Home inspectors are needed to conduct certain tests to determine what radon levels are present in the house, and what measures need to be taken to reduce those levels. 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. It is critical to determine how long and when the test should be done. There is no effectiveness in a test shorter than two days. The test also needs non-interference.

Active testing kits on the other hand need electricity to work. They have radon monitors that are always recording, both the levels and amount. They are there to monitor the radon amounts and their decay products constantly, as time passes. They are capable of detection of irregular spikes of the radon levels. The inspectors shall then explain what those spikes mean. They are capable of identifying and eliminating test interference effects. 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. They also also great at telling when there were changes in the test conditions. The proximity detectors are used to show when people walked into the test area. Such are the factors that interfere with 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. The windows and doors should have been kept sealed.
The party selling the house needs to agree to sign a non-interference agreement. Such are the primary requirements for a good inspection job on the premises.
