Problems solved by technology

Although this method has high sensitivity and accurate results, it is complicated to operate, inconvenient to measure on-site, easy to pollute or leak air in the scintillation vial, and obtains little water radon observation data every day.
[0008] In the existing water radon measurement technology, there are mainly the following problems in the field of earthquake precursor water radon observation: one, it is a continuous automatic measurement problem
The current water radon measurement method in the earthquake department is the scintillation chamber method of manually collecting water samples and bubbling. The daily measurement data is small and cannot meet the analysis requirements of observation data.
Second, it is the problem of measurement accuracy
The current scintillation chamber method of manually collecting water samples and bubbling in the seismic department cannot c...

Embodiment Construction

[0044] The specific embodiments of a continuous water radon automatic measurement method and device provided by the present invention will be further described in detail below.

[0045] A continuous water radon automatic measuring device comprises a water quality filter unit 1 , an air-water exchanger unit 2 , a water vapor condenser unit 3 and a radon measuring instrument unit 4 .

[0046] Such as figure 2 As shown, the water quality filter unit 1 is made up of three-way switch valve 11, iron hoop 12, screen filter 13, fixing screw 14 and PVC hose 15. The PVC hose 15 is enclosed within between the three-way switch valve 11 and the strainer filter 13, and the iron hoop 12 is screwed on its connection position to ensure that the water quality filter unit 1 does not leak when it is connected to the high-pressure faucet. The filter screen filter 13 is made up of upper top cover 131, shell 132, filter screen 133 and liquid outlet 134, and water flows into filter screen 133 throu...

Abstract

The invention discloses continuous type automatic measurement method and apparatus for radon in water. In the invention, it is proved that radon gas exchanges between gas phase and liquid phase and satisfies Henry's Law, namely, dissolution equilibrium state; and the concentration of radon in water can be calculated by an equation of Cw = F*Cg; meanwhile, the invention provides experiment measurement steps of water temperature T relative to the equilibrium factor F. The measurement apparatus includes: a water filter unit, a gas-water exchanger unit, a water vapor condenser unit, and a radon detector unit. The measurement apparatus has simple operation, is high in intelligent degree, has digital measurement function, saves manpower and drying agent, can continuously measure the concentration of radon in water for a long period, is more complete, stable and accurate in measurement data of the radon in water, and can supply a more reliable digital measurement result for the radon in waterto observation of geologic structure and earthquake precursor.

Description

technical field [0001] The invention relates to a water radon measuring method, in particular to a continuous water radon automatic measuring method and device. Background technique [0002] Radon gas is the decay product of radium in the three natural radioactive systems, and is a colorless, odorless, radioactive, inert gas. Radon gas is soluble in water and widely distributed in groundwater. Because radon gas has unique physical and chemical properties and strong earthquake reflection, it occupies an important position in the observation of underground fluids in the seismic industry. Water radon observation can most intuitively capture the change of water radon concentration in groundwater, and then provide a theoretical basis for the study of earthquake precursors. [0003] Water radon measurement methods include liquid scintillation counting method, scintillation chamber method, gamma energy spectroscopy, alpha energy spectroscopy, etc. [0004] Gamma energy spectrosc...
