Radon Revisited

Invisible Gas Continues to Elude Scientists

In 1984, public concern over residential radon mounted when Stanley Watras set of radiation monitor alarms as he arrived for work at a Pennsylvania nuclear plant. When no explanation could be found at the pant, tests at the Watras home revealed radon levels about 800 times the federal standard. Three years later, the Environmental Protection Agency (EPA) declared indoor radon “the most deadly environmental hazard in the U.S.” – responsible for more cancer deaths than any other pollutant under its jurisdiction. The agency maintain that position today.
