Radon is a naturally occurring radioactive gas produced by certain types of rocks and soils across large areas of the UK.
It has no taste, smell or colour and special devices are needed to measure it.
Radon can be inhaled and absorbed and people who are exposed to high levels of radon are more likely to get lung cancer.
Although most of Newport is classed as a ‘potentially radon affected area’ the majority of properties are unlikely to be affected by high and potentially harmful levels of radon gas.
Employers are required by the Management of Health and Safety Regulations at Work 1999 to assess risks from radon in workplaces in radon affected areas.
