Description

Technical Field

[0001] The utility model relates to the technical field of radon progeny purification, and more particularly to radon removal equipment. Background Art

[0002] Radon (Rn) is a colorless, odorless radioactive gas produced by the decay of radium (Ra) in nature. It usually exists in the air in its elemental form. It is chemically stable, and all its isotopes are radioactive. Radon decays in air, producing radon daughters. These daughters are charged and can attach to tiny airborne particles or deposit on surfaces. Most radon is excreted after inhalation. Radon daughters are positively charged metallic particles that easily lodge and deposit in the respiratory tract and lungs. Alpha particles produced by the decay of radon daughters can damage or alter the molecular structure of DNA in human cells, leading to abnormal cell division and ultimately lung cancer. Radon in residential buildings originates from building materials, rocks, and soil. Soil radon only affects basements and the first three floors of a building. High indoor radon concentrations can also be found in underground buildings, tunnels, and laboratories. Radon levels exceeding health standards pose a serious threat to human health. A high radon concentration means there is more radon present, and accordingly, more radon daughters are produced after the radon decays. Therefore, high radon concentrations are usually accompanied by high concentrations of radon daughters.

[0003] However, existing equipment for removing radon and its progeny only has corresponding devices for adsorbing and removing radon in the gas, but does not have the function of detecting radon. That is, workers are required to manually detect the concentration of radon and its progeny in a certain environment to determine whether to turn on the equipment to remove radon progeny. It is very easy for radon progeny to be removed in time or for workers to inhale radon progeny during the process of detecting concentration and turning on the equipment, resulting in casualties. In addition, after turning on the equipment, it is impossible to accurately know the radon content in the purified air, nor is it possible to know the specific purification time of the equipment. This can easily lead to insufficient purification or excessive purification time, which shortens the life of the equipment.

[0004] Therefore, how to provide a radon removal device that can automatically detect the concentration of radon gas and its daughters to automatically determine whether to perform a radon gas purification path is a problem that those skilled in the art urgently need to solve.
