There have been a variety of studies that have demonstrated that radon is dangerous to the health when it is present at levels over what has been determined to be reasonably safe. That makes a radon gas test an important part of keeping the home environment as safe and healthy as possible, as there are ways to reduce the amount of radon present, once you know that there is a problem.
With testing so important, it is a good ideal to familiarize yourself with the available radon gas test methods, so that you can choose the means of testing most suitable for your needs. Radon gas test methods fall generally into two categories, passive and active.
The passive radon gas test methods can be done in a building without power, before you move into it. These tests use such substances as charcoal and are left in an area to absorb the air and, if present, the radon. After a set amount of time, the radon gas test is then submitted to a lab for analysis.
An active radon gas test runs continuously and requires a power source, as it is actively and constantly testing and keeping track of the levels of radon present. This constant measuring is thought to be much more reliable than the passive sorts of testing. This sort of test may be suitable for a site that has had a consistent problem with significantly higher than permissible levels of radon in the air.
A radon gas test is an important part of ensuring that your home environment is as healthy and safe as it can be. The best type of radon gas test for your home will depend on the specifics of your particular situation. In a home that has never shown a high radon level, a passive test may be fine. For a home that has experienced a significant problem, the active radon gas test may be the better choice.
