EPA monitors the air for radiation to understand levels of natural background radiation. Following trends allows scientists to detect elevated levels so that scientists and officials can determine whether protective actions are required to safeguard the public. The RadNet system has been used to detect and track radioactive material associated with foreign atmospheric nuclear incidents such as the Chernobyl disaster in Ukraine and the accident at the Fukushima nuclear reactor incident in Japan.
