Map showing radon potential of rocks and soils in Fairfax County, Virginia
James K. Otton, R. Randall Schumann, Douglass E. Owen, Nelson Thurman, Joseph S. Duval
1988, Miscellaneous Field Studies Map 2047
Since 1984, indoor radon has gained national attention as a significant health hazard in the United States. Radon is a colorless, odorless, radioactive gas derived from uranium by radioactive decay. The U.S. Environmental Protection Agency (EPA) now projects that 5,000 to 20,000 lung-cancer deaths per year may be attributed to...
