Frequently Asked Questions for First Alert RD1 Radon Gas Test Kit: FAQs
Q1.How much area does the First Alert RD1 Radon Gas Kit cover?
Answer: The kit covers up to 2000 square feet. Remember, the kit will cover only those areas that are exposed to. If you are checking radon levels on 2 floors, you will need one kit for each floor. The United States Environmental Protection Agency recommends testing the lowest level of your home (the basement), since radon levels are highest on that side.
Q2.How long does it take to get the area tested?
Answer: This Kit is used for a short-term radon test, which can be run for a minimum of 48 hours (2 days) and a maximum of 96 hours (4 days).
Q3.What is the shelf life of the Testing Kit?
Answer: It can probably last forever if kept sealed, as the literature on the packed product says.
I believe the literature packed with the product says “indefinite” — like forever — as long as it remains sealed. For detailed testing, leave the packet open but not in a sopping or drafty area for about 48 hours.s
Q4.What are the other/extra fees to obtain results?
Answer: It’s 10$ for anywhere in New York.
Q5.How do you test using the DIY kit?
Answer: It’s an activated charcoal test, meaning you place the included packet in the room you want to test, and the charcoal will absorb radon gas if present. When you ship it to the testing lab, they can see how much radon the charcoal has absorbed.
Q6.Which areas are recommended to be tested?
Answer: The radon levels are maximum in closed areas. It is recommended to start with the basement, as radon is a major source underground. If the window below your apartment is left open, you will not get an exact reading.
Q7.Does this test tell you the extent of radon or simply positive/negative?
Answer: The test results give you the level of radon found in the space, like a numeric value, so you can take the necessary measures.
Q8.How do you start the test? Should you puncture the top-sealed paper or peel it off?
Answer: You keep the container sealed. Do not have to slit or remove the seal.
Q9.Where can you find the test results after you submit them to the lab?
Answer: You’ll be able to download the results of your test online at DrHomeAir.com/Results. Your report will be sent to you when it’s complete via the channel you indicated on your test form (email, fax, or US Mail). However, sometimes the report doesn’t reach you at all for some reason. In addition to the website, you can always call 800-324-5928, and we’ll be happy to send another copy of your report to you at any time.
Q10.What is the best time to test?
Answer: Since radon levels can vary consistently with the weather and therefore the season, it’s important that you simply test your home for radon when all windows and doors are often kept closed, apart from normal entry and exit, before and for the duration of the test. In northern climates, winter is the optimal time to check. In southern climates, the test should be performed when windows and doors won’t be opened for ventilation. Also, it’s acceptable to continue operating central air-conditioning systems that recycle interior air during the trial period. It’s also important that you conduct the test when the weather is calm. Testing during high winds (30+ mph) or thunderstorms can seriously alter radon levels. If you start testing when the weather is calm and severe weather arises during the test, BRK Brands, Inc., the maker of First Alert® brand products, recommends completing the test but conducting another test as soon as possible during calm weather. If the test results indicate different radon levels, the extent of the test conducted during severe weather should be discarded.
