Description

감마분광분석기용 완전 밀폐형 시료 용기Fully sealed sample container for gamma spectroscopy
본 발명은 감마분광분석기용 완전 밀폐형 시료 용기에 관한 것이다. 자세하게, 본 발명은 방사능을 측정하고자 하는 시료를 담는 하우징과 하우징에 유입된 시료를 외부와 차단하는 덮개를 구비하고 상기 하우징과 상기 덮개를 시밍(seaming)하여 시료의 외부 유출을 완전 차단시키는, 감마분광분석기용 완전 밀폐형 시료 용기에 관한 것이다.The present invention relates to a hermetically sealed sample container for a gamma spectrometer. In detail, the present invention includes a housing containing a sample to be measured for radioactivity and a cover for blocking a sample introduced into the housing from the outside, and seaming the housing and the cover to completely block external leakage of the sample. A fully sealed sample container for a spectrometer.
일반적으로, 방사능 측정 성능 시험에 있어서 도 1에 도시된 것과 같이 시료가 위치되는 하부 하우징(10)과, 하우징(10)에 위치된 시료를 외부와 1차적으로 격리 시키는 제1 덮개(20), 및 제1 덮개(20)와 외부를 2차적으로 격리 시키는 제2 덮개(30)로 구성된 마리넬리 비이커가 널리 이용되고 있다.In general, in the radioactivity measurement performance test, as shown in FIG. 1, the lower housing 10 in which the sample is located, the first cover 20 which primarily isolates the sample located in the housing 10 from the outside, And a marinel beaker composed of a first cover 20 and the second cover 30 to isolate the outside secondary is widely used.
그러나, 종래에 사용되던 마리넬리 비이커는 도 2에 도시된 바와 같이 제1 덮개(20)가 하부 하우징(10)의 내부로 삽입되며, 하부 하우징(10)의 내벽이 제1 덮개(20)의 가장자리에 형성된 외벽을 압박하여 제1 덮개(20)가 하부 하우징(10)에 끼움 고정되는 구조로 이루어진다. 때문에, 제1 덮개(20)가 하부 하우징(10)의 내부로 삽입되며 하부 하우징(10)의 제1 내부공간(11)에 위치하고 있는 공기를 외부로 방출하기 위해 제1 덮개(20)에 공기 배출공(21)이 형성되어야 한다.However, in a conventionally used marinel beaker, as shown in FIG. 2, the first cover 20 is inserted into the lower housing 10, and the inner wall of the lower housing 10 is connected to the first cover 20. The first cover 20 is pressed into the lower housing 10 by pressing the outer wall formed at the edge. Therefore, the first cover 20 is inserted into the lower housing 10 and the air in the first cover 20 to discharge the air located in the first inner space 11 of the lower housing 10 to the outside. The discharge hole 21 should be formed.
따라서, 종래 마리넬리 비이커에 유체 시료가 위치 될 경우 그 시료가 배출공(21)을 통해 제1 덮개(20)와 제2 덮개(30) 사이에 형성된 제2 내부공간으로 이동하게 되어 외부로 유출되는 단점이 발생된다. 특히, 생체시료를 보관할 경우 생체시료가 부패되며 발생하는 가스를 제2 덮개(30)에서 완벽하게 차단하지 못해, 주변을 오염시키는 문제점이 발생한다. 시료가 직접적으로 외부로 유출되거나, 가스를 통해 핵종이 외부로 배출될 경우 마리넬리 비이커에 위치하는 시료의 방사능을 측정하는 방사능 측정기의 성능시험(performance test)이 명확히 수행되지 않는다. 따라서, 방사능 측정기의 성능을 검증하는 시험의 신뢰성이 하락하는 문제가 발생한다.Therefore, when the fluid sample is positioned in the conventional Marinelli beaker, the sample is moved to the second inner space formed between the first cover 20 and the second cover 30 through the discharge hole 21 and outflows to the outside. Disadvantages arise. In particular, when the biological sample is stored, the biological sample is decayed and the generated gas is not completely blocked by the second cover 30, thereby causing a problem of polluting the surroundings. The performance test of radioactivity meters that measure the radioactivity of samples placed in marineli beakers is not clearly performed if the sample is released directly to the outside or if the nuclide is released through the gas. Therefore, there arises a problem that the reliability of the test for verifying the performance of the radiometer decreases.
