Abstract

The invention discloses a device for adsorbing radon gas by ZIF-8. The device comprises a standard gas chamber (2) including the radon gas, wherein gas inlets and gas outlets are arranged in the standard gas chamber (2) and interconnected through a gas pipe; an adsorbing device (14), an air pump (8), a flow meter (10) and a gas detector are arranged on the gas pipe (4). The ZIF-8 is used as the adsorbing device, and the porous structure of the device has the good adsorption effect; besides the device adopts a cyclic adsorption form for thorough adsorption, and the radon gas in the radon gas chamber is in the relative steady concentration range.

Description

technical field [0001] The invention relates to a device for absorbing radon gas through ZIF-8. Background technique [0002] The radiation hazard of radon and its progeny has been confirmed by the International Agency for Research on Cancer (IARC) as one of the important causes of lung cancer. The U.S. Environmental Protection Agency has listed radon as the most dangerous carcinogen. Radon radioactive pollution is also the main cause of leukemia and so on. Building materials (especially fly ash bricks, slag bricks, stone coal bricks, slag and slag cement) are the main sources of radon and radioactive pollution in residential buildings, and uranium (thorium) mines are also the main source of radon and its daughters. [0003] The pathogenic mechanism of radon and its progeny is such that radon and its progeny can be attached to aerosol particles in the air and suspended in the air. When inhaled into the body, some short-lived solid daughters of radon can be deposited on the...
