Description
Technical Field
The invention belongs to the field of decontamination solutions, and particularly discloses a radioactive contamination decontamination solution and preparation and application thereof.
Background
The radioactive contamination is that radioactive substances generated in nuclear radiation and nuclear explosion accidents are contaminated to surrounding personnel, equipment, animals, plants and environments, wherein the radioactive substances mainly comprise nuclear fission products, induced radioactive substances and non-fission nuclear charges; the main ways of causing staining are:
(1) The radioactive falling ash is settled in the air in a settling mode, is deposited on the ground, is adhered to the surfaces of human bodies and objects, and is suspended in the air and water, so that the environment is polluted and the like;
(2) Some elements in the environment are made radioactive in such a way that induced radioactivity is generated, causing internal contamination.
The radioactive contamination elimination is a washing and eliminating action for eliminating radioactive contamination of an infected object or reducing the contamination degree of the infected object, and comprises washing, wiping, flapping, sweeping, masking, filtering, curing and transferring and the like, and no matter chemical elimination or physical elimination, the structure, the composition and the property of atomic nuclei cannot be changed, namely the inherent attenuation law cannot be changed, the radioactivity of the atomic nuclei cannot be eliminated, in order to reduce the radioactive hazard of radioactive substances and reduce the contact danger, the only method is to remove the radioactive substances from the polluted surface, and the elimination degree mainly depends on the contamination characteristics of the radioactive substances, the used eliminating agent, the eliminating method and the like.
At present, the common radioactive contamination eliminators on the market mainly comprise a surface active eliminator, a chelating eliminator, a redox eliminator, an acid-base eliminator, a strippable film eliminator and a self-brittle eliminator; each has advantages and disadvantages, and the targeted radionuclides are different, and the application scenes are also different;
chinese patent CN111870595A nuclide decontamination solution, and preparation method and application thereof, wherein the nuclide decontamination solution comprises, by weight, 0.3-6% of pentasodium diethylenetriamine pentaacetate, 0.1-5% of an auxiliary chelating agent, and 0.1-up to c2 percent of adsorbent, 0.1 to 2 percent of surfactant, 1 to 10 percent of preservative, 0.1 to 1 percent of defoaming agent, 0.1 to 1 percent of acid-base regulator, 0.1 to 2 percent of stabilizer and the balance of water. The invention belongs to a combination product of a chelate type eliminator and a surface active type eliminator, and has the advantages of high decontamination efficiency, wide application range, strong environmental adaptability and long storage time. But it has problems that the contaminants are only 32 P, the infected object is only pig skin, the experimental process is carried out by a decontamination instrument, the infection time is only 1 minute, the decontamination time is also only 1 minute, the analysis is carried out on the patent right requirements and the experimental reports, 32 the P nuclide is completely different from the actinide or transition metal nuclide in performance, and 32 the P nuclide is particularly small in application, is only used in nuclear medicine, does not have wide application, and is not a representative radionuclide, so that the P nuclide cannot be explained to have a good decontamination effect on actinide nuclides or transition metal nuclides. Is the subject of the infection only pigskin, then in addition to pigskin, does it have an effect on the surrounding environment such as stainless steel, ceramic tiles, plastics, etc.? In the experimental process, the decontamination instrument is used, and then the decontamination instrument is not used in the actual use process, and whether the decontamination effect is the same or not? The reproducibility of the experimental process cannot be completed; the contamination time is only 1 minute, the decontamination time is also only 1 minute, and the contamination is equivalent to the washing with dripping, but in the actual process, the situation can be processed by using a rag, a series of problems such as the situation that the contamination time is very long and the radionuclide permeates below the surface are not solved, the environmental adaptability is strong and the storage time is long are declared, and the data which does not support the decontamination data in the environments such as plateau, rainforest and the like and the stability experiment data under high temperature and low temperature are not provided, so the method is contradictory to the patent authority requirements;
chinese patent CN111269761A decontamination liquid and application thereof in decontamination of actinide nuclide and transition metal nuclide pollution, wherein each 100 weight parts of the decontamination liquid contains 0.8-1.2 parts of 2-hydroxyphosphonoacetic acid, 6-8 parts of nitrilotrimethylene phosphate, 6-8 parts of 2-phosphonic acid butane-1,2,4-tricarboxylic acid, 0.8-1.2 parts of ethylene diamine tetramethylene phosphate and 3-5 parts of hydroxy ethylidene diphosphonic acid. The method is used for decontamination of the pollution of the steel nuclide and the transition metal nuclide, and can be better used for decontamination of the pollution of the steel nuclide and the transition metal nuclide on the skin. However, the method has the problems that the high-concentration phosphorus-containing organic acid has high acidity and can soften the cutin of the skin, and the phosphorus-containing organic acid can be adsorbed on the cutin and the surface of a cell membrane to irreversibly damage the skin; the phosphorus-containing organic acid causes secondary pollution to the environment in the use process, for example, after the stainless steel surface is washed and disinfected, the residual phosphorus-containing organic acid continues to react with the stainless steel surface to cause corrosion, further affecting the overall structure, and causing more serious corrosion to instruments and equipment.
