Title: CONTAINMENT DEVICE FOR SHIELDING X-RAYS RADIATED FROM X-RAY TUBE
Abstract:
The present invention relates to a "containment device for shielding X-rays radiated from an X-ray tube," which efficiently shields X-rays radiated from an X-ray tube used in a static eliminator, thereby avoiding risk factors against a human body due to the external leakage of radiation, and which satisfies [radiation leakage of 1 μSv/h or less], which is defined as a full containment condition in the "standards for design approval and inspection of radiation devices" prescribed by the Nuclear Safety and Security Commission, thereby resolving the inconvenience in terms of report and obligation according to the legal regulations under Atomic Energy Act related to radiation generating devices. To this end, the present invention is configured such that when high voltage supplied from a high voltage generator is supplied through a wire connected to a wire of the X-ray tube, X-rays are radiated from an X-ray radiation unit of the X-ray tube, and the radiated X-rays are discharged in a manner that anions and cations ionized within a containment unit are discharged via an air outlet of a nozzle along the flow of compressed air so as to eliminate static electricity of an electrified body whereby the X-rays radiated from the X-ray radiation unit of the X-ray tube are primarily shielded by a shielding plate of the containment unit, and the X-rays can be secondarily shielded by a circular closing plate of the nozzle even if a part of the X-rays leaks via a circular arc opening formed at the edge of the shielding plate of the containment unit.
