More Radon Testing for Public Buildings

The second round of testing for radon gas, part of a five-year program, is underway for almost 2,000 public buildings.

Public housing, schools, health care facilities and provincial buildings are among the buildings selected for testing as part of the province's efforts to comply with the new national guideline for radon in indoor air, announced in February 2007.

Pat Wall, chair of the interdepartmental advisory group on radon said tests are being conducted as part of the province's proactive approach to radon management.

"Nova Scotia is leading most of Canada with our testing program and public awareness on this important health issue," said Mr. Wall. "We want to be sure that public buildings meet the guideline and that homeowners are aware they should test their homes for radon."

Dr. Robert Strang, chief public health officer, said students and staff in public buildings are not at risk for short-term health concerns, but emphasized the need for Nova Scotians to test their homes.

"A lifetime exposure to high levels of radon can lead to an increased risk of lung cancer, especially for smokers," said Dr. Strang.

Radon is a naturally occurring, odourless and colourless radioactive soil gas that is the leading cause of lung cancer in non-smokers. The risk of lung cancer increases when people are exposed to high levels over a lifetime. Radon does not pose an immediate health risk. Typically, radon seeps into buildings through cracks and openings in foundations.

Whether a nearby building tests below the national radon exposure guideline, all property owners are encouraged to test their homes or buildings, and to reduce radon levels where necessary. Radon concentrations can vary between neighbouring properties. In large buildings it can also vary from room to room.
