The invention relates to an actinide nuclide body surface pollution decontamination decontaminating liquid and a preparation method thereof. The decontamination liquid is prepared from the following raw materials in parts by weight: 650 to 750 parts of ultrapure water, 70 to 80 parts of pentasodium diethylene triamine pentaacetate, 1 to 3 parts of diethylene triamine penta (methylene phosphonic acid), 30 to 40 parts of disodium ethylene diamine tetraacetate, 15 to 25 parts of tetrasodium 1-hydroxyethylidene-1, 1-diphosphonic acid, 60 to 70 parts of sodium alcohol ether sulphate, 25 to 35 parts of lauryl amide propyl ammonium oxide, 10 to 20 parts of fatty alcohol-polyoxyethylene ether 9, 40 to 50 parts of glycerol and 2, 3-diphosphonic acid. The removal rate of the prepared decontaminating and decontaminating liquid for the surface contamination of the actinide nuclides within 5-10 minutes on the surface contamination of the actinide nuclides can reach that 95.7% of uranium and 99% of thorium are removed from
