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. The testing takes a considerable period of which no other activity should be ongoing, and you need to schedule an appropriate time to do the test. The period of a short-term testing is approximately 48 hours, and there should be minimal or no interference at all.
Ensure that you hire a qualified home inspector to do the job because radon testing is a risky procedure. The home inspector you hire must be conversant with the different types of testing equipment available and how to operate them. If you do not mind, you can seek information from state offices that are concerned with radon testing, and they will explain to you the devices available and the best situation to use each one of them. You will realize that there are passive and active devices for testing radon. Passive devices are not powered by electricity, and they include charcoal canister, alpha-track detectors, charcoal liquid scintillation devices and electret ion chamber detectors. Each equipment is unique and has different requirements for efficient operation, but all of them need exposure to air for a specific period. After that exposure, they are taken to a laboratory for testing. Passive radon testing devices are widely used because they are affordable and they can be used for long-term and short-term testing.
Active devices for radon testing use electricity, and the most common ones are 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 instruments are more complicated than passive devices as they can display any unusual swing in radon levels. A competent inspector will study the variations and explain them in the report. If there is any interference during the testing period, then you will not get accurate results. 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.
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. Therefore, you need a tester or inspector who is conversant with all the issues that he can interpret the results correctly.
