Description
(1) technical field
The present invention relates to a kind of dusty gas treatment technology, specifically a kind of apparatus for purifying radioactive gas.
(2) background technology
Radioactive pollutant is meant various radioactive nuclides, and it and general chemical pollutant have remarkable difference, and promptly the radioactivity of radioactive pollutant and its chemical state are irrelevant.Each radioactive nuclide all has certain half life period, can radiate the ray with certain energy.Except under the nuclear reaction condition, any chemistry, physics or biochemical processing all can not change this characteristic of radioactive nuclide.
After radioactive nuclide enters in the environment, can cause pollution to atmosphere, water body and soil, because atmospheric diffusion and current conveying can obtain dilution and move radioactive nuclide at nature can be by biological concentration, make some animal, plant, particularly increase manyfold in the concentration ratio environment of radioactive nuclide in some aquatic organisms.For example (concentration of Zn can reach 100,000 times of concentration in the seawater on every side to the isotope of the zinc in the oyster meat.Radioactive nuclide in the environment can enter human body by number of ways, makes the people be subjected to the radioactivity injury.
After radgas was released into environment, the course of conveying in atmosphere was subjected to multiple factor affecting such as meteorological condition, landform and character own.Radgas enters behind the atmosphere in the diffusion of flat country, generally adopts the Pasquill formula to come the mean concentration of quantitative description leeward radiotropism smoke, mists and clouds to distribute.
Radgas produces irradiation injury to the people three kinds of modes usually: 1. submergence irradiation: human body is immersed in the alpha-contamination air, and whole body and skin can be subjected to external exposure.2. suck irradiation: suck radgas, make whole body or organs such as thyroid gland, lung be subjected to internal radiation.3. sedimentation irradiation: be deposited on the irradiation of the radioactive material confrontation people generation on ground, as producing the γ external exposure or producing internal radiation in the human body by transferring to.The dosage of the sedimentation irradiation generally dosage than submergence irradiation and suction irradiation is little, but the illeffects longer duration.
At present, the processing mode of radgas is generally had two kinds: a kind of is direct emission type, be exactly with radgas directly by discharge of pipes in atmosphere.But there is regulation in country, and discharge tube should be higher than Nuclear Medical Laboratory more than 10 meters, and the surrounding buildings thing should encircle outside the scope of 50 meters of discharge tubes, but is difficult to reach national regulation in the reality; Another kind is the sewer emission type, and the discharge tube that is about to discharge radgas is incorporated among the sewer, and this discharging modes still can not fundamentally solve the harm of radgas.
