RADIOGRAPHIC TESTING SYSTEM AND RADIOGRAPHIC TEST METHOD USING RADIOACTIVE ISOTOPE

摘要

The present invention relates to a radiographic testing system using a radioactive isotope. The radiographic testing system using a radioactive isotope comprises: one or more gamma ray irradiators which irradiate gamma rays (γ-ray) released from a radioactive isotope toward an object: a detector which detects the gamma rays penetrating the object: and a controller which controls the irradiator using the half-life of the radioactive isotope in order to regulate the gamma rays irradiated to the object. Therefore, the radiographic testing system can improve efficiency more than the existing systems and can reduce unnecessary loss by controlling radiation irradiated to the object using the half-life of the radioactive isotope.
