In addition, studies in Europe, North America and China have confirmed that even low concentrations of radon such as those commonly found in residential settings also pose health risks and contribute to the occurrence of lung cancers worldwide. Information about where radon is most common in Washington, along with lung cancer and smoking rates for those areas, is available on the Washington Tracking Network (WTN). Not much research has been carried out on radon, due to its radioactivity, but it is largely un-reactive with few known compounds. Radon is estimated to cause between 3% to 14% of all lung cancers in a country, depending on the national average radon level and smoking prevalence. These blocks are named for the characteristic spectra they produce: sharp (s), principal (p), diffuse (d), and fundamental (f). Radon Information. As we breathe, these particles are deposited on the cells lining the airways, where they can damage DNA and potentially cause lung cancer. It is given by the ratio of the pressure on a body to the fractional decrease in volume.
