First Alert Radon Gas Test Kit, RD1

Good price and I have already used the test. Easy to use and should provide fast results.

Chances are if you are reading reviews for a carbon-based Radon test kit, you already have a general idea of how they work and what they test for. This test kit comes in a small box, it contains a sealed tray of a charcoal-like substance that you sit in the spot where you want to run the test for 48-72 hours. After that time, you put the kit back into the included envelope along with a completed information card, seal it up, and mail it away for testing to a lab. Simple enough.To sum it all up, I was very satisfied with this product from start to finish. Here is my review, focusing on a few key areas that I feel need to be addressed based on reading the product information and other customer reviews:Ease of Use:I found this kit to be as simple to use as it could possibly have been. The only contents of the box are exactly what is necessary. The instructions are short, but thorough enough that they provide you with everything needed to maximize your chances of a successful and accurate test. It goes over the basics of how to use the kit, recommended places to place it, conditions your house needs to be in, etc. Once you've run it for 48-72 hours, you just record the necessary information on the info card, drop it in the envelope, and off it goes to the lab.Hidden/Additional Fees:The price of this kit includes the lab analysis and results reporting, so there are no "hidden" fees. However, the kit gives you the option to pay an additional $10 for "rush processing". I did not opt for this, so I can't comment on how much faster the results would have been, but I assume this would be useful for things like real estate transactions. This test was only for my own information in a house I already own, so speed of results wasn't a top priority for me. The only other potential "hidden" fee is the cost of postage to return the kit. The return envelope states that you must attached 5 first-class postage stamps. So that's a little over $2 of postage required to send the kit in for testing. Not going to break the bank, but I felt it was worth mentioning.Speed of Receiving Results:This is the main area I wanted to focus my review on. There are many other reviews that are complaining about how they sent away their kit and never heard back again, or had a very difficult time interfacing with the lab to get their final results. Like I mentioned above, I sent my kit back without opting for the rush processing service. My test finished on Sunday, January 13th. It was sealed in an envelope and dropped in the mail on the morning of Monday, January 14th. Standard first-class mail. I received my results back in the form of an email with a PDF attachment today, Monday January 21st. Seven days total for results, including the time it spent going from Maryland to Texas in the mail! I couldn't believe it when I received the email. Many others complained of it taking 2-4 weeks to get results, or never hearing back at all. I can only speak for my one experience, but I was extremely satisfied with the speed.Accuracy of Results:I chose to use this carbon-based test kit as a supplement to another kit I had purchased, the Safety Siren Pro Series HS71512 3 Radon Gas Detector. The Safety Siren Pro kit is significantly more expensive, but gives a short term (2 day average) reading as well as a long term (7 day average) reading. I placed both a few feet apart when I ran the test. My Safety Siren digital reader showed a result of .8 pci average over a 7 day test, and the results I received back from this First Alert test kit had a reading of .7 pci. This is extremely close, and made me feel confident that both kits are likely to be accurate.All in all, I rate this product a full five stars based on my experience, and I would have no issue recommending this kit to anyone else looking for a short term radon reading. Follow the simple directions, and you'll be satisfied.

I purchased the gas test kit for pace of mind after learning about the risks of radon in older homes. The instructions were clear and easy to follow- just set the kit in the designated room, leave it undisturbed for the recommended time, and then mail it to the lab using the prepaid envelope.

We used this radon testing kit twice. The first time we used it was in March. The instructions were easy to understand and the product could be registered online. When the testing time concluded, it was mailed to the company. We received results in just a few weeks. We ran another test a few weeks later to confirm that the results were accurate. The radon readings were both high, but around the same number. We have since installed a radon mitigation system

Why did you pick this product vs others?:First alert brand. Very easy to use and online registration is easy as well. Quick results. Yes. You have to pay shipping back , but still a cheap way to test for radon. Highly recommend.

The Minimum Detectable Concentration (MDC) for this kit was 3.3 Ci/L. Per their email (and other sources):The U.S. indoor average is 1.3 pCi/L, and the outdoor average is 0.4 pCi/L. If your result is greater than 4.0 pCi/L, the Environmental Protection Agency (EPA) recommends you take action to reduce the radon level. This may include re-testing. The Environmental Protection Agency (EPA) and the Surgeon General recommend that you consider taking action if the level is above 2.0 pCi/L. The World Health Organization (WHO) recommends mitigating your home if the radon level is 2.7 pCi/L or above.In other words, they're selling a test kit where the limit of detection is HIGHER than the action limit. Complete waste of time and money. Avoid!

This test appears to be cost effective because they tell you that the lab processing cost is included.What they do not tell you is that you have to pay for shipping it to the lab, which ranges from $12.50 to $35, depending on shipping speed. They also tell you after you register that for best results you should pay for expedited testing and shipping, which would mean your $16 test would end up costing you an additional $60 in processing/shipping fees.To add insult to injury I did not receive a shipping label by email after paying the $12.50 shipping cost. Edit: They did eventually email me a shipping label later in the day.Do not buy this product. It is a scam and so far just a waste of almost $30.

The instructions are straightforward. I put the 2 test kits near each other, as directed. The results were 1.6 and 1.8 picocuries per Liter, which are typical of my geographic area. The agreement of those results, if reliable, show that the kits will give reliable results, as well. I used UPS for return of the test kits after sampling.Many will probably not understand the decay chain of Radon but two things jump out at me. The test kit samples radon as a gas, but when radon decays it decays to a non-gas form. So, it may be more difficult for a person to breathe out the decay product. Then, The decay chain emits 4 alpha particles, which by way of comparison, you might say, is having somebody shoot you with one bullet but you get hit 4 times. I think the Wikipedia article says that Radon is a very dangerous substance - with good reason.
