Radon is a substance that cannot be seen or smelt, but is present in houses, whether new or lived in. There are adverse effects it is capable of. It is therefore important that certain tests be done to reveal how far the substance has spread, and how to get it neutralized. They come in handy when you are buying or selling a house, or you are in the process of building one.
For effective results, you need the test to be done at the lowest level of the house, such as the basement, play area, or workshop. You should also know about how long and when the test should be done. Tests should last more than two days. Nothing should interfere with the progress of the test.
There are special gadgets used in such a test. 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.
You will see some active and passive radon test kits. The passive ones do not need electricity to work. They should only be exposed to the air in the test area for a given period. They shall thereafter be taken to labs for analysis. These passive gadgets serve their purpose in both long and short-term testing. They are not that expensive. They are also great at minimizing the negative impact of interferences to the test.
Active testing kits cannot function without electricity. They come with continuous radon monitors and continuous working levels monitors in place. These measure and record the amount of radon or its decay products in the air as time goes. They are also effective at telling when there are radon level spikes. The report can then be interpreted by the inspectors. They are designed to point out and remove parts of the results that were spikes. They happen to be the better choice of kits.
The best way to reduce interference to the results is to use test devices that keep on recording the radon and decay levels, so as to note when spikes turn up. Motion detectors shall tell when there was some interference. It also tells if there have been changes in the test conditions. Proximity detectors can also tell if people walked into the testing room. Such are the factors that interfere with the results.
It is by also understanding the weather conditions during the test that you can tell how effective the results were. 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 points make up what needs to happen for an effective inspection to begin.
