Wow! Hopefully I see results that good.

Great until you see your neighbour flying through the neighborhood while shooting laser from his eyes, while you're struggling to open a jar.

did they have a basement, i wonder a person i know thier cousin had lung cancer was from it and passed away in late 2000s, they dint have basement though, but he was HOME all day, never truly launched so to speak but he worked jobs though. not a smoker, cant be cleaning chemicals.

Came here to say this. If there is a leak after the fan, radon will be pumped into the dwelling. Fan should be outside or in vented attic. Exhaust vent must be away windows or vent-intakes and above roofline. Minimum clearances vary with jurisdiction. But it's generally a bad idea to put the fan in-doors.

Fans must be placed outside because a leak after the fan can be bad. Now in all honesty, that only holds true if you have bends and twists and turns. I personally think you can place it in a basement or attic as long as you have a straight continuous pipe going up.

As bonus you get passive suction when the pipe is warm.

My fan is outside in Minnesota. I made it a contingent on buying since the seller didn't want to budge on price.

$1000-$2000

Mine was $3031 CAD to have it professionally installed and certified.

Depends on many factors. If there's an available sump pump, a radon lid is around $150. A fan is around $150. Between $100 and $300 for pvc, depending on number of elbows and distance. Assuming an open electrical breaker is available, and again depending on distance, $100 to $200 for electrical. $15 for a manometer. $20 for pvc cleaner and cement. $5 for tube of acrylic caulking. Total for parts, assume $500 to $850.

Wothout a sump well, save $150 on lid, but x3 or x4 the pvc. Roughly $300 to $1000. Rental of a Hilti and diamond holesaw bit to add vents to corners of slab. So maybe $300 or so. Total around $600 to $1500, give or take.

This is just parts. Labor will be $1k to $4k depending on location and complexity. If you can do it yourself, it's a significant savings. With an available sump well, it's an easy to medium difficulty project. Without one, it gets significantly more complicated.

“Radon comes from the natural radioactive breakdown of uranium and thorium found in the earth's soil, rock, and groundwater. As these elements decay over time, they turn into radium and then release radon gas, which seeps up through the ground and can get trapped inside buildings.”

So, a natural radioactive gas that seeps into the house through the foundation. The mitigation system puts a vacuum under the basement concrete slab and vents it outside.

Very common in Canada. All new construction is required to have a port already installed in the slab to install a system.

It comes out of the ground. It's more prevalent in certain areas. It accumulates in basements and crawl spaces and can cause lung cancer from long term exposure.

it comes from the ground usually from decaying sources, like uranium or other heavy elements.

Put a pipe into the space under the foundation of the house. It's not a huge void, but whatever space is there will have a mix of normal air and gases like radon.

Hook up a fan to the pipe. It pulls gas out of that space, pushing the radon out into the yard where it can dissipate into the neighborhood instead of reaching a higher concentration inside your house.

Hmm, I wonder if new builds have radon-collection trenches dug before they pour the foundation. It would make sense vs. retrofitting a fan system, but it would add some cost for the extra digging and making sure you don't just fill the mini trenches with your concrete pour.
