Are you in the process of buying a new house? Remember to measure the radon levels before the final purchase.
To repair an existing house from high concentrations of radon can be a costly process, and thus it is a related expense for when you are negotiating the price of your new home. Therefore, sealed radon meters are the best solution, because with these you can be assured that the radon meters are not removed during the measurement period.
