Radon Environmental has mapped all of Canada for radon, finding some of the highest readings in densely populated areas not far from the U.S. border.

Geoscience is the most important factor in radon presence, Whitehead says, explaining that uranium and thorium have been present in the earth’s crust since the formation of the planet. Common in Canada’s rocks, soil and groundwater, those elements moved with the glaciers into the United States over tens of thousands of years.

Present to some degree in all buildings, radon levels depend on myriad factors, including presence in water; uranium content of the

ground beneath the foundation; underlying

pathways in bedrock and soil for the gas to

travel; building design and materials; and

seasonal weather condition.

“This is why it is important for every building to be

tested,” Whitehead says. “One building is not like

another.”

Solutions available

While the bad news is some radon is always

indoors, the good news is it can be blocked

during construction, and detected and mitigated

in existing buildings.

Among Radon Environmental’s solutions is Radon

Guard, a structural, under-slab insulation and ventilation panel system that’s Canadian and U.S. building code compliant and, as a bonus, boosts LEED credits.

Then there’s Radostat, a smart device the size of a smoke detector that can be placed in basements, which are most prone to radon. Upon detecting a high reading, the system activates ventilation. Radostat also is less invasive to building design and prioritizes energy efficiency along with good indoor air quality.

And since groundwater may emit harmful gasses from faucets, shower heads and toilets, Radon Environmental has partnered with an Ontario company, Airwell Technologies, to aerate wells with a low-voltage compressor that expels radon and other volatile gases, like methane.

“If you’re on a well, and you have high indoor radon levels, 99 percent of the time your water will also be high in radon,” Whitehead says, adding that the risk isn’t from drinking, but from inhaling the gas.

No rising above radon

The same modern construction that provides for energy-efficient buildings can actually increase radon risk due to reduced air exchange, Whitehead warns. And while radon levels are most likely highest in the lower levels, the upper floors of tall structures don’t necessarily offer sanctuary. Air flow creates movement—the stack effect—that can make heavy gas rise up stairwells and elevator shafts.

Then there are the building materials. Whitehead tells of a seven-story Atlanta condominium with high radon levels throughout. The cause was finally found to be in the concrete walls that contained uranium-contaminated aggregate. The solution was installing air exchangers in the 300 units, lowering the radon levels below the EPA’s action level.

A man on a mission

For Whitehead, the mission of radon detection and mitigation grew somewhat naturally from previous positions in the chemical and mining industries in North America and Europe, where he established a reputation as a company builder.

Declining attractive offers to relocate to the U.S. or Europe, Whitehead stayed in Western Canada, opting to apply his experience in what seemed an unfilled niche that combined business opportunity with a greater good.

In the past decade, Radon Environmental has made itself heard, influencing Canadian building codes and stressing the need for testing and mitigation not just in the home, but in schools and workplaces. Having completed the first extensive geologic mapping of Canada, the company produced a continental map of North America and now offers radon mapping services to cities and municipalities.

Radon Environmental will participate in Boston’s Greenbuild International Conference and Expo convention this November, and that’ll give Whitehead the chance to stress again how prevalent the gas is in the Northeast. He’s encouraged that more and more U.S. states are opting for stringent radon testing and prevention measures for new and existing construction.

In Canada, he also gets out the word through his role as a founding member and president of the Canadian Association of Radon Scientists and Technologists (CARST) and with the help of such celebrities as Mike Holmes, whose TV show “Holmes Inspection” advises Canadians about renovation issues. Then there’s Whitehead’s role as a director of Cancer Survivors Against Radon (CanSAR), to which he has a very personal connection.

Hits close to home

When his family lived in Ottawa during the 1990s, Whitehead’s wife, Janet, ran an interior design business in their three-floor home. In 2011, long after the Whiteheads moved to British Columbia, Janet—a never-smoker—was diagnosed with lung cancer that forced the partial removal of her left lung and removal of tumors in her right lobes.

Vividly detailing her illness on Radon Environmental’s website, Janet says the radon level in the Ottawa house was 85 picocuries or 20 times the EPA action guideline in the U.S.

“I now worry about my husband and three children who were also exposed to this lethally high level of radiation, and I would encourage everyone to test their homes, schools and workplaces for radon,” she writes. “Lung cancer kills more people in North America than breast, colon and prostate cancer combined. Radon-induced lung cancer is totally preventable.”

Reminded again of the radon risk in Canada’s capital region, the Whiteheads sent the occupants of their former house a radon detector that initially was thought to be faulty since the reading was so high. Subsequent tests by a radon professional validated the high levels, and—at the Whiteheads’ urging—the occupants hired a contractor to mitigate the problem and consulted with their doctor.

To Alan Whitehead, it was one potentially troublesome situation solved, but with many, many more to go.
