What is Radon?

Radon is an odourless, invisible gas which is produced due to the radioactive decay of uranium in the ground. It can therefore be classified as radioactive. The latest information about its effects indicates that radon represents a high, environmentally-related radiation problem in enclosed rooms – strangely its effects are often underestimated and ignored by the general public. Radon can accumulate in our organs and cause cancer. Planners, installers and developers should, in cases of doubt, seek the binding advice of specialists and obtain the necessary measurements. It is possible to solve the problem of radon through structural measures and thus protect your health. If you require further information please contact us.
