January is National Radon Action Month. A year ago we asked how you protect your home against radon. Share what you found out when you checked your home, and what you did about it.

    I have had my crawl space sealed. There is no connection between what’s under the house and the house. I did this to eliminate odors but the process precludes Radon entry to the house.

    you can buy a radon detector for under 100.00 and sample your home very easily. before you do, you can actually check the probabaility of being located in an active radon area via USGS site.

    We had a short-term test done by a professional when we bought our house nearly 3 years ago. The test revealed a level of 4 pCi/L. We ordered a long term test through the EPA website/National Safety Council earlier last year. The results were slightly above the action level.

    I located a certified radon mitigation contractor through my state’s public health and environment website, and we are scheduled to have the mitigation performed tomorrow. Total cost is less than a thousand dollars.

    We obtained a free radon test kit from the state and found the concentration to be more three times EPA’s recommended maximum of 4 pCi/L. We bought a second test kit and got the same results.

    We then contracted with a certified radon mitigation contractor and installed a sub-slab depressurization system. With two penetrations through the basement floor, abandonment and capping of a basement french drain, and sealing all the cracks and air leaks through the concrete floor, we are now comfortably below 4 pCi/L.

    I got a radon test kit from the Cooperative Extension Service. The cost was under $7 and they offered an educational presentation on radon. It was very helpful.

    We do not live in a radon region.

    The only way to know if your home has radon is to test; testing is inexpensive and simple. I applaud those who have done this already and encourage others to do the same. There is no such thing as a “radon free” region; high levels of radon have been found in homes in all states and countries.

    I tested my home with a very short term device (2 weeks). I obtained it from the Colorado Springs Health Dept. The measured results were below the EPA 4 pCi/L. This was just a quick measurement to see if I had any significant issues. If I was in a position at EPA I woudl issue free long term devices with instructions and have the data available by web.

    I went to visit my family this past weekend and brought my mom and each of my brothers radon test kits for their homes. I bought the kits for $10 each at the local hardware store. I set up the kit in the basement of each house… it was so easy!

    Now all they have to do is leave it out for 4 days, cap the 2 vials, then mail them in! They’ll have the results in only a few weeks.

    Radon testing is a smart preventive measure we can all take to lessen our risk of lung cancer. I’ve just learned about radon after watching your infomercial. I will definitely request for the test kit.

    A thousand dollars to install a radon device is a bit steep for me, but if I weigh the benifits, I would say it’s worth it. Another less expensive way we can keep radon out our home is to keep some airflow going in our home. We would want to do that anyway for other healthy reasons as well.

    My friend told me that her neighbor had granite kitchen counters. When she got her radon testing for her home, her counter top showed high radon concentration. I was wondering if this is true about granite. If granite emits radon, are there different levels of pci/l concentration for different kinds of granite? Can someone please comment on this.

    For information about radon and granite countertops, go to and look up FAQ #5103.

    How did you get your free radon test kit from the state? I need to test my home and I need this information. Thank you.
