Digital Continuous Radon Gas Monitoring with Home Radon Alarm Protect your family from lung cancer from radon gas exposure with the only EPA evaluated radon gas alarm, the Safety Siren Pro 3 Electronic Radon Gas Detector from Family Safety Products. As seen on TV, this is not like a single use radon test detection kit: this digital radon gas monitor for home testing is a continuous radon tester that performs continuous radon gas monitoring. The clear, easily read digital radon level display shows short-term radon levels as well as long-term radon level averages. The Safety Siren electronic radon monitor gives its first radon reading after 48 hours of radon gas sampling. Radon gas in air or water is a health hazard resulting from uranium breaking down in soil. Exposure to radon can cause lung cancer. Continuous home radon monitoring is recommended in high radon areas or when radon mitigation systems are used. Radon gas levels change according to humidity and season. See in.Radon Facts in. below the radon monitor information. Family Safety Products' Electronic Radon Meter Features: USA EPA Evaluated.

- Great product for long term testing
Radon levels very depending on the temperature, humidity and the air pressure. EPA recommends a test that lasts ONE YEAR to determine the radon levels in your house. The charcoal canisters are a short term test and may give inaccurate results depending on the weather factors. Our unit has been in place for six months. Levels varied from 4 to 16 over the first month. After encapsulating the crawlspaces (DIY) the levels have fallen to 1.8 to 3.5. When there is a low pressure system in the area the readings go up and return to a lower level as a high pressure system moves in. If you encapsulate use a 10 or 15 mil product not 6 mil polyethylene. The heavier material provides a significantly better reduction in radon. ...more info
- Good company to deal with
I ordered this product as a Christmas present but it was not delivered on time due to a mishap at UPS and no fault of Best Quality Supplies. They were in contact with me night and day to ensure I was aware of the situation. They are a quality organization that care for their customer. I would order from them again.
- Radon det
Works great and confirmed a test I had 3 months ago by a local firm.
Update: Almost 2 years into owning this product and still working good. I have loaned it to others in our area who have had professional firms test their basements and it is confirming their results. So far so good....more info
- Radon Detector, safety siren pro 3
Safety Siren Pro 3 Radon Detectors, EPA Evaluated
Sounded good, BUT...........
Not properly calibrated and Not approved for use in NJ by the State! Gives readings much higher than carbon absorption kits and therefore unreliable!! Wish I could return it for a refund!!!!!
- Important Device for Basement
It is easy to set up and to read. The instructions tell you how long you have to wait for an accurate reading, and I found the time was exact.
It is a little cheap, however, for its $100 plus price tag: The indicator panel that you need to stick on the front falls off....more info
- basically good fuctionality marginal
The unit gave a reading after 48 hours (as indicated in instructions) which was consistent with a mail-in test kit. The various modes that one is suppose to be able to select don't seem to work correctly on this unit but the basic feature of radon gas reading seems consistent and is very useful....more info
- Excellent product for short and long term testing
I purchased this device 2 1/2 months ago so that I could have an idea of what my long term readings are and how it changes week to week.
I was hesitant to purchase this product because I have read a number of reviews and comments about this device not being approved for sale in one or two states. However, I saw that this product was tested by a leading consumer magazine which gave this device a good rating. I believe that in order to get a good rating, the readings have to be within 20% of the actual level.
My belief is that my device gives readings somewhat higher than the actual level. Perhaps short term carbon testers give readings lower than the actual level. From what I read from the leading consumer magazine is that short term carbon tests from certain companies give poor readings, up to 40% off from the true level. The carbon tester I used was rated good, within 20%.
I used the carbon tester before the unit arrived to take some measurements. Based on the results, I feel my unit is giving me a reasonable reading (albeit somewhat higher). I also believe that my unit is very consistent in its readings so that the day to day changes are a true reflection of the change in radon levels.
This device measures average radon levels for the past week and also measures average radon levels since it was last reset. Since it provides an average reading over the last 7 days, any change I make to affect the radon level won't be completely accounted for until 7 days have gone by. However, if my readings are slowly dropping, then I think it is safe to assume that radon levels are lower than the current reading and vice versa.
I think the quality of the plastic covering the display could be substantially better. It is very thin, almost like cellophane. I would like to see a thicker piece of plastic. Nevertheless, the display is crisp and very bright (easy to read). It is always lit which I like. The unit comes with a UL listed power supply which is a big plus because I could not find anyone else that mentioned if the power supply was UL listed or not.
I would like to see a battery backup which it does not have. Unplugging it for a very brief period of time does not seem to reset it (a few seconds). However, I had two power surges (they were substantial) that made the device list an error code. Unplugging and re-plugging the device fixed the problem each time but this brought up another issue. The long term readings are probably only as good as the unit gets good power. I don't think I would be able to get a 6 month or 1 year average reading as I don't think my power is that reliable. If I want a 1 year average, I probably would have to purchase a long term test kit, but it would be frustrating to wait a whole year with no feedback. Even though I purchased this for long term testing, I still OK with it because I know what my long term reading is to date and can average it in to whatever it displays if I reset the unit.
