Accurately Monitor Radon Levels in Your Home with the SafetySiren Pro4 Series Radon Detector

Mick: The picture shows its a colored LED and the unit I received is not a colored LED but black lettering. Heard to read especially in the dark.

DFN: I bought this to replace my older Safety Siren 3 radon detector. I’ve been using the Safety Siren. 3 for several years. It always stayed within the acceptable range, but that model requires a periodic factory recalibration, so I bought the newer Safety Siren 4 that doesn’t require periodic recalibration. I was please to find that my older model 3 was within a few tenths decimal points of the newer model. I have never sent it in for recalibration and it’s still working too.

I would buy the Safety Siren 4 again!!!

walking jean: Without purchasing several different brands of radon detectors, or bringing in a professional, we have no idea just how accuate of a reading this device offers, but we trust it, and are assuming it is a good device.

Megan J.: After reading about it being the leader in home radon detection since 1993, I felt pretty good buying this one. Also reading the comments, that were super helpful with reviews on its accuracy etc, also helped me to buy this unit over others. We recently added a home theater to our finished basement just before Thanksgiving and have since been spending about half of our time down there. My mother had told me about radon gas when I was growing up and she had encountered it and questions about it as a realtor. I remembered this and wanted to be sure it was safe in our basement with us being down there so much now days. We followed instructions in the booklet provided and got results as it stated. Happy we are within safe measurements and can rest easy spending so much time down there ourselves, as well as having family and friends over as well. The peace of mind is worth the money for something like this, as a lot of people don't even know about radon gas, let alone the dangers/risks of it. I'd highly recommend this unit to anyone and have in my personal life!

Bill Dawson: Easy set up. Don't know how accurate it is but its seems ok.

michael: How can you measure the accuracy on the product? It seems ok. You would need a device to measure accuracy. I don't have one. Am I satisfied with blind trust, well yeah.
I had an older model and got years of use out of it. Like this one no installation, just plug it into the wall.
The only thing I am not fond of in the c connector that plugs into the device from the wall socket. The old unit had a round plug in to the device which seemed a little more sturdy.
Overall have got good results from the device and reading are similar to the old unit I had.

Rick753: I haven’t even had the unit for a week yet but after 2-4 days I got my first readings which were 1.4.

Rob: The radon detector was received in the time expected and in a bubble envelope. It is winter and the unit was allowed to warm to room temperature. Next, it was plugged into the wall outlet. An error message appeared upon initialization. Per instructions, electric power to the unit was cycled. This time the unit came up with the correct response - beeps, flashing CAL, then dashed lines for short term and long term readings in pCi/L. Per instructions, readings appeared in place of the dashed lines in 48 hours. I had placed the device in a bedroom of the house on the second floor. The initial readings were 1.8 pCi/L. This is close to one-half of the EPA action limit of 4.0 pCi/L or 148 Bq/m^3. (Each 1 pCi/L is equal to 37 Bq/m^3.) The WHO states that 2.7 pCi/L or 100 Bq/m^3 is the action level. The WHO also states that lung cancer risk will increase by 16% for every 100 Bq/m^3 of long term exposure. It is also important to remember that cancer risk is based on long-term exposure. It does not matter if the exposure was continuous or intermittent. Exposure to radon adds up over time. If you have moved from one house to another, each new exposure adds to long-term exposure. After 7 days...
