A Glowing Report
The granite in New York City's Grand Central Station gives off more radiation than is allowed in public areas of a nuclear power plant. Granite is a hard crystalline igneous rock often used as a building material. It forms when magma cools slowly beneath the Earth's surface. Granite is made up of quartz and feldspar with minor amounts of mica, amphibole, and other minerals that may include uranium. The pink granite colonnaded Grand Central Station was inspired by the Roman baths of Caracalla. Grand Central Station was conceived to deal with congestion and opened for business on February 1, 1913. The lovely pink granite has a higher than average uranium content.
