The corresponding element of radon is radon gas, which is colorless, odorless and tasteless inert gas with radioactivity. The chemical property of radon is not active and it is not easy to form compounds. Radon has no known biological effects. Because radon is a radioactive gas, when inhaled into the body, the alpha particles of radon decay can cause radiation damage to the respiratory system of people and cause lung cancer. Building materials are the main source of indoor radon. Such as granite, brick sand, cement and gypsum, especially natural stones containing radioactive elements, are most likely to release radon. Feature: This radon sensor is a radon gas measuring sensor. The time required to display the effect is only 1 hour, while the time for other foreign popular devices is 24 to 48 hours, with an uncertainty of less than 15%. Application: This radon sensor can be applied to various products, such as air quality display device, air purifier, indoor air conditioner, ventilation fan and ventilation system, with high sensitivity of 0.30cpm/pCi/L.