Next year in February, I plan to purchase another charcoal kit and test the device. As long as the readings are less than 40% different, I will be happy; otherwise I will send the device back to be re-calibrated which is cheaper than buying a new one.
Despite the drawbacks, I give it 5 stars because it does what it was designed to do and I think it is the only game in town for an affordable electronic radon testing device. It measures down to 0.1 pCi/L.
I do suggest that if you buy this device that you also check it with a carbon device to make sure it is giving a reasonable reading. Please note that the short term carbon testers can be very inaccurate, so purchase one that has results that are within 20% of the real amounts. To find a good carbon testing kit, check with a leading consumer magazine....more info
- works great
The readings are real-time, albeit averaged over one week and thirty day time horizons.
The meter taught us that the radon is coming through our sump pump. We have a perimeter foundation drain that empties into our sump. When it's raining, our radon readings go up. When the ground is frozen the radon readings go way down. Now maybe we can manage the radon without buying a $1200 mitigation system....more info
- The best product of its style on the market
I got this product so I can tinker with my radon reductions system and observe the results. I am using sump hole suction, DIY. This is the only way to go if you want to check back and see if your system is working, without sending those test capsules to a lab. I don't really like the separate power supply, but it's no big deal; it still works well...more info
- Worth considering
If you're interested in a radon monitor, I'd give this one a close look. Radon detection does not seem to be an exact science, so I'm not sure any test is 100% reliable.
The Safety Siren Pro 3 is very sensitive to things like stereos and fluorescent lighting, and you don't want it near doors and heating registers, which really narrows down the spots to put it. If you ignore their guidelines in the manual, as I intentionally did at first to get it in the right spot, funny readings or error messages will result. Our first reading was 33 pCi/L. Then came error messages. Then I followed the instructions, found a good spot that met their specs, and since then it has worked fine.
How reliable is it? I have three sets of data from three different methods of radon testing in our house. I do not know which is most reliable, but here are the results. A professional radon test with a continuous monitor, closed house, was done in June. The basic levels were between 2 and 3, but with high levels and a peak of 27 during a thunderstorm. The average was 9. That taught us that averages can be misleading, and made us pay attention to radon in this house. The hourly readings from that professional monitor were much more useful, showing a house that was good in good weather and bad in stormy weather.
Following extensive work in a crawl space that had never had any work, not even a vapor barrier, we tested again, closed house. This time with the Safety Siren Pro. Readings were .3 or .4, very low. Since then we've lived in normal conditions, windows open, etc. Readings have been between .3 and 2.3 in our bedroom.
We did a direct comparison from Sept. 19 to Sept. 23, using a Pro-Lab test kit from the hardware store ($10 plus $30 for lab fee). The two canisters were analyzed as .3 and .1 for that period. The Siren Pro ranged between 1.9 and 2.3 during the same time. Which is correct? Don't know. And it's a big difference -- 1000%. On the other hand, both methods are suggesting low radon levels (for Indiana these are low). The Siren Pro shows an average of 1.0 for the last six weeks. (It has a button to push to see long-term average and short-term average levels.)
Since none of the three tests suggests that the house has high radon in good weather or since the crawl space work, it is not unlikely that the Siren Pro is approximately correct, good enough for our purposes. And since it appears to be the highest of the three tests, conditions taken into consideration, it may be giving us a margin of error in the direction of caution.
We would buy it again. Not saying we know for sure any of these tests are fullproof, but we have done nothing to mitigate radon other than the crawlspace work that had to be done anyway (perimeter drains, vapor barrier, sump pump, and running all downspouts from the roof far away from the house). So the Siren Pro has let us avoid the cost of radon mitigation, plus the annual cost of lost energy by running a continuous fan on a vent pipe in the crawl space.
It's very easy to use, and can be used forever, so in that sense it is easy to recommend it. The EPA sees it as a valid test. For $150 plus $40 plus $119, you can get a professional test, canister test, and the Safety Siren, and that may be $300 well spent if the professional test indicates high radon.
Assuming it's somewhat accurate, the Safety Siren lets you gather all kinds of valuable data while controlling different variables --ventilation in the basement, ventilation in the house, sealing gaps where radon might enter, etc. And you can also note variances in outside temperature and humidity and their effects....more info
- Warning: Can give misleading readings
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....more info
- Believe it really works
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....more info
- Quality Product
Product works as designed. Cannot compare to other devices since this appears to be the only unit of it's kind available to consumers.
-Real time monitoring of the radon level in my home. It allows me to track the fluctuations and verify that my radon mitigation system is working correctly.
