Description

Technical Field

[0001] This utility model relates to the field of tritium sampler technology, and more particularly to an air tritium sampler. Background Technology

[0002] Tritium, also known as superheavy hydrogen, is an isotope of hydrogen, with the element symbol T or 3H. Its atomic nucleus consists of one proton and two neutrons, and it is radioactive, undergoing beta decay with a half-life of 12.43 years. Because the beta decay of tritium only releases high-speed electrons that cannot penetrate the human body, only inhaling large amounts of tritium is harmful. In nature, tritium is a byproduct of the interaction between cosmic rays and nitrogen-14 nuclei in the atmosphere. It is also one of the radioactive substances released in the "secondary radiation" of nuclear explosions.

[0003] A search revealed that patent document CN104932003A discloses a mobile, high-flow-rate, rapid tritium sampling device. This device includes an air sampler on the upper left side of the housing, an integrated film control panel for the air sampler, and pagoda nozzles II and IV. On the lower left side of the housing are a heating chamber, a catalytic heater, a control switch, pipes I and II, pagoda nozzles I and III, and a low-temperature chamber, a condenser, a compressor, and an integrated film control panel for the low-temperature chamber. It also includes hoses I and II. The connection is as follows: the air sampler contains the integrated film control panel, and the left and right sides of the air sampler are connected to pagoda nozzles IV and II respectively via pipes.

[0004] While the aforementioned comparative document combines catalytic oxidation and efficient cooling methods to achieve rapid sampling of total tritium in the environment, its small size and portability make it effective for collecting total tritium samples in any environment, including nuclear emergency environments and workplaces. However, the pipes and hoses of this device are located outside the enclosure, making them susceptible to damage from impacts when not in use, requiring replacement. Frequent replacements increase unnecessary costs. Therefore, an air tritium sampler is proposed. Utility Model Content
