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.
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.Read more ›
After a year of living there, I discovered indoor radon levels averaging 10pCi/L using a Safety Siren Pro. This was later verified with a second Safety Siren Pro, and re-verified with a Sun Nuclear, and several of the the First Alert Radon Gas Test Kits, based on the activated carbon. Available at Home Improvement stores.
EPA standards for radon is less than 4.0 pCi/L.
The landlord declined to investigate. EPA officials said that radon is largely "unregulated". Austin Tenant Council said the main recourse is either to move or sue. In the latter case, be prepared for an immediate 30-day move out notice in retaliation.
The house is built on a concrete slab, with majority ceramic tile and carpeting in the bedroom.
The Geiger counter is a Radalert Inspector, an expensive model with pancake detector that can detect alpha emitters. The radon gas detector is a Safety Siren Pro Series. The air filter is a Holmes HEPA that concentrates the dust carrying the radon gas particles. Radon is electrically charged, and will cling to dust, making the dust "hot".
Normal background radiation is roughly 50 CPS. At 6.5 pCi/L, running the air filter briefly will concentrate enough radiation to push the Geiger counter above 3600 CPM (counts per minute), 60 time background of 50 CPM.
Radon has a very short half life and the radiation measured off the air filter will drop fast once it is turned off.Read more ›
