Description

Detection device for indoor radon

Technical Field

The utility model relates to the technical field of radon detection, in particular to a detection device for indoor radon.

Background

Radon (Radon), also known as , is a chemical element, denoted Rn. The simple substance corresponding to radon is radon which is colorless, odorless and tasteless inert gas and has radioactivity. Radon is chemically inert and does not readily form compounds. Radon has no known biological effects. Because radon is a radioactive gas, when a person inhales into the body, alpha particles of the radon which decay can cause radiation damage in the respiratory system of the person, and lung cancer is caused. And building materials are the most major source of radon in rooms. Such as granite, brick sand, cement and gypsum, and especially natural stone containing radioactive elements, are most likely to release radon.

Radon daughters are electrically charged, which allows them to adhere to the surface of the aerosol particles. They also remain unattached and deposit onto building surfaces, thereby reducing exposure. Experiments have shown that the percentage of radon daughter volume deposited on the building surface to total radon daughter is a function of aerosol particle concentration. When the aerosol particle concentration is more than 105/cm 3, the radon daughter deposited on the surface of the building accounts for 4% of the total radon daughter; and when the concentration of aerosol particles is less than 103/cm 3, the ratio is 86%. Observations have also shown that radon daughters are deposited on wall surfaces with a higher capacity than floors and counter tops of indoor objects.

In view of the above-mentioned related technologies, the inventor believes that in the prior art, the detection of radon daughter can only detect radon gas in the air, and radon daughter deposited on the wall surface is difficult to detect, which has a certain potential safety hazard.
