Scientists mapping deadly radon in calgary _ calgary herald

“One in five (homes) are over the maximum acceptable limit. Gas emoji That’s quite high and very surprising,” said Aaron Goodarzi, an assistant professor at U of C’s Arnie Charbonneau Cancer Institute. Z gas station He is spearheading a project to collect data to map the prevalence of the cancer-causing gas. Kansas gas service login So far, the team has tested 268 homes and aims to have 1,000 homeowners enrolled by the end of January.

Calgary’s early results are even more concerning if measured against U.S. Electricity deregulation wikipedia guidelines and those issued by the World Health Organization, which are more stringent.

Health Canada sets an acceptable annual rate of 200 becquerels per cubic metre (200 Bq/m3), while the U.S. Gas prices map rate is 150 and the World Health Organization has proposed recommended levels of 100. Electricity generation in california The term describes how many radioactive radon particles are decaying every second in every cubic metre of air.

“In Canada, we have a higher limit on what’s acceptable,” said Goodarzi. Ortega y gasset “I guess Health Canada feels Canadians have a higher tolerance for radon gas.”

Radon is the the second-leading cause of lung cancer in Canada, accounting for about 16 per cent of cases or 1,900 deaths per year. Npower electricity power cut Scientific studies have linked the risk of developing lung cancer to prolonged exposure to high levels of radon gas. Year 6 electricity A 2009-11 national study of 14,000 homes showed more than 1,500 had unacceptable levels.

Levels have reached as high as 4,000 Bq/m3 in Calgary homes, says Karin Dumais, president of Radon West, which has partnered with Goodarzi to provide test kits to homeowners and the corresponding data to the scientists.

“The highest level we’ve seen was 4,300 in B.C. Gas oil mix ratio chart In Calgary, it was 4,000. K gas station jobs They had poured concrete for the basement but not under the furnace so it was sucking air in from under the house. Gas upper stomach It was basically a radon distribution system.”

Radon is a naturally occurring gas produced from the radioactive decay of uranium in rocks and soil. Electricity voltage in paris It is colourless, odourless and tasteless. Cheapest gas in texas It is extremely prevalent in the Canadian prairies having been deposited by glaciers. Gas utility bill It seeps into homes through cracks in walls, floors and foundations and through floor drains and sumps. Houses in cold climates are at particular risk since windows and doors are kept closed for over half the year and there’s often little air circulation, which creates a vacuum effect.

A unique aspect of radon is the randomness of it. Electricity usage Dumais said one house she tested had levels of 1,000 Bq/m3 — five times the recommended level. Electricity transmission loss But a measurement 2.5 metres away was only 60.

Dumais got interested in radon when she built a net-zero energy home south of Okotoks and tested it. Gas 2015 She was shocked to see such high results in that type of home. 3 gases that cause global warming She passed the tester around to family and friends — all had levels higher than Canadian guidelines.

“A neighbour had 1,000, my parents were 780 and my sister was at 2,400. Her levels are equal to having 4,320 dental X-rays per year per person. Electricity 1800s Those are really dangerous levels.”

“It’s been known to the scientific community since the 1970s. Gas bubble in back But it really does take a local champion to raise the alarm,” said Goodarzi. “In the U.S., the Environmental Protection Agency has taken that step. In Canada, it’s a bit more complicated.”

Because radon is a naturally occurring element from the ground, it falls under provincial jurisdiction. Health Canada cannot mandate testing.

“British Columbia has a lower incidence rate but is way farther ahead than Alberta. Electricity human body Manitoba, with higher rates, is also farther ahead. Gas up asheville They have local champions. A gaseous mixture contains It needs to get on the radar of the federal government.”

In Health Canada’s national testing, it found the incidence rate in Alberta was 6.6 per cent. Gas vs diesel cars But only 23 homes were tested in Calgary, eight in Cochrane and one each in Okotoks and Airdrie.

“That’s why Dr. M gasbuddy Goodarzi’s research is so important,” said Dumais. Electricity voltage in china “There isn’t enough data out there to say for certain how big the problem is. Q gas station cleveland ohio If he gets enough data and can bring it to Alberta Health, perhaps it can act on it. Wd gaster theme We really need to start educating people.”

When Health Canada tested in Castlegar, B.C., it determined 29 per cent of homes there have radon. Electricity vocabulary words But when wider testing was done, the incidence rate shot up to 59 per cent.

Dana Schmidt was one of the unlucky ones living with the deadly gas in the West Kootenay city. His previously healthy wife died of lung cancer in 2009 and he went looking for answers. Gas relief while pregnant Their house, in which they had lived for 15 years, had radon levels twice the recommended guideline.

He set up the Donna Schmidt Memorial Lung Cancer Prevention Society and sent out radon test kits. Gasbuddy app Of the thousands of results received, 44 per cent were above the guidelines. Electricity symbols worksheet One home in the city registered at 600 times the acceptable limit.

Schmidt has a Phd in toxicology and worked in air quality control, but even he was unaware of how bad the problem is. Kansas gas service bill pay With his society, he is hoping to spread the word and prevent more deaths related to radon exposure.

“Even if we make a 10 per cent difference, that means (people are) saved. La gasolina daddy yankee mp3 People don’t have to go through premature death from lung cancer. Electricity around the world When you look at the health costs and the human misery caused, it matters.”

Some groups have lobbied for mandatory testing to be included in all Canadian real estate transactions and Health Canada considered it but abandoned the idea after concerns were raised by the Canadian Real Estate Association. Gasoline p Many states in the U.S. Electricity merit badge worksheet where radon is a problem, such as Montana, do have mandatory testing included in resale home deals.

New homes are also being looked at in terms of legislation. U gas hampton Since December 2014, the B.C. Electricity receiver definition Building Code provisions for the rough-in of a subfloor depressurization system now require installation of a radon vent pipe which extends through, and terminates outside, the building. Youtube gas laws The Alberta Building Code was also updated as of Nov. Electricity lab activities 1, 2015, to include radon mitigation.

Modifying a house to lower radon levels is relatively inexpensive, generally in the range of $2,000 to $2,500. Electricity and magnetism online games It usually involves changing the home’s negative pressure to positive by installing a pipe through the basement floor with a fan attached to draw the radon out.

“Our biggest message is that it’s fixable and you only know you have it if you test for it,” said Dumais. “It’s cheaper and easier to fix than asbestos but more dangerous.”

Goodarzi’s study aims to have 1,000 homes signed up for testing by Jan. Gas out game commercial 30 and finish by April.

“We’re hoping to catch as many as we can. (At the institute) we’re getting people coming in every day with lung cancer who have never smoked. Current electricity definition physics It’s primarily because of radon gas.”
