PURPOSE: A radioactivity measuring device using a dielectric resonator and a radioactivity measuring method are provided to form the radioactivity measuring device with parts, which are relatively cheap, by adopting the dielectric resonator and to measure radioactivity without an energy loss. CONSTITUTION: A radioactivity measuring device using a dielectric resonator comprises a source unit(10), a sensor unit(20), and a processing unit(30). The source unit generates the electromagnetic energy of predetermined frequencies. The sensor unit receives the electromagnetic energy, radiates the same to an object, and detects electric waves reflected by the object. The processing unit determines a resonant frequency of the sensor unit by controlling the source unit and detects the radioactivity of the object based on changes in the resonant frequency and the reflectivity of the detected electric waves. The sensor unit includes the dielectric resonator. [Reference numerals] (0) Object to be measured; (10) Source unit; (20) Sensor unit; (30) Processing unit; (40) Display unit; |
