Abstract

The invention belongs to the technical field of a test for diffusion-seepage of radon gas in the internal of radon gas medium, and particularly relates to a multifunctional test device for diffusion and seepage of radon in broken emanation medium. The device comprises a top cover, a multi-layer sample loading barrel body, a porous bottom plate, and a bottom cover of the device. The top cover comprises a stainless steel body, a top cover self-locking quick-connection interface, and a top cover lifting handle. The multi-layer sample loading barrel body comprises a stainless steel barrel body, abarrel body self-locking quick-connection interface, a gas collector, and a barrel body lifting handle. A gas collector is installed in each layer of the stainless steel barrel body. The whole deviceis simple in structure, flexible in installation, convenient to assemble and disassemble, long in service life, and reusable. The sample loading barrel body is composed of six sections of different heights, and can be installed and fed layer by layer in a sample loading process, so that the device is convenient to use. Meanwhile, the height of the barrel body of the test device can be flexibly adjusted, thereby meeting test conditions of the sample under different loading heights and reflecting the flexibility and versatility of the device.

Description

technical field [0001] The invention belongs to the technical field of radon diffusion-seepage test inside a broken emanation medium, and in particular relates to a multifunctional radon diffusion and seepage test device for a broken emanation medium. Background technique [0002] Radon is the decay daughter of natural radioactive radium, which is also radioactive. After people inhale air containing radon, radioactive radon and its decayed substances will be deposited in the respiratory tract, which will cause radiation damage to the human body and may cause lung cancer. The United Nations Scientific Committee on the Effects of Atomic Radiation once pointed out in a report that the radiation dose produced by inhalation of radon and radon daughters worldwide accounts for about 50% of the annual effective dose equivalent of natural radiation for all human beings. [0003] As an inert gas, radon migrates more easily than any other gas. It is soluble in water and organic matter...
