Description

휴대용 방사선측정기Portable radiometer
본 발명은 휴대용 방사선측정기에 관한 것으로, 보다 상세하게는 The present invention relates to a portable radiometer, more specifically
방사선원으로부터 방출되는 방사선(α선, β선, γ선)을 검출하기 위한 휴대용 방사선측정기로써, 사용자가 사용현장에서 손쉽게 조작하여 사용할 수 있으며, 경제성을 높여 단순화 소형화 하면서도 정밀한 검출을 할 수 있는 간편한 휴대용 방사선측정기에 관한 것이다.As a portable radiometer for detecting radiation (α-ray, β-ray, γ-ray) emitted from a radiation source, the user can easily operate and use it at the site of operation, and it is simple and portable, which can simplify and miniaturize precisely by increasing economic efficiency. It relates to a radiometer.
통상 방사선은 α선, β선, γ선 세 가지이다. 하지만 일반적으로 방사선이라고 할 때는 이 세 가지뿐만 x선, 중성자선과 같은 다른 입자나 전자기파를 합쳐서 언급하는 경우가 많다. 방사선에 공통인 성질로서는 이온화작용, 사진작용, 형광작용 등이 있다. 여기서 방사선은 물질과의 작용으로 물질에 이온화작용을 일으키고, 그 에너지를 잃게 되는 것이다. 방사선 이용의 확대에 따르는 방사성 물질에 의한 환경오염 및 이로 인해 유발되는 방사선 장해 및 방사선의 피폭으로 인한 인체장해 등이 중요한 사회문제가 되고 있다.There are three types of radiation, α-ray, β-ray and γ-ray. In general, however, these three types of radiation are often referred to as a combination of other particles or electromagnetic waves such as x-rays and neutron beams. Properties common to radiation include ionization, photography, and fluorescence. The radiation here causes the material to ionize and lose its energy. The environmental pollution caused by radioactive materials and the human body caused by the radiation exposure caused by the radioactive material due to the expansion of the use of radiation has become an important social problem.
방사선은 α선, β선, 중성자선과 같이 운동하는 입자인 입자선과 γ선, x선과 같은 전자기파로 나뉘며, 입자선인 α선, β선은 운동에너지가 매우 쉽게 감소하여 종이 정도의 물질에도 쉽게 차폐되며, 반면 전자기파인 γ선, x선은 투과력이 강해 10cm 정도 이상의 납에서 차폐되는 것이다.Radiation is divided into particle rays, which are particles that move like α rays, β rays, and neutron rays, and electromagnetic waves such as γ rays and x rays. Particle rays, α rays and β rays, are easily reduced in kinetic energy and are therefore easily shielded by paper-like materials. On the other hand, γ-rays and x-rays, which are electromagnetic waves, have strong penetrating power and are shielded from lead of about 10 cm or more.

종래의 이동식 방사능 측정장치의 경우 그 기술적 구성이 복잡하고 어렵게 되고 입자선인 α선, β선의 방사선량을 측정하기 위해서는 방사능 측정기를 사용하였으며, 전자기파인 γ선, x선의 방사선량을 측정하기 위해서는 방사선 측정기를 각각 사용함으로 각각의 방사선량을 측정 시 번거로운 문제점이 있었으며, 형태가 크고 고가의 제품이 다수여서 보관이 용이하지 않는 문제점이 있었다.In the case of the conventional mobile radioactivity measuring device, the technical configuration is complicated and difficult, and the radioactivity measuring device is used to measure the radiation dose of α rays and β rays, which are particle beams, and the radiation measuring instrument is used to measure radiation doses of γ rays and x rays, which are electromagnetic waves There was a problem in measuring the amount of radiation by using each, and there is a problem in that it is not easy to store because there are a large number of expensive products.
또한, 방사선을 검출하고 측정하기 위해 이온화작용을 이용하는 전기적인 측정기, 방사선의 형광작용을 이용하는 신틸레이션 계수기 및 방사선의 사진유제(寫眞乳劑)에 대한 감광작용을 이용하는 사진건판 등 각종 방법이 이용되고 있다.In addition, various methods such as an electrical measuring device using ionization to detect and measure radiation, a scintillation counter using fluorescence of radiation, and a photographic plate using a photosensitive action of radiation are used.

