Efforts that have been made (installation of measuring - alarming stations, educational sessions for farmers, de-nitrification programs etc) during the same period are also referred.
An alternative policy for high radon areas that also required a radon measurement and installation of active measures such as an electric fan in homes where the measurement was above a certain level would, in principle, be more appropriate.
However, as the current policy does not require the measurement of radon nor installation of active measures, the effectiveness is similar to the policy for basic measures although the cost is higher.
A more logical policy for full preventive measures would require radon to be measured in such houses after construction and occupation, and the installation of active measures, such as an electric fan, when appropriate.
The watering down of the Energy Company Obligation (ECO) – regulations forcing companies to pay for the installation of green measures – is expected to lead to a saving of £30 to £35 on household gas and electricity bills where companies choose to pass on the savings.
