Radon exposure in Egyptian tombs. Many ancient Egyptian tombs were cut from limestone rock that con- tained uranium. Since most tombs are not well-ventilated, guards, tour guides, and visitors may be exposed to deadly radon gas. In Radiation Protection Dosimetry (Dec. 2010), a study of radon exposure in tombs in the Valley of Kings, Luxor, Egypt (recently opened for public tours), was con- ducted. The radon levels-measured in becquerels per cubic meter (Bq/m³)–in the inner chambers of a sample of 12 tombs were determined. For this data, assume that f = 3,643 Bq/m³ and s = 1,187Bq/m³. Use this infor- mation to estimate, with 95% confidence, the true mean level of radon exposure in tombs in the Valley of Kings. Interpret the resulting interval.
