Radon is a substance that cannot be seen or smelt, but is present in houses, whether new or lived in. It is a danger to your health. You need a home inspection to come in and do certain tests, to tell how much of it is present, and how to get rid of it. The expertise of these inspectors is thus needed at such buying and selling times.
For effective testing they need to focus their work in places like the basement, or any other low area. It is critical to determine how long and when the test should be done. The shortest length should be two days. There should be no interference to the testing process.
There are specialized equipment for such work. Home inspectors have said equipment, as they are qualified to use them. It is important to know about these equipment, to determine which inspector is best up to the job.
There are passive and active radon testing kits. Passive ones do not need electricity to work. They only need to be exposed to the air in the house for a given period, as per their settings. They will then go to the lab for analysis. These passive gadgets serve their purpose in both long and short-term testing. They are quite affordable. They can also keep interference agents away from the final results.
Active testing kits need electricity to work. They have continuous radon monitors and continuous working level monitors. They are there to monitor the radon amounts and their decay products constantly, as time passes. They can also detect and report unusual spikes in radon levels as the test progresses. The report can then be interpreted by the inspectors. They are capable of identifying and eliminating test interference effects. They are thus the more reliable kits for such tests.
The best way to tell how much of the result were interferences or related to interference situations, the inspectors need to use gadgets that shall keep on recording all the levels realized. Motion detectors shall tell when there was some interference. They will also point out changes in the test conditions. The proximity detectors are used to show when people walked into the test area. Such intrusions can affect the results.
When you can tell more about the weather conditions, you will know how effective the test results shall be. Temperature readings will also tell if there was an intrusion into the test area. It is best if the windows and doors remain sealed.
The party selling the house needs to agree to sign a non-interference agreement. These are the things you need a home inspector and radon tester to make sure are in place before they begin doing their job.