뿐만 아니라, 하부 하우징(10)과 제1 덮개(20)의 결합은 하부 하우징(10)이 제1 덮개(20)를 압박하는 방식이기 때문에, 방사능 측정기의 성능시험이 끝난 후 마리넬리 비이커에 보관되는 시료를 폐기시킬 시, 제1 덮개(20)와 하부 하우징(10)의 분리가 어려워 시료를 폐기 시키는 공정이 어려워지는 단점 또한 존재한다.In addition, since the combination of the lower housing 10 and the first cover 20 is a method in which the lower housing 10 presses the first cover 20, the lower housing 10 and the first cover 20 are stored in the marineli beaker after the performance test of the radiometer. When the sample is to be discarded, there is also a disadvantage that the process of discarding the sample is difficult because the separation of the first cover 20 and the lower housing 10 is difficult.
결국, 시료를 외부와 완벽하게 차단하여 시료의 운반 및 보관 과정에서 시료가 외부로 방출되는 것을 방지하고, 덮개의 개폐가 용이하게 이루어질 수 있는 감마분광분석기용 완전 밀폐형 시료 용기의 필요성이 대두 되고 있다.As a result, there is a need for a completely sealed sample container for a gamma spectrometer that can completely block a sample from the outside to prevent the sample from being released to the outside during transport and storage of the sample, and to easily open and close the cover. .

Thus, in the sample container according to the embodiment of the present invention, the first coupling part 140 of the housing 100 and the second coupling part 210 of the lid 200 are seamed.
이하에서는, 도 4 내지 도 6을 참조하여 상기 하우징(100) 및 덮개(200)의 시밍 구조 및 방법을 설명하도록 하겠다.Hereinafter, the seaming structure and method of the housing 100 and the cover 200 will be described with reference to FIGS. 4 to 6.
도 4를 참조하여 설명하면 상기 하우징(100)과 상기 덮개(200)는 서로 분리 되어 있고, 상기 하우징(100)의 상단부 가장자리에 형성된 상기 제1 결합부(140) 및 상기 덮개(200)의 상기 제2 결합부(210)가 서로 결합이 용이한 구조로 이루어진다. 하우징(100) 내부의 공간(120)에 시료를 유입시킨 후, 도 5에 도시된 바와 같이 상기 제2 결합부(210)를 상기 제1 결합부(140)와 서로 마주보게 안착시킨 후, 상기 제2 결합부(210) 및 상기 제1 결합부(140)를 함께 접거나 말아 상기 하우징(100)과 상기 덮개(200)를 서로 결합시킨다.Referring to FIG. 4, the housing 100 and the cover 200 are separated from each other, and the first coupling part 140 and the cover 200 formed on the upper edge of the housing 100 are separated from each other. The second coupling portion 210 is made of a structure that is easy to combine with each other. After the sample is introduced into the space 120 inside the housing 100, the second coupling part 210 is seated to face the first coupling part 140 as shown in FIG. 5, and then the The second coupling part 210 and the first coupling part 140 are folded or rolled together to couple the housing 100 and the cover 200 to each other.
이때, 상기 제1 결합부(140)와 상기 제2 결합부(210)를 서로 마주보게 안착시키는 과정에서, 상기 하우징(100)과 상기 덮개(200)의 상하방향 중심축이 동일선상에 위치되지 않는 것을 방지하기 위해, 도 6의 (a)에 도시된 바와 같이 상기 제2 결합부(210)는 상기 제1 결합부(140)와 마주보는 면이 내측에서 외측으로 갈수록 경사지게 기울어지도록 구성될 수 있다. 그리고, 상기 제1 결합부(140)는 상기 제2 결합부(210)의 마주보는 면의 경사에 대응하여 서로 맞닿도록 구부러지게 구성될 수 있다.At this time, in the process of seating the first coupling portion 140 and the second coupling portion 210 facing each other, the vertical axis of the housing 100 and the cover 200 is not located on the same line. As shown in FIG. 6A, the second coupling part 210 may be configured such that a surface facing the first coupling part 140 is inclined inclined from the inner side to the outer side. have. In addition, the first coupling part 140 may be bent to be in contact with each other in response to the inclination of the facing surface of the second coupling part 210.

If it is out of the problem, the coupling force is weakened. In other words, when the length of the second coupling portion 210 is insufficient or is formed too long, a problem that the sealing force is lowered may occur.
