You always begin by performing an accredited long-term measurement over a minimum period of 2 months. If the result is high you should go to Step 2.
At high radon levels, a radon consultant with documented radon expertise should perform an inspection to determine the source of the radon and then suggest measures to reduce radon levels.
With an inspection protocol, it is sufficient data to submit a tender to 2- 3 mitigation professionals in your region. Verify that they are certified professionals with experience of radon mitigation.
When a mitigation professional is selected, the mitigation can be performed to reduce radon levels in the home.
Within one year of the measures being implemented, a follow-up long-term measurement must be performed to verify that the measures have worked. This can be done with radon detectors.
In order to ensure that radon mitigation and implemented measures are having the intended effect, homeowners should continue to monitor radon levels. This can be done using a digital radon monitor that enables variations in radon levels to be monitored over time.
You now live in a radon-free environment, and the radon grant will be paid out if you have followed the specified actions. Home radon levels should be monitored by means of long-term measurement every five years, or in the event of any major renovation work. This helps to ensure that the measures are still working.
