B.C. scientist suspects Sea-to-Sky, North Shore could be home to high-risk radon

A open health researcher says radon bearing on Vancouver’s North Shore and a Sea-to-Sky mezzanine is a intensity health jeopardy and she wants a B.C. supervision to change provincial building codes to simulate a risk. 

Anne-Marie Nicol, a open health researcher, is handing out giveaway radon exam kits to residents in a segment as partial of a citizen scholarship plan at Simon Fraser University. The tests take 91 days to complete and Nicol says she expects a results will infer a range should re-categorize a area as carrying high radon potential.

The B.C. Building Code separates a range into dual areas formed on their intensity for radon exposure. Radon Area 1 is easterly of a Coast Mountains and covers a Interior of a province. Radon Area 2 covers all west of a mountains.

Radon gas forms when uranium erodes into a soil. People vital in homes built on tip of infested dirt are during risk since a hot gas can trickle inside.

According to Health Canada, radon kills 3,200 Canadians a year and is a second heading means of lung cancer after smoking.

Under a stream building code, all new buildings in Area 1, easterly of a Coast Mountains that includes a Interior, contingency have a opening siren commissioned to pierce radon gas out of a structure. There is no opening requirement in Area 2, all west of a mountains, since it is deliberate a low radon intensity region.

Nicol says the Coast Mountains are abounding in uranium and this creates a ideal conditions for intensity radon poisoning.

“North and West Vancouver and a Sea-to-Sky seem to have aloft levels of uranium in a belligerent and they demeanour a lot some-more like a Interior than a rest of Vancouver,” Nicol said.

High-risk homes

A becquerel is the section scientists use to magnitude radioactivity. Health Canada says radon measurements aloft than 200 becquerels per cubic metre (200 Bq/m3) are a health risk.

Alan Whitehead, a boss of Radon Environment Management Corp., tests homes for radon from Whistler to North Vancouver. 

In a final 3 years, Whitehead says he has found radon levels between 600 Bq/m3 and 1,000 Bq/m3 in 4 West Vancouver homes.

Whitehead says during slightest 12 North Vancouver homes also tested above Health Canada reserve levels.

“New homes mostly have a problem since they are constructed with appetite charge in mind. They are tighter and have reduction ventilation, formulating a ideal charge for a rave of radon gas,” pronounced Whitehead.

Whitehead wants a Area 1 building formula practical provincewide

“You can’t strengthen one organisation of adults and not another when we know there is a intensity health hazard,” pronounced Whitehead.

Change could come

The B.C. government is proposing changes to a building formula and is seeking open feedback until Feb. 28.

“There is new justification of radon in buildings in areas that were before not famous to have towering levels of radon,” pronounced a Ministry of Municipal Affairs and Housing in a statement.

The due changes would make municipalities in Area 2 obliged for substantiating their possess radon information and last if radon vents should be mandatory.

Whitehead says this is a mistake.

“You don’t wish people who don’t know [the problem] to try and establish if they have a metropolitan problem. It’s a health risk.”

Get tested

Nicol will be during a North Vancouver City Library on Friday, Feb. 23 from 4 to 6 p.m. PT giving away test kits.

“We need people to be intent and researching a radon gas levels in their homes,” pronounced Nicol.

“I’m anticipating we can collect adequate justification from people’s homes to surprise building formula changes.”
