Abstract

The invention relates to a peelable radionuclide decontamination agent and a preparation and utilization method thereof. The peelable radionuclide decontamination agent is prepared from, by weight, 5-8 parts of an organic functional component, 25-30 parts of a foam stabilizer and 18-22 parts of a coalescing agent. The utilization method includes steps: S1, wet decontamination agent preparation; S2, film formation and decontamination; S3, drying and film peeling. The peelable radionuclide decontamination agent has advantages of low pollution, high universality, easiness in waste treatment and low cost.

Description

technical field [0001] The invention relates to the technical field of nuclide decontamination, in particular to a detachable radionuclide decontamination agent and a preparation and use method thereof. Background technique [0002] A number of nuclear facilities have expired one after another, and their decommissioning has become an important part of nuclear waste management. After decontamination, they can be used in general occasions. There are many methods for decontaminating nuclear facilities. Such as sandblasting cleaning, ultrasonic cleaning, dry ice cleaning, chemical cleaning, etc. However, these methods have various disadvantages: for example, the treatment will be accompanied by the formation of a large amount of radioactive dust and the generation of secondary pollutants, which will seriously pollute the working environment, which will bring serious harm to the health of operators and the environment. , In some cases, even explosive mixtures will be formed; ul...
