The Environmental Protection Agency acknowledges that radon, the radioactive gas caused by the disintegration of radium, is a significant problem, and recommends that all homes nationwide be tested. Homes constructed near bedrock have a potentially high risk because water flows through contaminated ground, thereby producing the gas through steam in showering or other use of hot water. EPA standards for radon levels allow four picocuries of radon per liter of air. Area homes average less than one picocurie. The test consists of placing a noiseless machine in the home for 24 hours.
Homeowners usually receive a report within a week.
Because testing is meant only to detect possible problems, if high levels are found, the group directs homeowners to a professional lab for more tests. Ways to correct high levels of radon include sealing cracks, venting, and various methods of collecting and venting the gas. According to Bob Matheson, a senior majoring in hazardous waste management, microwave testing is valuable for peace of mind that radiation is not being emitted from the appliance. He added that although most microwaves are free from leaks, even new ones that have been damaged in shipping have the potential of leaks. All microwaves free of debris can be tested by the group with a simple procedure taking only minutes.