상기 방법 중 전기적인 측정기로는 옛날부터 여러 가지 형식의 이온화상자, 가이거-뮐러 계수기 등 기체의 이온화작용을 이용하는 것이 사용된다.Among the above methods, as an electrical measuring instrument, various types of ionization boxes, such as Geiger-Müller counters, are used.
상기 이온화상자는 방사선에 의해서 기체 내에 생기는 이온을 전극에 모아서 전극전위의 변화를 측정하여 통과한 방사선의 강도를 측정하는 장치이고, 가이거-뮐러 계수기는 기체의 이온화작용에 의해서 방전관 내에 발생한 방전을 펄스로서 도출하고, 이것을 증폭하여 방사선 입자의 수를 세는 장치이다.The ionization box is a device for collecting the ions generated in the gas by the radiation to the electrode to measure the intensity of the radiation passed by measuring the change in electrode potential, Geiger-Müller counter pulses the discharge generated in the discharge tube by the ionization of the gas It is a device which derives and amplifies this and counts the number of radiation particles.
여기서 가이거-뮐러 계수기를 이용한 측정 장치의 경우에 있어서, 측정기의 동작 상태를 점검하기 위하여 기준 방사선원을 별도로 가지고 다니면서 외부에서 가이거-뮐러 계수기에 접근시켜 점검을 하였다. 그러나 이러한 방식은 방사선원을 분실할 우려가 있고, 가이거-뮐러 계수기와의 정확한 거리를 유지시키기 어려워 측정치의 정확도가 떨어지는 문제점이 있다.Here, in the case of the measuring device using a Geiger-Müller counter, the inspection was performed by approaching the Geiger-Müller counter from the outside while carrying a separate reference radiation source to check the operation state of the measuring device. However, this method has a problem in that the radiation source is lost, and it is difficult to maintain an accurate distance from the Geiger-Müller counter, thereby lowering the accuracy of the measurement.
관련 기술을 살펴보면 출원번호 10-2006-0099536은 휴대용 단말기에 방사선 검출기를 구성한다는 기술로 반도체검출기를 이용한 방사선 검출장치를 휴대단말기에 일체화 시켜서 방사선의 피폭량을 측정할 수 있고 기준치를 설정하여 기준치를 초과한 방사선이 검출 되었을 때 경보를 울려주는 장치에 대한 것이다.Looking at the related technology, the application number 10-2006-0099536 is a technology that configures a radiation detector in a portable terminal. The radiation detection device using a semiconductor detector can be integrated into a portable terminal to measure the exposure dose of the radiation, and the reference value is set to exceed the reference value. It is about a device that sounds an alarm when a radiation is detected.
그러나 상기의 기술을 방사선 검출과정상의 관계가 명확하게 구현되어 있지 않음으로 기술적으로 검출장치가 휴대폰에 결합되어 사용될 수 있을지 불명확하여 실현이 사실상 어렵고,However, since the relationship between the radiation detection process and the above technology is not clearly implemented, it is not clear whether the detection device can be used in combination with a mobile phone.
국제공개번호 WO 2004/013655는 방사능 물질의 검출을 위한 장치로 전자석 방사능을 전송하도록 작동적으로 배열된 전송기와, 전자석 방사능의 강도를 측정하기 위해 작동적으로 배열된 수신기 그리고 상기 강도 측정에 근거해서 상기 방사능 물질의 존재를 결정하기위해 작동적으로 배열된 처리수단으로 구성된 기술로서 해당 물체에 검출은 가능하나 대기중의 발생되고 있는 방사능의 정밀한 검출은 어려운 것이다.International Publication No. WO 2004/013655 relates to a transmitter operatively arranged to transmit electromagnetic radiation to a device for the detection of radioactive material, a receiver operatively arranged to measure the intensity of electromagnetic radiation and to the strength measurement It is a technique consisting of processing means arranged operatively to determine the presence of the radioactive material, which can be detected on the object, but it is difficult to accurately detect the generated radiation in the atmosphere.
