Key Consideration When Testing For Radon in Premises
Many people are not aware of the health threat that they are exposed to in the homes with the presence of radon which is harmful. Unless a professional home inspector performs certain tests, you will not know that it is present because you cannot see or smell radon. In this entire process of testing for radon, you need reliable results. A tip to ensure that you get credible results is that you perform the test at the lowest level of the house which has lots of activities like play area, old storeroom or garage. Importantly you must decide the duration of the test and the best time to do it. 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. You will realize that there are passive and active devices for testing radon. 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. Each equipment is unique and has different requirements for efficient operation, but all of them need exposure to air for a specific period. After the duration of exposure to air elapses, it is taken for laboratory analysis. Most people prefer using passive devices because they can be used for short and long-term testing and they are also less expensive.
On the other hand, active testing devices are powered by electricity, and they include the use of continuous radon monitors and continuous working level monitors. They are suitable for measuring and recording radon levels in a particular room over a specified time. 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. Interference is the primary challenge in testing radon, but some active devices are designed with features to minimize interference. The introduction of anti-interference devices come as a relief to many people because you are guaranteed of getting a reliable result, but the only disadvantage with them is that they are expensive.
There are other factors which affect radon testing, and they might include weather conditions such as temperature and barometric pressure. Any movements with the premises might also affect the results. Therefore, you need a tester or inspector who is conversant with all the issues that he can interpret the results correctly.
