Radon Monitoring

If you currently live in a Radon Risk Area in the UK or are considering buying property in such areas, you may be wise to check for the presence of Radon Gas.

By placing detectors in you home / workspace, and leaving them in place for a set time (minimum 30 days), the detectors can then be sent off for analysis, and and risk to the inhabitants / employees can be measured.

A report can then be produced to satisfy a HIP (Home Information Pack) or similar.

For more information on the causes of, and the problems caused by Radon Gas please read the DEFRA Guide

If radon is found to be present, then there will be design implication for a new build project, or modification required for existing structures, these details can be discussed with your architect.

For the home owner, you may wish to arrange your own testing, which we can advise on, at no charge. However, for larger concerns, organisation and implantation can be outsourced to Southwest Environmental.

Radon gas linked to cancer deaths

Domestic exposure to radon gas is responsible for a significant number of lung cancer deaths, research has found. The risk appears to be much higher for smokers. The researchers conclude radon in the home causes approximately 20,000 lung cancer deaths in the European Union each year - about 1,000 in the UK.

Agency Underwhelms on Radon

The Health Protection Agency has decided against cutting its radon “action level” in the wake of last year’s advice from the World Health Organisation.
 

Where will SWEL carry out Radon Monitoring?

We will carry out Radon Monitoring in any part of the UK, we have offices in London, Bristol and Exeter.

How Long does Radon Monitoring Take?

Radon Monitoring is carried out over a minimum period of 30 days, this may seem inconvenient particularly if the radon monitoring is being carried out as part of a property acquisition but is essential that radon monitoring is carried out over a minimum of 30 days in order to obtain an accurate gauge of radon concentrations within the property. If a short time period is used, the labs will not accept the detectors, a 90 day monitoring period is typically the recommended period.

How does Radon Monitoring Work?

Put simply. Each radon detector contains a film which is "marked" when an electronically charged decay product passes through it. They films are then analysed to check for the presence of these "marks" or etches. The number of marks or etches will have a relationship with the concentration of Radon Gas found in the monitored air space and thusly a concentration is derived.


Radon Report Contents

A radon report produced by SWEL will contain secondary and primary data to describe the risk on site. We arrange installation and testing, and interpretation of results along with design recommendation and cost estimates where the scope allows.

Use of Accumulators

In the past SWEL have explored the notion of using accumulator cells for the collection of ground borne gases including radon. This method would allow monitoring for radon ahead od construction which one would assume to be advantageous. In the USA this method is sometime used to assess radon levels. However it is very limited and in the UK may result in complications. Rather than having prescribed "safe" levels in the UK, we have "action levels", these cannot be manipulated to account for the use of accumulators and as such results from accumulators would have to be presented in direct comparison with these action levels. Results from accumulators are likely show higher concentration owing to a low ground area to sample air volume ratio, and thus results from accumulators would likely have a negative bearing on onward mitigation costs.