-Beats the heck out of buying a kit and mailing in.
-Plugged the unit in before radon mitigation was done and reading was very high and close to the professional measure we had done for $175. After mitigation I watched the level on the unit fall, so even if it is not 100% accurate, it is doing what it was designed to do.
-Wish it was battery powered. Having a power cord limits placement when placement is already limited if you read the instructions.
-Only having one button makes changing settings cumbersome. Basically you control the unit and change settings by holding down the button for a specified number of seconds. Not ideal, but doesn't need to be done often so not a deal breaker.
Overall I am glad I purchased this. I was worried about the price tag, but having a visual readout of the radon level in my home gives me piece of mind, which is priceless to me....more info
- Useful, but not accurate
I have used the device in short-term mode for the last few weeks, and have found it to be useful for judging general radon levels, but not the accuracy achieved by professional testing equipment. It registered 6.4 in my basement after we insulated the house. I had a mitigation system installed and the next readings were 1.0 after 2 days wait for the system to work. I decided to have a professional come in and do testing - and over the course of the 3 days he left his equipment to run, I had the Siren placed right next to it with a memory reset. His equipment, post mitigation, averaged 0.2, and the siren showed 1.0. Not a huge discrepancy, but one that would have prompted me to explore more mitigation options using the Siren alone, as I wanted the level in my house to be that of average outdoor air - 0.4. The EPA standard of 4.0 is just plain not safe - in fact they say that you should get it as close to .4 as possible. I will continue to use the device in my basement for the longer term. However, read the fine print in the manual about calibration. Professional units need to be calibrated to read radon levels accurately almost on a yearly basis. This unit can be re-calibrated for a fee of $75, and you need to send it back to the company. So it may not be very useful after a year, although it is cheaper to re-calibrate than to purchase a new one. I have also seen online that you need to vacuum out the grills on the unit once a month, as the glass technology used tends to let particles accumulate.
My suggestion is to back up your readings with a professional if you want to see dead accurate results. My professional test over 3 days cost $115. And if you have granite counter tops in your kitchen, do yourself a favor and have them test for radioactivity (and therefore radon). All granite contains uranium, I have found, and it could contribute to radon levels. Luckily, the absolute black granite I have had negligible radioactivity above background levels - but the possibility of higher readings is out there, if very slim. Peace of mind is of paramount importance to me though....more info
- Solid Product
Purchased this to monitor radon in the house in preparation for installing a mitigation system. I can't comment on accuracy as there is no control to which to compare it but it does provide us with valuable information. I will likely purchase a second one to monitor both the basement and first floor in our house. ...more info
- Get it, don't screw with the $5-10 tests.
Why screw around with radon if you know you have a problem? You can use this sensor and move it around your basement/house letting it cycle for 2-5 days in each spot to narrow down the source. Find your problems and monitor them in real-time... Anyone who needed or needs a mitigation system should own one of these. Saving $$ now isn't worth it in the long run... If only the price of this unit could fix cancer... :( Might as well do all you can to avoid it!...more info
- Works as expected, but documentation could be better
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. Second, the US EPA requires mitigation at 4.0 -- but based on my research European agencies require mitigation at 7.0 and in some parts of Canada as high as 20.0 .
- If the reading is mildly high, say between 4 and 6 like it was in my case, then common sense maintenance tasks may take care of the problem. For example, covering up the sump hole with a piece of rubber tile helped bring the reading down to under 4.0 for us.
What radon mitigation people don't tell you is that you can cut your radiation exposure in half just by circulating the air in your basement. Moving the air around encourages the plate-out (settlement) of charged daughter particles of radon decay. It doesn't reduce the radon itself, but it encourages the actual dangerous stuff to stick to the walls and furniture instead of your lungs. The decay of the daughter particles is measured in minutes, and not even days. There is a guy who patented a ceiling fan as a means of mitigating radon. So, the point is -- mild increases in radon levels can be mitigated cheaply, if not for free.
To conclude, I find this device useful in general as a tool for measuring earth gases entering the basement. Besides radon there is a lot more harmful stuff that may be seeping in that you need to worry about. Ground water carries all sorts of disgusting stuff and in some areas of the country mildly high radon levels are the least of your worries (think arsenic, mercury, MTBE, etc.) So, if the Safety Siren is telling you you have mildly high radon readings it probably means you have mildly high levels of all sorts of other disgusting crap in your basement. Common sense methods of circulating the air, covering up the exposure to dirt, etc. is enough to control the problem.
UPDATE 3/4/09: I realized that I had the device's power supply right next to it. Moving it away from the unit lowered the radon reading by at least 1.0-2.0 pCi/L . It is now consistently below 4.0 . This is a finicky little gadget. I wouldn't rely on it as the source of all truth about radon. TRUST BUT VERIFY....more info
