The documentation I got with my house showed a radon reading above 50.0 before a mitigation system was installed and < 4.0 after it was installed.
The radon mitigation fan broke and I falsely thought painting / sealing the basement floor (years ago) would stop the radon.
After plugging in this unit I got a reading (after a few days) around 10.0 and it went up day by day. I replaced the mitigation fan when the reading was around 20.0. This unit then showed the level go down each day (took about 2 weeks to get to safe level).
Highly recommend this considering you can spend $15.00 a pop on those radon testers you mail in. One I used said I had a safe level.

I bought this gizmo a few weeks ago to monitor the basement in our new house and see if it is usable as an entertainment/gym area. In the summer when we did the radon test the result came in at 2.4 . When I first turned on this device the result came in at 8.4 !!

That made me freak out a bit, but after re-reading the instruction I realized that placing the detector 2 feet away from the sump hole may not be the right thing to do. So, I moved it closer to the middle of the basement and reset it. After a couple of days the reading came in at 4.6 .

During heavy rains the device showed readings of as high as 5.9 and it went down to 4.2 during dry weather.

Before taking any drastic measures I decided to first do some common sense maintenance tasks on the basement to at least prevent radon from entering the living area upstairs. I taped up all the cracks in the HVAC ductwork that I could find. The radon reading slowly creeped up to 4.6 due to reduced ventilation of the basement, but at least none of it was going upstairs.

I called our house inspector who did the test and he pointed out that when we inspected the house there were storage cabinets over the sump hole and along the walls, covering up the "mother earth." So I placed a piece of rubber tile over the sump hole and the reading when down to 3.2 in a couple of days.

So, what's the moral of this story ? While I can't vouch for precision of this device I learned the following:

- You need to leave it on for at least a month before you get an accurate reading.
- There is no need to freak out over "mildly" high readings. First, the device is not that accurate. Professional continuous testing devices cost thousands. So, don't take what it says as an absolute measure. Trust, but verify.

I've had this detector for over 3 years now and it's true what they say about it needing calibration every year. This means sending the unit back to the manufacturer for service. If you don't, it tends to sneak up with progressively higher readings. Unfortunately, I found this out after I bought it. So here's the thing you will need to consider: you are paying $130 for 1 year of ballpark accuracy readings. After that it will cost you another $75 (+2 way S&H fee to Michigan) per year just to maintain the same reading accuracy. Seems like a high price to pay when you can have a professional come in yearly and give you a more accurate reading for about the same price. Granted, readings can change daily to weekly but in my three years of measuring, I've found that the detection range was pretty consistent (within 2-2.5 pCi/L seasonal differential). Now I have this $130 device that needs another $100 or so to make it semi-useful again.

I've been using two of these continuously for years in our basement. I thought we had a mild radon problem. Readings ranging from rare 3 to as high as 7 typically 4 or 5. But it didnt follow the usual seasonal pattern. At least in my area radon readings are usually highest in the winter. Yet our readings were lowest in the winter, highest in the summer.

Then on a hunch, I wondered if maybe humidity in the basement was making this read incorrectly. Humidity is much higher in the basement in the summer. I bought a dehumidifier a month ago and since then our readings have ranged from 2-3 usually 3. You must understand that in 5 years in this home we have never before seen a reading of 2 in the basement, and 3 has been as rare as a blue moon.

I'm not sure what to believe our radon level is anymore. I plan to do more charcoal tests and a long term test to better evaluate it.

The description of the item mentions something about humidity, but I haven't been able to find anything which describes a relationship between humidity levels and what this unit reads.

Update 12/2010: I should have updated a while ago. Back in 2008 I did several canister tests both short and long term. In general the short term canister tests (several) did match the results from the device fairly closely. I then went ahead and had the radon mitigated and performed radon tests before and after. Again the results match reasonably closely. After mitigation, my unit shows a reading of 1.2-1.8 while the expensive calibrated official test shows readings around 0.6-0.8. In either case mitigation has made the level apparently safe for me although my electric bill has gone up more than expected.

Though the interface is a bit clunky the device really works great!
I would never again bother with those mail-in radon detectors again -- save to validate the machine -- as our device's values were shown to be the same. But, unlike those mail-in cans the results are delivered within the two days (the device needs that amount of time to calculate a moving average) instead of a month.
Thanks to the device I was warned of a 4.5 pico curie level in my basement. After having a radon mitigation system installed, the device showed the level dropping to 1.6.
A friend of mine, more out of curiosity, asked to borrow the device. He put it in his basement expecting nothing much. A few days later he heard a fire-alarm like siren coming from the basement. He'd forgotten about the detector. When he finally realized it was the radon detector he was shocked to find his basement had a radon level of 13! Now, he too has a radon mitigation system and the levels have dropped to around 1.0.
We calculated that we reduced our families' lung cancer mortality rates by multiples -- especially for my son whose lungs are more sensitive.

"...Mortality rate is usually expressed as deaths/100 over a lifetime of exposure (70 years 75% of the time). Does not tell you when the deaths occurred, just an estimate of how many.

4 pci/liter: 3% average mortality (e.g. 3 out of 100 people expected to die of lung cancer)
15 pci/liter: 10% average
20 pci/liter: 15% average mortality
200 pci/liter: 50% average mortality

Houses with upwards of 2000 pci/liter have been measured! Even these can be dangerous in the short term (10 years or less). Although these mortality rates seem very high, they are similar with those for things we accept as part of our everyday lives.
