Description

Airtight Container for Radioactivity Measurement Such as Radon Using Gamma-ray Spectrometer}

The present invention relates to a sealed container for measuring radioactivity such as radon using a gamma ray spectroscopy analyzer, and more particularly, a gamma ray spectroscopy analyzer that blocks external leakage of a measurement sample or radioactive gas generated from a measurement sample through screwing and fitting. It relates to a sealed container for measuring radon radioactivity using.

In general, referring to Korean Patent Registration No. 10-1738888 for radioactivity measurement using a gamma ray spectroscopy device, as shown in FIG. 1, the lower housing 10 in which the sample is located, and the housing 10 An airtight container composed of a first cover 20 that primarily isolates the sample from the outside and maintains a fixed volume, and a first cover 20 and a second cover 30 that secondaryly isolates the outside. It is widely used.

However, in the conventional sealed container, as shown in FIG. 1, the first cover 20 is inserted into the lower housing 10, and the inner wall of the lower housing 10 is the edge of the first cover 20. The first cover 20 is fitted to the lower housing 10 by pressing the outer wall formed in the structure. Therefore, the first cover 20 is inserted into the interior of the lower housing 10, and air is placed in the first cover 20 to discharge air located in the first interior space 11 of the lower housing 10 to the outside. The discharge hole 21 must be formed.

Therefore, when a fluid sample is placed in a conventional airtight container, 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 is discharged to the outside. There is a disadvantage to be caused. In particular, when the biological sample is stored, the biological sample is decayed and the gas generated cannot be completely blocked by the second cover 30, resulting in a problem of contaminating the surroundings. When a sample is directly discharged to the outside or a nuclide is discharged to the outside through a gas, a test for measuring the radioactivity of a sample placed in an airtight container is not clearly performed. Therefore, there arises a problem that the reliability of a test for verifying the performance of the radioactivity meter decreases.

In addition, in the case of a conventional airtight container, three basic components for sealing are the lower housing 10, the first cover 20, and the second cover 30, and it is simple to combine or separate the three components. There is a problem that it is inconvenient to combine or separate because it uses a seaming joint, which is a joint operation that is crimped or folded and bent or rolled together.

In the end, the sample is completely blocked from the outside to prevent the sample from being released to the outside during the transportation and storage of the sample, the cover can be easily opened and closed, and the additional configuration is minimized so that it can be applied to a special experiment environment. Thus, the necessity of a sealed container for a designed gamma spectroscopy analyzer is emerging.
