Embodiment

[0029] When using radon exposure and poisoning experimental equipment, first put the experimental animals or measuring instruments into the exposure chamber 1, close the exposure chamber 1 and the exposure air flow controller 10, open the compressed air source 5, the exposure circulation pump 8 and the charging source circulation pump7. Adjust the filling source flow controller 12 to transport the radon gas produced by the radon source 3 to the accumulation chamber 4 through the filling source loop 14, adjust the accumulation air flow controller 9 and monitor the radon measuring instrument 6 on the radon measuring loop 15 to make the accumulation chamber 4 The contents of radon gas and its daughters meet the requirements. Adjust the exposure radon flow controller 11, drive the predetermined content of radon and its progeny to the exposure chamber 1, and start the animal radon exposure experiment; in the experiment, adjust the exposure radon flow controller 11 to further adjust...

Abstract

The invention provides radon exposure poisoning experimental equipment. In the equipment, a radon source capable of generating radon is connected with a source charge loop to an accumulation chamber; a source charge circulating pump and a source charge flow controller regulate the accumulation amount of radon in the accumulation chamber; an air compressed air source supplies air to the accumulation chamber through an accumulated air flow controller, and the content of radon in the accumulation chamber is monitored by an emanometer through a radon measurement loop; radon with a preset content and a corresponding daughter are delivered to an exposure bin which is provided with an experimented animal or the corresponding measurement instruments through an exposure loop, an exposure circulating pump and an exposure radon flow controller; waste gas is safely exhausted through an exhaust pipeline with an exhaust flow controller and a waste gas treatment device; and the whole equipment is completely closed and has no leakage. The invention has the beneficial effects that: animal exposure poisoning equipment which is completely closed and safe, has no leakage, and can freely adjust the content of radon is provided, can be widely applied in the studying fields of environmental science, radiological medicine, human health and the like, develops a novel method, and provides a novel experimental means.

Description

[0001] technical field [0002] The invention relates to an experimental equipment for radon gas exposure and poisoning. Background technique [0003] Radon gas is ubiquitous in nature. The pollution of radon gas and its progeny is an important cause of human lung cancer and other diseases. At present, what is most lacking is precise quantitative control, convenient operation, safety and no leakage, intuitive and reliable simulation and special equipment for manufacturing radon environmental exposure exposure, which seriously restricts the development of scientific research in this area. Contents of the invention [0004] The purpose of the present invention is to provide a kind of radon gas exposure and poisoning experimental equipment, which provides a kind of accurate quantitative control, convenient operation, safety and no leakage, and intuitive Reliable experimental equipment for radon exposure and poisoning provides new methods and equipment for scientific research...
