본 발명은 방사선 투과 검사장치에 적용되는 선원 전송관에 관한 것으로서, 보다 상세하게는, 피검사체의 내부 결함에 대한 정보를 측정하기 위한 방사선 투과 검사 공정에서 발생할 수 있는 기기 작동오류로 인한 피폭사고를 감소시킬 수 있는 방사선 안전을 위한 누드형 선원 전송관에 관한 것이다.The present invention relates to a source transmission tube applied to a radiographic inspection apparatus, and more particularly, to an exposure accident due to a device operation error that may occur in a radiographic inspection process for measuring information about an internal defect of an inspected object. It relates to a nude source transmission line for radiation safety that can be reduced.
일반적으로 비파괴 검사는 발전소 건설 현장이나 배관공사 및 압력용기 등을 제작하는 다양한 산업현장에서 용접상태 등의 내부 결함유무를 측정하는 데 매우 유용하게 적용되고 있으며, 또한 피검사체에 손상을 가하지 않고 검사할 수 있어 제품의 안정성 및 신뢰성 향상에 크게 기여하고 있다.In general, non-destructive testing is very useful for measuring the presence of internal defects such as welding conditions in power plant construction sites, plumbing works and pressure vessels. It greatly contributes to improving the stability and reliability of the product.
이러한 비파괴 검사 방식의 하나인 방사선 투과검사는 방사선을 이용하여 피검사체를 투과 촬영하여 얻은 필름을 현상하여 판독하므로서 재료 및 기기에서의 내부 구조재질의 불연속한 위치를 검출하는 방법이다.One of the non-destructive inspection methods, the radiographic inspection is a method of detecting discontinuous positions of materials and internal structural materials in a device by developing and reading a film obtained by radiographically inspecting an inspected object.
여기서, 비파괴 검사시에 이용되어지는 방사선으로는 X선과 감마선이 산업현장에서 주로 사용되어지고 있고, 현장 용접에 대해서는 이동성과 적합성 때문에 90% 이상이 감마선을 이용한 방사선 투과 검사가 수행된다.Here, X-rays and gamma rays are mainly used in industrial sites as radiation used for non-destructive inspection, and in the field welding, more than 90% of radiographic examinations using gamma rays are performed because of mobility and suitability.
비파괴 검사에서 감마선을 이용한 방사선 투과 검사는 작업자가 방사선 취급과 관련하여 안전 관리 부주위로 인한 방사선 피폭 등의 방사선 사고의 위험성이 있다. 비파괴 분야에서 발생하는 방사선 사고는 한가지 원인에 의해 발생되는 것이 아니며 여러 원인이 복합되어 발생하는 데, 대체로 안전관리 미비, 작업자의 실수, 장치 결함 등의 물적, 인적 요인에 의한 피폭사고가 주를 이루고 있다.In non-destructive testing, radiographic examination using gamma rays presents the risk of radiation accidents such as radiation exposure due to the inadequate safety management by workers. Radiation accidents in non-destructive fields are not caused by a single cause, but are caused by a combination of causes. In general, exposures due to physical and human factors such as inadequate safety management, human error, and device defects have.
방사선 사고를 줄이기 위하여 개인 방호 장비의 착용, 작업자의 교육 훈련을 통해 방사선 사고로 이행되는 것을 막고 있으나 감마선을 이용한 방사선 투과 검사에서 발생하는 방사선 촬영 후의 선원 회수 미확인으로 인한 사고를 근본적으로 해 결해 주지 못하였다.In order to reduce radiation accidents, personal protective equipment is worn and workers' education and training are prevented from transitioning to radiation accidents.However, it is not possible to fundamentally solve the accidents due to the unconfirmed source recovery after radiography generated by gamma ray irradiation. It was.

본 발명은 방사선 투과 검사에서 선원 상태 미확인으로 발생하는 방사선 피폭사고를 방지하고자 창출한 것으로서, 감마선을 이용한 방사선 투과 검사 작업과정에서 발생할 수 있는 작업순서의 무시, 선원과 케이블의 접촉불량 및 단선, 선원의 전송관 내에서의 전송불량 등으로 인한 방사선 피폭을 방지할 수 있는 방사선 안전을 위한 누드형 선원 전송관을 제공하는 데 기술적 과제가 있다.The present invention was created to prevent radiation exposure accidents caused by unidentified source status in radiographic examination, ignoring the operation sequence that may occur during the radiographic inspection process using gamma rays, poor contact and disconnection between source and cable, source There is a technical problem to provide a nude source transmission pipe for radiation safety that can prevent radiation exposure due to poor transmission in the transmission pipe.

본 발명의 바람직한 일실시예에 대하여 상술하였으나 본 발명의 기술적 사상 을 이탈함이 없이 다양한 실시예를 구현할 수 있음은 당업자에게는 자명하다. 예컨대, 선원 전송관을 고무 재질 이외에도 검사자가 선원을 식별할 수 있고 선원의 전송이 용이한 투명 또는 반투명의 유연한 합성 수지 재질로 구성할 수도 있다.Although a preferred embodiment of the present invention has been described above, it will be apparent to those skilled in the art that various embodiments may be implemented without departing from the spirit of the present invention. For example, in addition to the rubber material, the source transmission pipe may be made of a transparent or translucent flexible synthetic resin material that allows the inspector to identify the source and easily transmits the source.
상술한 바와 같이 본 발명에 의하면, 감마 방사선 투과 검사 장치에 장착되는 선원전송관을 투명 또는 반투명한 재질을 적용함으로써 검사 후에 작업자가 선원전송관에 있는 선원의 존재 유무를 검사자가 육안으로 용이하게 확인이 가능하여 선원을 컨테이너로 완전히 회수하여 방사선을 차폐시킬 수 있으므로 선원을 부주위로 인해 전송관내에 방치하여 방사선에 노출될 가능성을 차단함으로써 검사자 및 일반인에 대한 방사선 사고에 대한 안전성과 신뢰성을 제고할 수 있다.As described above, according to the present invention, after the inspection by the transparent or semi-transparent material applied to the source transmission tube mounted on the gamma radiographic inspection apparatus, the operator easily checks the presence of the source in the source transmission tube with the naked eye. It is possible to shield the radiation by completely recovering the source to the container, so that it is possible to enhance the safety and reliability of radiation accidents for the inspector and the public by blocking the possibility of exposure to radiation by leaving the source in the transmission pipe due to subsidiary surroundings. have.
