When conducting radon tests, choose the lowest level of the home that your household uses at least 8 to 10 hours per week. For most people, this may be the ground floor. For others, it may be a regularly used basement.
These tests measure radon levels for a couple of days up to a week. Based on the results, homeowners know whether or not further testing is required.
Because radon levels can fluctuate over a period of time, long-term measuring provides a more accurate reading than short-term alternatives. Long-term tests measure radon levels for up to one year.
Use electric monitors to provide an average of detectable radon every day. These plug into a regular electrical outlet and can be used for both long-term and short-term testing.
