Background

Tritium is a low-energy beta emitter widely existing in the environment, and natural tritium existing in nature is extremely micro and mainly formed by bombardment of 16O and 16N in the atmosphere by neutrons and protons in cosmic rays. After human beings have developed tritium production activities, various tritium species that are emitted to the surface or to the atmosphere in gaseous, liquid or solid form constitute a significant portion of the environmental tritium source. Tritium is used as an important radioactive gas nuclide discharged by a fission power operation reactor, and tritium leaked into the surrounding environment by various nuclear facilities can cause the increase of the activity of tritium in the atmosphere of the surrounding environment. Workers working in the reactor plant of the nuclear power plant and related auxiliary plants inevitably take tritium in various ways, so that internal irradiation damage is caused to a certain extent. Therefore, how to measure tritium activity in air with high precision is a key issue for gaseous tritium measurement.

At present, the tritium is not wide in application range, and the measuring method is few, and mainly comprises the following two steps, namely firstly, tritium is catalyzed and oxidized into tritiated water and then is measured by a scintillator detector; the second is to measure the gas by using a gas detector such as an ionization chamber and a proportional counter. The two are oriented to different measuring objects, and then different signal processing systems are adopted to integrate signals output by the detector and transmit the signals to the measuring software through the communication module.

Often tritium is when detecting in the pipeline, can lead to the damage at the pipeline because other reasons, and tritium detects and mends the ware and can't report to the police according to the reduction of tritium content, consequently needs a device that can monitor tritium and detect the heterochange of pipeline, and when detecting that the pipeline removed or change, the user can cross and obtain the notice.
