The community was named for a green riverbank near the original town site.[4]
National Radio Quiet Zone
Green Bank is located within the National Radio Quiet Zone, which means that radio transmissions are heavily restricted by law.[5] This policy is enforced by a "radio policeman" who uses specialized equipment to detect signals from unauthorized electronics.[6] Green Bank is home to the Green Bank Telescope, the world's largest fully steerable radio telescope, which was operated by the National Radio Astronomy Observatory (NRAO) until September 30, 2016. Since October 1, 2016, the Telescope has been operated by the Green Bank Observatory, which is no longer part of the NRAO. It was at the Green Bank Site in 1961 that Frank Drake presented the Drake Equation, which was developed to provide an estimate of the total number of detectable extraterrestrial civilizations in the Milky Way galaxy.
As Green Bank is located within the National Radio Quiet Zone, many people who believe they suffer from electromagnetic hypersensitivity, a disputed medical condition, are finding new homes within its borders.[7] Escape from cellular radiation is the main attraction to Green Bank for these people. As of 2013[update], around 30 people had moved to Green Bank to escape the supposed effects of electromagnetic hypersensitivity.[8]
