Problems solved by technology

The method of enriching trace radioactivity in water by evaporation, co-precipitation, and resin method takes a long time and cannot meet the requirements of rapid measurement. Moreover, these methods are currently difficult to automate, and the entire process is extremely dependent on the technical level of personnel. Leads to poor consistency in enriched samples

Abstract

The invention discloses a radioactive nuclide enrichment method and device, and a system with same. The method comprises steps of collecting to-be-tested liquid, and controlling flow of the to-be-tested liquid; in the process of concentration and enrichment, heating and stirring to evaporate the to-be-tested liquid according to a preset target temperature difference and a target boiling heat transfer requirement, so as to enable evaporation speed to meet preset speed; after cleaning, collecting concentrated solution after enrichment of the radioactive nuclide, and obtaining a radioactive nuclide enrichment result of the to-be-tested liquid according to the concentrated solution. In the prior art, enrichment takes long time and is slow in speed, enrichment relies on technical level of an operator, and data of the same batch of processing is less consistent. The method solves the above technical problems. The vacuum, low-temperature enrichment method shortens enrichment time greatly, enables automatic operation, makes enriched samples more consistent, and is easy to implement.

Description

technical field [0001] The invention relates to the technical field of radionuclide detection, in particular to a radionuclide enrichment method, device and system with the same. 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. In the case of total α and total β exceeding the standard, it is necessary...