이러한 문제를 해결하기 위해서, 상기 제2 결합부(210)는 상측으로 갈수록 벌어지는 깔대기 형 구조를 가지고 상기 제1 결합부(140)는 상기 제2 결합부(210)에 끼워지도록 구성한다. 그에 따라, 상기 제1 결합부(140)와 상기 제2 결합부(210)의 서로 접히는 비율이 일정 수치 범위 내에 유지될 수 있다.In order to solve this problem, the second coupling portion 210 has a funnel-like structure that opens toward the upper side and the first coupling portion 140 is configured to be fitted to the second coupling portion 210. Accordingly, the ratio of the folding of the first coupling portion 140 and the second coupling portion 210 to each other may be maintained within a predetermined numerical range.
아울러, 도 6의 (b)에서 상기 제1 결합부(140)와 상기 제2 결합부(210)의 시밍 구조는 한번 밴딩된 형태이나, 이에 한정되지 아니하고 선택적으로 상기 공간(120)에 보관되는 시료가 외부로 방출되는 것을 방지하기 위해서 복수 번 밴딩된 형태일 수 있다.In addition, the seaming structure of the first coupling portion 140 and the second coupling portion 210 in Figure 6 (b) is a form of bending once, but is not limited to this is optionally stored in the space 120 The sample may be banded a plurality of times to prevent the sample from being released to the outside.

Thus, when the inner end of the pull tab 220 near the center point of the cover 200 is pulled upward, the outer end of the pull tab 220 presses the cutting groove 230 so that the cover 200 is It is separated into an outer cover which is located outside the shear groove 230 and an inner cover which is located inside the cutting groove 230. Thus, the sample container can be easily discharged to the outside of the sample located in the space 120 by the inner cover of the cover 200 is separated.
또한, 본 발명의 실시 예에 따른 감마분광분석기용 완전 밀폐형 시료 용기는 상기 하우징(100)의 외주면에 단수 또는 복수개의 굴곡부(150)를 구비할 수 있다.In addition, the fully sealed sample container for the gamma spectrometer according to an embodiment of the present invention may be provided with a single or a plurality of bent portion 150 on the outer peripheral surface of the housing (100).
도 7을 참조하여 설명하면, 본 발명의 실시 예에 따른 감마분광분석기용 완전 밀폐형 시료 용기는 서로 다른 시료가 섞이어 방사능 측정기의 성능 테스트의 신뢰성이 떨어지는 것을 방지하기 위하여, 일회 사용된 이후에는 대부분 폐기된다. Referring to FIG. 7, the fully sealed sample container for the gamma spectrometer according to the embodiment of the present invention is mostly used after being used once to prevent the reliability of the performance test of the radiometer by mixing different samples. Discarded.
따라서, 상기 하우징(100)은 단가가 싸며 성형이 쉬운 폴리에틸렌(PE) 재질이나 폴리프로필렌(PP)재질로 제작되나 이런 재질로 얇은 두께의 상기 하우징(100)을 구성하는 경우 내구성이 약해져, 외력에 의해 하우징(100)의 변형이 발생하는 경우가 빈번하다.Therefore, the housing 100 is made of polyethylene (PE) material or polypropylene (PP) material, which is easy to mold and low in cost, but when the housing 100 is made of such a material, the durability becomes weak, Frequently, deformation of the housing 100 occurs.
상기와 같은 단점을 해소하기 위해, 본 발명의 실시 에에 따르면 도 7에 도시된 바와 같이 상기 하우징(100)의 외주면에 다각형의 단면을 가지는 굴곡부(150)를 구비하여, 외부 압력에 대해서 상기 하우징(100)의 내구성이 향상되게 구성할 수 있다.In order to solve the above disadvantages, according to the embodiment of the present invention, as shown in FIG. 7, the outer peripheral surface of the housing 100 is provided with a bent portion 150 having a polygonal cross section, the housing ( 100) can be configured to improve the durability.
이때, 상기 굴곡부(150)는 외력에 효과적으로 대응 가능하다면 그 굴곡의 단면 형상이 다양한 형태를 가지도록 구성될 수 있다. At this time, the bend 150 may be configured to have a variety of forms of cross-sectional shape of the bend if it can effectively respond to the external force.
