Description

방사선치료실용 차폐도어 및 그 제작방법{A shield door for radiation clinic and making method therefore}A shield door for radiation clinic and making method therefore}

본 발명은 방사선치료실용 차폐도어 및 그 제조방법에 관한 것으로, 더욱 상세하게는 방사선치료실내에서 방사되는 방사선, 특히 중성자가 방사선치료실의 입구를 통해 외부로 누출되는 것을 확실히 차폐할 수 있는 구조를 갖도록 한 방사선치료실용 차폐도어 및 그 제조방법에 관한 것이다.The present invention relates to a shielding door for a radiation treatment room and a method of manufacturing the same, and more particularly, to have a structure that can reliably shield the radiation emitted from the radiation treatment room, in particular neutron leaking to the outside through the entrance of the radiation treatment room. It relates to a shielding door for a radiation treatment room and a method of manufacturing the same.

일반적으로 방사선 동위원소는 매우 많은 분야에서 사용되고 있는데, 그 대표적인 것이 원자력발전소 및 각종 의료기기, 비파괴 검사장치 등에 사용된다.In general, radioisotopes are used in many fields, and representative ones are used in nuclear power plants, various medical devices, and non-destructive inspection devices.

이러한 원자력 발전소 및 의료기기, 비파괴 검사장치에 사용되는 방사선 동위원소에서 방사되는 각종 방사선은 인체에 매우 유해하다.Various radiations emitted from radioisotopes used in such nuclear power plants, medical devices, and non-destructive inspection devices are very harmful to the human body.

즉, 인체에 일정량이상의 방사선이 피폭되면 인체의 유전자 또는 세포가 변형을 일으키게 되어 각종 암을 유발시키게되며, 이러한 질병은 한 세대에 국한되지 않고 다음 세대까지 유전됨으로 이러한 방사선이 외부로 누출되지 않도록 하는 것이 매우 중요하며, 특히 사람들이 빈번하게 왕래하는 의료기관내의 방사선치료실의 경우에는 이러한 방사선의 완벽한 차폐가 절실히 요구되고 있다.In other words, when a certain amount of radiation is exposed to the human body, genes or cells of the human body are modified to cause various cancers. These diseases are not limited to one generation but are inherited to the next generation so that such radiation does not leak to the outside. This is very important, and especially in the case of radiation treatment rooms in medical institutions where people frequently visit, there is an urgent need for complete shielding of such radiation.

따라서, 이러한 방사선치료실의 벽체는 방사선을 완벽하게 차폐할 수 있도록 콘크리트와 납 등의 비중이 높은 물질을 사용하여 차폐구조를 형성시킴으로써 방사선이 벽체를 투과할 수는 없지만 벽체에 반사되는 방사선이 방사선치료실의 입구를 통하여 외부로 누출되어 짐으로 입구를 개폐하는 차폐도어에 대한 중요성이 날로더해지고 있는 실정이다.Therefore, the wall of such a radiation treatment room forms a shielding structure using materials with high specific gravity such as concrete and lead to completely shield the radiation, so that the radiation cannot penetrate the wall, but the radiation reflected on the wall is the radiation treatment room. The importance of the shielding door to open and close the entrance to the load leaked to the outside through the entrance of the situation is increasing day by day.

이러한 종래의 차폐도어는 철판과 연판을 적층시켜 제작되어 있다.Such a conventional shielding door is manufactured by laminating an iron plate and a soft plate.

그러나, 상기와 같은 종래의 차폐도어는 방사선 발생장치로부터 방사되는 일차방사선(α, β, γ)은 어느 정도 차폐될 수 있지만 고에너지(10Mev이상)의 발생장치에서 방사되는 방사선중 중성자선은 차폐효율이 떨어질 뿐만 아니라 그러한 중성자선을 차폐시키기 위하여 무한정 차폐도어의 두께를 두껍게 할 수 도 없다는 문제점이 있었다.However, in the conventional shielding door as described above, the primary radiations (α, β, and γ) radiated from the radiation generating apparatus may be shielded to some extent, but the neutron beam is shielded among the radiations emitted from the high energy (more than 10 Mev) generating apparatus. In addition to reducing efficiency, there is a problem in that the thickness of the shielding door can not be thickened in order to shield such neutron beams.

따라서, 본 발명은 상기와 같은 종래의 문제점을 고려하여 안출한 것으로써, 그 목적은 방사선치료실내에서 방사되는 방사선, 특히 중성자선이 방사선치료실의 입구를 통해 외부로 누출되는 것을 확실히 차폐하기 위한 방사선치료실용 차폐도어를 제공하는 것이다.Accordingly, the present invention has been made in view of the above-described conventional problems, and an object thereof is to provide a radiation for reliably shielding radiation emitted from the radiation treatment chamber, in particular, neutron radiation leaking out through the entrance of the radiation treatment chamber. To provide a shielding door for the treatment room.

또한, 본 발명의 다른 목적은 방사선치료실내에서 방사되는 방사선, 특히 중성자선에 의하여 이차적으로 발생되는 방사선이 방사선치료실의 입구를 통해 외부로 누출되는 것을 확실히 차폐하기 위한 방사선치료실용 차폐도어의 제작방법을 제공하는 것이다.In addition, another object of the present invention is a method of manufacturing a shielding door for a radiation treatment room for reliably shielding the radiation emitted from the radiation treatment room, in particular the secondary radiation caused by neutron radiation to the outside through the entrance of the radiation treatment room.
