There may be gas in your home causing lung cancer. Here's what to do about it
CBC
You can't see it, you can't smell it and you can't taste it — and it's the No. 1 cause of lung cancer for non-smokers.
Radon is a natural radioactive gas that comes from the ground. It isn't a problem when it's released into the air outside, but it's dangerous when trapped inside our homes.
Last winter, 110 homes in Conception Bay South were tested for radon gas, and 30 per cent of them had levels above Health Canada's guidelines.
"It was a little bit of a surprise, maybe because we didn't know a lot about it," said Deputy Mayor Andrea Gosse. "But since that time we've become more educated and we want our community more educated."
Now municipalities in Newfoundland and Labrador — including C.B.S. and Mount Pearl — will take part in November in what's called Radon Action Month.
The municipalities are encouraging residents to test their homes for radon, and are providing free test kits from the Health Canada-funded Take Action on Radon campaign.
The test is a small device that you place in your home, at the lowest lived-in level. After 91 days, you put in an envelope and send it to a lab to be tested.
"Simple. It's like it's like an ant trap," said Gosse. "Nothing to do, nothing to monitor. I even forgot it was in the house until I got my e-mail and said, oh, I've got to put that together now and send it in."
Gosse said there is no reason not to find out if your home contains radon.
"It's a proactive measure and a very simple … I would recommend, you know, residents take part."
Conception Bay South has more test kits on the way, and Mount Pearl distributed all 400 of its kits within hours of publicizing them.
Consumers can buy their own tests in stores, but not all are recommended by local experts.
For instance, CBC went to a Home Depot store to see what radon test kits are available, and found Pro-lab's Long-Term Radon Gas Test Kit.
However, Pam Warkentin, Take Action on Radon's executive director, says this test is not on the Canadian National Radon Proficiency Program's list of providers. She said customer feedback demonstrated it doesn't properly report radon levels. The lab for the test kit is also in the U.S., which she said has caused issues with timely testing.
Indigenous communities throughout B.C. are mourning the death of former premier John Horgan, a man who many knew long before he began his career in politics.
A group of former leaders and climate experts say the annual UN COP climate talks are no longer fit for purpose and need to be reformed, publishing a critical open letter mid-way through what has so far been a fractious summit.

A decision over how the provincial government regulates moose hunting in a First Nation's traditional territory now rests with a Manitoba judge, whose ruling will be precedent-setting, lawyers in the case say.
A teenager diagnosed with bird flu in British Columbia is the first domestically acquired human case of H5N1 avian influenza, the Public Health Agency of Canada says.
The Manitoba government made a "political compromise" in its decision to issue a reduced number of moose hunting licences to non-Indigenous hunters in northern parts of the province earlier this year, a lawyer representing a First Nation in the area has argued in court.
If it weren't for a stem cell transplant — less than half a cup of blood from a stranger's umbilical cord — four-year-old Tristan Ford would almost certainly have died as an infant, his parents say.
A Métis saddle from the early 1800s is at the centre of an exhibit that opened last month at a Swiss museum, along with contemporary beadwork created by other Red River Métis artists.
A dome-shaped device floating in Halifax's Northwest Arm could easily be confused with a buoy, but it is actually a contraption meant to turn ocean water into fresh water.
As of Tuesday, there are limits on the number of bottles of spirits a person can buy at the B.C. Liquor store in Tofino, a move that leaders of the Ahousaht First Nation were pushing for.
