Luckily, in my opinion, this is a pretty cut & dry task.  The home inspector often does the radon inspection, as the results either come back acceptable (based on the Federal Environmental Protection Agency (EPA) value of less than 4.0 pCi/L) or the value is elevated which means the basement needs radon mitigation. (See previous blog entry: Opt in or out of a radon test?).  Fortunately, the test is scientific and is not under the interpretation of the home inspector or an individual radon inspector. 
 
Did you know that Greater Cleveland, Ohio and all of Northeast Ohio is a hotbed for radon and that radon is the second leading cause of lung cancer in North America behind smoking?  I strenuously recommend to all my buyers to obtain this potentially life-saving test.  The overwhelming majority of sellers are willing to install a mitigation system at their own expense ($800-$1,200 on average) in order to keep the purchase agreement intact.
