Embodiment Construction

[0047] The radioactive decontamination efficiency test method of the present invention is described in detail below in conjunction with accompanying drawing of specification sheet and embodiment:

[0048] A method for testing radioactivity decontamination efficiency, comprising the following steps:

[0049] (I) Test the decontamination efficiency of the decontamination agent on radioactive dust in the air

[0050] (i) Clean up the spray box 1 and connect it to the bottom support 18 with the compression bolt 17, close the front operation door 13, the rear operation door 14 and the air sampling port 15, and open the damper 9;

[0051] (ii) Add a certain amount of radioactive dust to the radioactive dust addition port 6, and close the radioactive dust addition port 6;

[0052] (Ⅲ) Turn on the blower fan 5 to blow the radioactive dust into the spray box 1, and keep blowing air for a period of time;

[0053] (iv) Turn off the fan 5 and open the air sampling port 15 to sample and ...

Abstract

The invention discloses a radioactive decontamination efficiency test method. The test method comprises the following steps: (I) testing the decontamination efficiency of detergent on radioactive dustin the air; and (II) testing the decontamination efficiency of the detergent on the surface contaminated by the radioactive dust. The invention provides a radioactive decontamination efficiency testmethod, which comprises a test method for the decontamination efficiency of the detergent on the radioactive dust in the air and a test method for the decontamination efficiency of the detergent on the surface contaminated by the radioactive dust; quantitative analysis is carried out on the spraying amount of the detergent, the atomizing effects of different atomizing nozzles are compared and analyzed so as to judge whether radioactive nuclides can be effectively captured by the detergent. According to the test method disclosed by the invention, measurement is mainly carried out in a closed box body, and diffusion of the radioactive dust in a large amount is not caused.

Description

technical field [0001] The invention belongs to the field of radioactive waste treatment in the nuclear industry, and in particular relates to a radioactive decontamination efficiency test method. Background technique [0002] The emergency disposal method of radioactive contamination film method is an advanced technology for dealing with the radioactive consequences of nuclear accidents and radiation terrorism. In the national nuclear emergency decontamination and decontamination force, the equipment decontamination and decontamination, the sealing and control of the source of the accident, and the pollution suppression operation capabilities of high-altitude and large-area radioactively contaminated areas on the ground are all based on the demonstration and construction of membrane diffusion control and membrane decontamination agents. [0003] Radioactive pollution decontamination agent is the material basis of membrane technology application system. Its main function is...
