This little sucker cost me a grand and a hole in my roof
Lots of bad information in this post. Mitigation is certainly not snake oil, and the accuracy of this device is well established, including the readings people have seen pre and post-mitigation efforts, mine included.

The rest of your argument is a claim that the US EPA standard is too aggressive, which is an entirely different discussion altogether, but does nothing to refute the accuracy of the device or whether mitigation actually works to reduce indoor radon levels (which again is well established.)

As for changing standards over time, we have plenty of evidence for how long it took for smoking to be considered as dangerous as it now is today. Some people are more likely to err on the side of caution while others prefer to throw caution to the wind. Regardless, if you are interested in checking indoor radon levels, this is a good device despite all your unsupported contentions to the contrary.

What kind of readings were you getting before you decided to do the radon mitigation?

Bought one of these back in December and it works great. I'll probably resell it once I've gotten a full year of readings

Most of the time it was around 3 or 4 but it did get to around 7 or 8

The biggest issue I had was that the numbers in the basement were actually the same as the rest of the house

What situations does it make sense to get this one instead of the $15 one use test kits?

I used a test kit 1-2 times a while back and I was on the border 4 level.

I'd say you need it because the $15 tests are really more like $40 if you want the results. How far apart were the 2 tests you ran? What season? So many variables that for the leave of mind this provides it's worth it especially if your short terms tests were borderline high.

For me I did 4 tests at home and said what a waste of money. Partially because the second and third ones I had to throw away due to a cat knocking one of the vials over and then working long hours and not being able to seal it up in time.

Winter time with everything closed up I was seeing almost 4 in the basement. I'm currently moving this thing around my house now room by room one week at a time. So far levels are really low everywhere else. I'll probably still do the mitigation eventually anyways

Please get one which can keep track of the data. The radon level depends on the weather if you have mitigation. When the ground freeze, the radon pump has to work harder to work.
Here one point per hour and you can see spike in the winter.

Yes you do, irrespective of the house built year. Especially if you have basement or crawl space. Just check your readings.

Just bought a home and skipped the overpriced radon test with the home inspection. Perfect timing, thanks and repped
