Risk Assessment, Testing & Mitigation Services
What is Radon ?
Radon (Rn) is a radioactive, colourless, odorless, tasteless noble gas and special equipment is required to detect it.
Radon can be found everywhere in the UK, with higher levels in some parts of the country than others. The Government recommendations are that a property with a yearly average radon level of 200 Becquerel per cubic meter is at risk. The average concentration of radon in UK homes is only 20 Bacquerel per cubic meter.
Up to 2000 deaths a year in the UK are attributed to exposure to radon, which can cause lung cancer.
Which areas of the UK are at the greatest risk?
Public Health England has published a map showing where high levels are more likely. The darker the colour the greater the chance of a higher level. The chance is less than one home in a hundred in the white areas and greater than one in three in the darkest areas:
Do I need to carry out a risk assessment?
Radon hazards are simple and cheap to measure and relatively easy to address if levels are high. Under UK regulations all employers must review the potential radon hazard in their premises. Under the Health and Safety at Work etc Act 1974, employers must, so far as is reasonably practicable, ensure the health and safety of employees and others who have access to their work environment. The Management of Health and Safety at Work Regulations 1999 require the assessment of health and safety risks and this should include radon in the following circumstances:
Above Ground Workplaces: For the vast majority of above ground workplaces the risk assessment should include radon measurements in appropriate ground floor rooms where the building is located in a radon Affected Area.
Below Ground Workplaces: For occupied below ground workplaces (for example occupied greater than an average of an hour per week/ 52 hours per year), or those containing an open water source, the risk assessment should include radon measurements. This applies to all below ground workplaces in the UK, irrespective of the above ground Affected Areas status.
Testing & Mitigation
Initially, to test a property for Radon gas, you will need to place radon detectors within the building for a period of 90 days. These are small, unobtrusive devices which are extremely accurate. Once analysed, you will receive a certificate which details radon levels detected within your property.
If the results are considered to be above safe levels, MSS will provide a risk assessment and provide you with advice about the next course of action.
