said light emitted by said electroluminescent phosphor reaches said stimulable phosphor for stimulating said phosphor in order to release stimulated light.
