If workplace radon testing has revealed radon concentrations above the compliance level of 300 Bq/m3, you may need to appoint a Radiation Protection Adviser (RPA).
The Ionising Radiations Regulations 2017 (IRR17) apply to any workplace with annual average radon levels in excess of 300 Bq/m3. The Health & Safety Executive advises that “A Radiation Protection Adviser (RPA) with radon experience should normally be consulted about how best to manage radon exposures”.
An RPA will assess the level of radon present and the normal occupation pattern for employees. This will allow them to calculate the individual radiation dose that employees receive and compare this to limits set out in IRR17.
In the short term, an RPA can advise on maximum permissible daily or weekly time limits for employees to occupy the area of the workplace with high radon levels, along with reporting and monitoring requirements.
In the long term, it is usually more cost effective to install radon mitigation systems to reduce the levels of radon within the building. This allows the employer to make full use of their premises without restrictions on occupation times or the administrative burden of keeping precise usage logs.
HSE advises that “if the employer plans to introduce engineering controls to reduce the radon exposures, they will also need to consult a specialist radon removal (remediation) contractor.”
It is vital that after any mitigation work is completed repeat radon testing is carried out to confirm that levels have fallen below 300 Bq/m3 so that the conditions of IRR17 can be lifted.
PropertECO work with a number of RPAs nationally to assist clients with meeting their legal obligations and offer a full radon consultancy, testing, design & mitigation service.
