What this data can and can’t tell you
- Radon is a survey. The radon share comes from about 14,000 long-term home tests in 2009–2011, pooled for now by the 2007 health region Lac La Ronge 156 sits in.
- Earthquakes are modelled. NRCan models what earthquakes would cost buildings each year on average, subdivision by subdivision; Lac La Ronge 156’s figure is its subdivision’s.
- Wildfire counts one way. Wildfire is read from the national burned-area record around Lac La Ronge 156’s homes since 1986, a history of fire that may lower Risk but never raises it.
- Flood studies aren’t flood zones. A study’s area can be a whole watershed or province, so being on the inventory says a map exists, not that a home in Lac La Ronge 156 floods.
