How long should a radon test be conducted?
Because there are so many variables that affect radon, including weather, local soil and rock type, building type and construction materials, the longer the radon test is carried out the more accurate the result. The Nova Scotia Department of Environment and Labour recommends testing be carried out over a period of at least three months and, if possible, in the coolest months of the year. During the heating season ventilation is lowest and radon levels are usually at their highest. For accurate results, carefully follow the instructions included with your test unit.
