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...
