The invention discloses an automatic concentration device for water radionuclides. The device comprises a concentration bottle, a heating device, a vacuum pump, a condensation circulating system, a detection assembly and a control assembly, wherein the concentration bottle is used for enriching and concentrating sample solution; the vacuum pump is used for providing negative pressure for the device; the condensation circulating system is used for carrying out heat exchange with the steam of the device under the negative pressure; the detection assembly is used for acquiring the current data related to concentration; and the control assembly is used for controlling the concentration bottle and the condensation circulating system according to the current data so as to obtain concentrated water radionuclides. The device is capable of realizing automation, ensuring the consistency of the enrichment and effectively solving the problems that the present water radionuclide enrichment speed islow and the data consistency of the processing process of the same batch is relatively bad.
Description
technical field [0001] The invention relates to the technical field of radionuclides, in particular to an automatic enrichment device for radionuclides in water bodies. Background technique [0002] With the development of nuclear energy and the peaceful use of nuclear energy, the waste water produced in the production process has increased, and the threat to environmental water bodies has continued to rise. In order to ensure the safe discharge of industrial production wastewater and the quality of drinking water sources, radioactive measurement of water bodies is an important task related to the national economy and people's livelihood. Radioactivity measurements in water bodies are generally carried out step by step, such as figure 1 As shown, first measure the total α and total β, and if the total α and total β do not exceed the standard, the water is considered safe and can be drunk. When the total α and total β exceed the standard, it is necessary to measure the spec...
