Description

{Marinelli Beaker for Gamm Spectroscopy with a Screw type Hermetic Cap} for gamma-ray spectroscopy using a screw-

The present invention relates to a Marinelli beaker for gamma-ray spectrometry using a threaded closed lid. In detail, the present invention includes a beaker for holding a sample to be measured for radioactivity, a cover for blocking a sample introduced into the beaker from the outside, and a screw type closed lid having a lid integrated with the lid, To a marinelli beaker for a gamma ray spectrometer employing a screw-type hermetic lid for blocking external leakage of the sample.

Generally, referring to Korean Patent No. 10-1738888 in a radiation measurement using a gamma ray spectrometer, a lower housing 10 in which a sample is placed as shown in FIG. 1, A marinelli beaker composed of a first lid 20 for primarily isolating the sample from the outside and a second lid 30 for secondarily isolating the first lid 20 from the outside is widely used.

2, the first lid 20 is inserted into the lower housing 10, and the inner wall of the lower housing 10 is inserted into the first lid 20 And the first lid 20 is fitted and fixed to the lower housing 10 by pressing the outer wall formed at the edge. The first lid 20 is inserted into the lower housing 10 and air is supplied to the first lid 20 to discharge the air located in the first inner space 11 of the lower housing 10 to the outside An exhaust hole 21 should be formed.

Therefore, when the fluid sample is placed in the marinelli beaker, the sample moves to the second inner space formed between the first cover 20 and the second cover 30 through the discharge hole 21, . In particular, when the biological sample is stored, the biological sample is corroded and the generated gas can not be completely blocked by the second lid 30, thus causing a problem of contamination of the surroundings. A test to measure the radioactivity of a sample placed in a marinelli beaker is not clearly performed when the sample is directly discharged to the outside or the nuclear paper is discharged through the gas. Therefore, there is a problem that the reliability of the test for verifying the performance of the radiation measuring apparatus falls.

In addition, since the lower housing 10 and the first lid 20 are pressed together by the lower housing 10, the performance of the radioactivity measuring device is tested and stored in a marinelli beaker. It is difficult to separate the first lid 20 and the lower housing 10, which makes it difficult to dispose of the sample.

As a result, there is a need for a sealed container for a gamma spectrometer, which can prevent the sample from being discharged to the outside during the transportation and storage of the sample, and can easily open and close the cover.
