Of all the radon myths, one of the most popular is that short-term tests can’t help you make a decision about whether to fix radon in your home. The short-term tests can actually be more than enough information. With two radon tests, it’s enough to take action.
If you conduct two tests and at least one of these tests is above 4.0 pCi/L, then you should take action. Of course, monitoring your levels consistently will help you feel even safer against the threat of radon.
A short-term radon test is a great place to start. It will tell you if you should take action or if you do not need to do anything at all.
