Embodiment 1

[0015] Such as figure 1 As shown, the temperature and humidity controllable tritium content automatic measurement system includes a first temperature and humidity control room 3, and the first temperature and humidity control room 3 is provided with a room 2 for storing samples containing tritium to be tested, and also includes a room surrounded by the first temperature and humidity control room 3 A second temperature and humidity control room 4 outside the temperature and humidity control room 3; the inner and outer walls of the first temperature and humidity control room 3, and the inner wall of the second temperature and humidity control room 4 are all provided with a temperature test unit 5, as shown in the figure Arranged on the inner wall of the first temperature and humidity control room 3 is a first temperature test unit 51, and arranged on the outer wall of the first temperature and humidity control room 3 is a second temperature test unit 52, which is arranged at the s...

Embodiment 2

[0018] The first temperature and humidity control room 3 and the second temperature and humidity control room 4 both include a thermal inert body, a constant temperature control structure surrounding the outer surface of the thermal inert body, and a heat insulation structure surrounding the outer surface of the constant temperature control structure. The heat insulation structure includes a shell and an insulation body, and the insulation body is filled between the shell and the thermostatic control structure. Preferably, the thermal inert body is a shell-like structure made of pure aluminum with uniform wall thickness everywhere. Preferably, the heat insulation structure is a cotton stone board.

Embodiment 3

[0020] There are multiple temperature test units 5, which are evenly distributed on the inner wall and outer wall of the first temperature and humidity control room 3 and the inner wall of the second temperature and humidity control room 4. Multiple temperature test units 5 are beneficial to test the accuracy of the ambient temperature. Exhaust test accuracy problems caused by local temperature differences.

Abstract

The invention discloses an automatic measuring system of the content of tritium capable of controlling the humiture. The automatic measuring system comprises a first humiture control chamber, the first humiture control chamber is internally provided with a sample chamber for storing a to-be-detected tritium sample, the automatic measuring system further comprises a second humiture control chamberwhich surrounds the outer part of first humiture control chamber; and temperature testing units are arranged on the inner wall and the outer wall of the first humiture control chamber and the inner wall of the second humiture control chamber.

Description

Technical field: [0001] The invention relates to the detection of tritium, in particular to a temperature and humidity controllable tritium content automatic measurement system. Background technique: [0002] Tritium (also called superheavy hydrogen) is a radioactive isotope of hydrogen. Tritium beta particles are a kind of low-energy rays that will not cause harm to the human body and do not require external radiation shielding protection. The International Commission for Reflection Protection (ICRP) only classifies tritium as a low-toxic radionuclide. However, entering the human body through inhalation, skin penetration or ingestion will cause internal radiation damage, and even death in severe cases. Naturally occurring tritium generally exists as HTO or HT molecules. Tritium detection is mainly used for production and radiation protection purposes. At the tritium production site, the toxicity of tritated water is 104 times that of gaseous tritium, so liquid or gaseous HTO ...
