The Safety Siren Pro4 Radon Gas Detector with digital LCD display continuously monitors Radon Gas with 3 alarm modes that alerts you to protect your family from lung cancer from radon gas exposure. The device is not a single use radon test kit, this unit performs continuous radon gas monitoring. The display shows short and long-term radon level averages. After 48 hs of sampling the unit provides the first radon reading. Radon gas in air or water is a health hazard resulting from uranium breaking down in soil. Radon is a radioactive gas that is colorless, odorless, and tasteless and is impossible to detect without sensitive test equipment. Radon gas rises through the soil and seep through cracks, holes and drain pipes in the foundation or basement. Continuous radon monitoring is recommended in high radon areas or when radon mitigation systems are used. Radon gas levels change based on humidity and season. Health Canada suggests that corrective action be taken to reduce radon levels over 200 Bq/m3.