또한, 본 발명의 실시 예에 따른 감마분광분석기용 완전 밀폐형 시료 용기에서 고정부(130)는 상기 하우징(100)의 상하 길이방향 중심축을 기준으로 일정한 반경(r)을 가지는 원통 형상으로 이루어지는 것이 바람직하다.In addition, in the fully sealed sample container for the gamma spectrometer according to an embodiment of the present invention, the fixing part 130 is preferably made of a cylindrical shape having a constant radius (r) with respect to the vertical longitudinal axis of the housing (100). Do.
도 8을 참조하여 상세히 설명하면, 상기 시료 용기의 상기 고정부(130)에는 방사능 측정기가 삽입되고, 상기 삽입된 방사능 측정기는 상기 하우징(100) 내에 존재하는 시료의 방사능을 측정한다. Referring to FIG. 8, a radiometer is inserted into the fixing part 130 of the sample container, and the inserted radiometer measures radioactivity of a sample present in the housing 100.
여기서, 상기 고정부(130)를 중심으로 그 주변에 시료가 채워지고 상기 시료가 채워지는 공간의 a, b, c 값이 서로 동일하지 않은 경우에는, 시료를 구성하는 방사성 핵종에서 방출된 방사선의 자기흡수(self absorption) 양이 변형되어 상기 삽입된 방사능 측정기에서 측정되는 방사능 수치에 오차가 발생하게 된다.Here, when the sample is filled around the fixing part 130 and the a, b, and c values of the space where the sample is filled are not equal to each other, the radiation emitted from the radionuclides constituting the sample is measured. The amount of self absorption is modified so that an error occurs in the radiation level measured by the inserted radiometer.
그러므로, 이러한 오차를 방지하기 위해서 상기 고정부(130)는 상기 하우징(100)의 상하 길이방향 중심축을 기준으로 일정한 반경(r)을 가지는 원통 형상을 가지도록 구성하는 것이 바람직하다. 상기 고정부(130)가 상기 원통 형상을 가지는 경우, 상기 하우징(100) 내 시료가 채워지는 공간(120)의 b,c 값이 서로 동일해 지도록 상기 하우징 내 공간(120)을 구성할 수 있다. 그리고, 상기 고정부(130)의 상측에 시료가 채워지는 높이인 a 값 역시 상기 b, c 값과 동일하게 조절될 수 있도록 상기 하우징(100)에는 a값을 육안으로 확인할 수 있는 눈금을 구비하는 것이 바람직하다.Therefore, in order to prevent such an error, the fixing part 130 is preferably configured to have a cylindrical shape having a constant radius (r) based on the vertical longitudinal axis of the housing (100). When the fixing part 130 has the cylindrical shape, the space in the housing 120 may be configured such that the b and c values of the space 120 in which the sample in the housing 100 is filled are equal to each other. . In addition, the a value, which is a height at which the sample is filled on the upper side of the fixing part 130, is also provided with a scale for visually checking the a value in the housing 100 so that the b value and the same value as the c value can be adjusted. It is preferable.
이와 같이, 상기 하우징(100) 내에 시료가 채워지는 공간의 a, b, c 값이 서로 일치되도록 해 줌으로써, 상기 고정부(130)에 삽입된 방사능 측정기를 통해 시료의 방사능을 보다 정확하게 측정할 수 있다. As such, by allowing a, b, and c values of the space in which the sample is filled in the housing 100 to coincide with each other, the radioactivity of the sample can be more accurately measured through the radiometer inserted into the fixing part 130. have.

Therefore, when the sample from which a large amount of gas is discharged is located in the space 120, it is preferable that the cover 200 is made of a gas permeable material.
그리고, 핵종이 가스에 함유되어 외부로 방출될 가능성이 있는 시료가 상기 하우징(100)의 공간(120)에 위치될 경우에는, 덮개(200)를 가스 비투과성 재질로 구성하는 것이 바람직하다. 이 경우, 덮개(200)를 가스 비투과성 재질로 구성하여 핵종이 외부로 방출되지 않도록 해 줌으로써, 방사능 측정 시험에서 발생할 수 있는 사고를 미연에 방지할 수 있다.In addition, when the sample containing the nuclide contained in the gas and is likely to be released to the outside is located in the space 120 of the housing 100, the lid 200 may be made of a gas impermeable material. In this case, the cover 200 is made of a gas-permeable material to prevent the nuclide from being released to the outside, thereby preventing accidents that may occur in the radioactivity test.
