Halton schools to be tested for radioactive radon gas

RADIOACTIVE radon gas could be present in more than half of the borough’s schools, according to Government health chiefs.

The Health Protection Agency has contacted Halton Council as part of a national monitoring campaign, warning there is a ‘small risk’ of the presence of radon in up to 36 of the borough’s 69 schools.

Monitoring equipment will now be fitted in the suspect buildings in three stages over the next six months to determine whether or not they are contaminated.

Radon is a naturally occurring radioactive gas and is present in the Earth’s crust.

It is odourless and colourless, can build up over time, and high levels have been known to increase the risk of lung cancer.

Hugh Lamont, of the Health Protection Agency, said: “This is routine and there’s no cause for alarm. Halton may have slightly higher levels of radon than normal, but it is still comparatively low.

“If we do find raised levels, remedial action will be taken.”

A Halton Council spokeswoman, added: “As part of an initiative led by the Health Protection Agency, and in common with other local authorities across the country, the council is conducting a radon survey in schools.

“Radon levels are measured on a scale from Class 1 (lowest) to Class 6.

“Some parts of Halton have been classified at a very low level (Class 2) which is why we are required to undertake surveys in the schools as a precautionary measure.

“Monitors to assess the levels of radon are being installed in the relevant Halton schools for three months. They are being installed in three phases, November 2009, February and May 2010.

“All headteachers have been briefed and all those schools affected have been issued with letters and a set of frequently asked questions.

“At present there is no need for any other actions and the schools can continue as normal.”

Dr Peter Cole, radiation protection advisor, added: “Radon is heavier than air and so tends to collect in the basements of buildings, especially where there are no windows for ventilation.

“Radon only becomes a significant problem for people if there is prolonged occupation of areas where the gas is present in high quantities. This is rare, however, and normally radon can be reduced by good ventilation.”
