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 specifically, a gamma-ray spectrometer that blocks an external outflow of a radioactive gas generated from a measurement sample or measurement sample through screw coupling and fitting. It relates to a sealed container for measuring radon radioactivity using a.

In general, referring to the Republic of Korea Patent No. 10-1738888 in the measurement of radioactivity using a gamma-ray spectroscopy apparatus, the lower housing 10 and the housing 10, the sample is located as shown in Figure 1 A sealed container composed of a first cover (20) that primarily isolates the sample from the outside and maintains a constant volume, and a second cover (30) that isolates the outside of the first cover (20) and the outside. It is widely used.

However, the conventionally used sealed container is the first cover 20 is inserted into the interior of the lower housing 10, as shown in Figure 1, the inner wall of the lower housing 10, the edge of the first cover 20 It is made of a structure in which the first cover 20 is fitted to the lower housing 10 by pressing the outer wall formed on it. Therefore, the first cover 20 is inserted into the interior of 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.

Therefore, when a fluid sample is placed in a conventional sealed 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 then leaks to the outside. The disadvantage is that. 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 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 the sample located in the sealed container is not clearly performed. Therefore, a problem occurs in that the reliability of the test for verifying the performance of the radiometer is deteriorated.

In addition, in the case of a conventional sealed container, there are three basic components for sealing: a lower housing 10, a first cover 20, and a second cover 30, and are simple in combining or separating three components. There was a problem in that the coupling or separation was inconvenient because it uses a seaming operation, which is a joining operation that is crimped or folded or bent or rolled together.

After all, the sample is completely blocked from the outside to prevent the sample from being released to the outside during the transport and storage of the sample, and the cover can be easily opened and closed, and additional configuration is minimized to be applicable to a special experimental environment. The need for a sealed container designed for gamma spectroscopy has emerged.
