Problems solved by technology

[0002] The uranium tailings stacked on the surface of the tailings pool is an important source of radon. Due to the thunderstorm weather and the magnetic storm caused by the radiation of the solar particle stream, the tailings stacked on the surface are affected by the geoelectric field, and the geoelectric field will affect the radon progeny in the pores of the tailings. The migration of daughters, the migration of daughters will inevitably affect the migration of radon in the pores of tailings. However, the existing technologies and devices only develop electrostatic radon daughter removal devices, and there is no specific occurrence of radon removal devices under the combined effects of voltage, temperature and wind pressure.
