Key Consideration When Testing For Radon in Premises
Radon is a health threat and it might be impossible to see or smell but it can be present in the home you are purchasing, selling or constructing. For that matter, you need to hire the services of home inspectors or other relevant professionals to test for radon presence and recommend ways of reducing its levels. The reliability of the radon testing results is crucial. To get the best outcome, the test must be carried out in the lower sections of the home which has regular activities such as the basement, play area, workshop or garage. Testing takes some period, but it must be adequate, and you must organize an appropriate time for carrying out the tests. The period of a short-term testing is approximately 48 hours, and there should be minimal or no interference at all.
There are special devices for testing radon presence in homes. This is specialized testing equipment that most home inspectors are conversant with their use when testing radon in premises. You can get information on the latest radon testing equipment from state offices that deal with radon issues, and they will also inform you about the best testing methods that are applicable in different circumstances. Two radon testing devices are available currently, and they are; passive devices and active devices. Passive radon testing instruments do not need electricity to perform testing, and the widely used types are alpha-track detectors, charcoal canister, electret ion chamber detectors and charcoal scintillation devices. Every instrument is operated differently, but all of them must be in openly to air in a house for a definite period. After the duration of exposure to air elapses, it is taken for laboratory analysis. Passive radon testing devices are widely used because they are affordable and they can be used for long-term and short-term testing.
Alternatively, you can opt for active radon testing devices which need electricity to function and the two regularly used devices are; continuous working level monitors and continuous radon monitors. These tools are useful for measuring and recording the presence of radon and their levels in the area in a fixed period. The active devices have more advanced features than the passive gadgets because they have a display unit which shows the fluctuation of radon levels in the apartment. A competent inspector will study the variations and explain them in the report. If there is any interference in the process of testing, this will likely affect the results. Therefore, some of the active devices have anti-interference features which help to guarantee a reliable outcome.
The environment in which the testing is carried out must be conducive such that it does not have any influences of weather factors such as temperatures and pressure. Motions by objects and people can also impact the outcome of the testing. You need a knowledgeable inspector who understands every aspect of testing in detail.
