Radon Gas
Radon gas is a naturally occurring radioactive
gas that is released from some types of geology such as granites,
limestones and some shales. Although the gas is radioactive, it is
not considered to be a health issue until the gas becomes trapped
in a confined space and concentrations of the gas build up to
levels that are considered to be of concern.
Previously the likelihood of the presence of
radon gas in an area has been modelled on either actual radon
measurements within a property or the types of geology present.
More recently however the British Geological Survey in
conjunction with the Health Protection Agency have combined
these two modelling methods and as a result new radon affected
areas within the Borough of Cheshire East have been identified.
The identification of new radon affected areas has two
implications for the residents the live in affected properties:
- Health studies around the world have linked radon with lung
cancer. Radon is the second largest cause of lung cancer. People
who are exposed to high levels of radon are more likely to get lung
cancer, and the risk to smokers will be much higher than the risk
to non-smoker.
- A local authority search, which is undertaken when a property
is sold, identifies if a property is located in a radon affected
area. As radon levels vary from property to property, getting your
house tested for the presence of radon gas before putting a
property on the market can avoid delaying the sale whilst the test
is undertaken, or potential lengthy negotiations on the purchase
price.
The test for radon is very easy to undertake
and consists of two discs, which should be placed in a living room
and an occupied bedroom. The detectors are a piece of spectacle
lens plastic in a protective shell and around the size of a small
doorknob, the lens measures the amount of radon present over a
period of three months and is analysed by experts at accredited
laboratories.
To find out if your property stands in a radon
affected area follow this link to the UKRadon website.
Tests and further information with regard to radon are available
directly from the Health Protection Agency (HPA)
website.
