Embodiment 2
[0040] Example 2 The decontamination efficiency measurement of the decontamination wet tissue to the radionuclide-contaminated skin
[0041] 1. Establishment of skin model
[0042] Small fragrant pigs were intraperitoneally injected with 40mg / kg sodium pentobarbital, and the skin was prepared. 60 co 2+ 、Sr 2+ 、Cs +solution, diluted to 10 4 Bq / mL, take 300 μL of the poisoned solution and apply it evenly in a 5cm×5cm area, and let it dry naturally for 5 minutes.
[0043] 2. Preparation of decontamination wipes
[0044] Prepare decontamination wipes with different components, and divide them into groups A, B, C, D, and E according to different decontamination solutions. Group A: distilled water; B: 6% disodium edetate; C: 0.7 % tetradecyl dimethyl amine oxide; D: 0.5% sodium laureth sulfate; E: 2% sodium bicarbonate; F: mixed solution formula group. Each group soaked the non-woven fabric separately.

Embodiment 3
[0052] Example 3 Decontamination method optimization of decontamination wet wipes to radionuclide-contaminated skin
[0053] 1. The effect of different wiping methods on the decontamination effect
[0054] Combined with the characteristics of decontamination of radioactively contaminated skin, it is not allowed to wipe back and forth, and it is not allowed to wipe from areas with high pollution to areas with low pollution. Therefore, the time and method of decontamination wet wipes and contaminated skin will have a greater impact on the decontamination effect. The wiping method is the same as 3 in Example 2. Unfold the decontamination wipes, lay them flat on the skin, squeeze them gently and then wipe them in one direction. See Table 2 for the effects of different squeezing times on the decontamination rate.

Abstract
The invention relates to the technical field of skin radioactive contamination treatment, and provides a decontamination wet tissue for radionuclide contaminated skin and application. The decontamination liquid is prepared from the following components in percentage by weight: 0.5 to 10 percent of disodium ethylene diamine tetraacetate, 0.5 to 10 percent of dimethyl(tetradecyl)amine oxide, 0.5 to 10 percent of sodium laureth sulfate, 0.5 to 10 percent of sodium bicarbonate, 0.1 to 10 percent of sodium alginate, 0.5 to 10 percent of phenoxyethanol and the balance of deionized water. The method for decontaminating the radionuclide contaminated skin comprises the following steps: step 1, unfolding a decontaminating wet tissue, flatly placing the decontaminating wet tissue on the skin, slightly squeezing the decontaminating wet tissue, wiping the skin from a low-pollution area to a high-pollution area in a single direction, folding the decontaminating wet tissue, wiping the skin by using a cleaning surface of the wet tissue, folding the decontaminating wet tissue again, and treating the decontaminating wet tissue in the same way; and step 2, repeating the step 1 on the same piece of skin by adopting three to four pieces of decontamination wet tissues in sequence to complete radionuclide decontamination treatment on the piece of skin.
Description
technical field [0001] The invention relates to the field of skin radioactive pollution treatment, in particular to a decontamination wet tissue for skin contaminated with radionuclides and a method for decontaminating skin by using the wet tissue. Background technique [0002] Personnel engaged in nuclear-related professions, such as the operation and maintenance of nuclear power plants and nuclear devices, or the public affected by nuclear accidents or nuclear leaks, may be contaminated by radioactivity on their body surfaces. If they cannot be removed in time, it will have a certain impact on the health of the personnel. [0003] A variety of decontamination products for removing radioactive contamination of the skin have been developed at home and abroad. Decontamination agents commonly used to remove radioactive substances include detergents, complexing agents, etc., which are usually formulated with water in a certain proportion to make a decontamination solution.
