The RadNet system is the only nationwide monitoring network that provides continuous measurements of radiation levels across the United States during normal and emergency conditions. RadNet monitoring station locations were selected to provide optimum population and geographical coverage throughout the United States. Stations are widely dispersed throughout the nation, covering all states, Puerto Rico and the District of Columbia. Most major population centers in the United States have a fixed RadNet air monitor.
