Abstract

The invention belongs to the technical field of experimental devices, and discloses a device and a method for measuring uranium migration in small column simulated soil. The device for measuring uranium migration in small column simulated soil is provided with a simulated soil gas heating unit, a gas circulating pump and one or more simulated soil medium units; the simulated soil gas heating unitis provided with a PVC pipe, a disturbance fan is installed in the PVC pipe, an upper pipe cover is installed at the upper end of the PVC pipe in a buckled mode, a lower pipe cover is installed at thelower end of the PVC pipe in a buckled mode, and an electric heating wire is installed in the lower pipe cover; and the soil medium simulation unit is provided with a PVC pipe, the PVC pipe is filledwith a uniform rock-soil medium, the bottom end of the rock-soil medium is filled with a uranium-containing base material, the upper end of the rock-soil medium is provided with an upper pipe cover in a buckled mode, and the lower end of the rock-soil medium is provided with a lower pipe cover in a buckled mode. When the device is used, the uranium element can penetrate through the rock-soil medium in the model, so that the observable uranium content is formed in the sampling gas in the PVC pipe at the upper end of the rock-soil medium, and the original observation time is greatly shortened.

Description

technical field [0001] The invention belongs to the technical field of experimental devices, in particular to a device and method for measuring uranium migration in small column simulated soil. Background technique [0002] Uranium is a natural radioactive element and is currently the most important nuclear material. During the application of nuclear energy and nuclear technology, it may diffuse into the environment, and after migration and deposition, it will pollute the soil and endanger human health. Due to the complexity of the medium environment and fluid environment in the actual soil, it is difficult to study the migration of uranium in the soil, and it is impossible to accurately understand the conditions that affect the migration of uranium nuclides. At the same time, the migration of uranium in soil is a long-term and slow process, and it is difficult to observe the distribution changes of uranium in a wide range of soil media in a short period of time.
