Radon is a colourless and odourless radioactive gas of natural origin. It is a major indoor pollutant and is carcinogenic, being the second greatest cause of lung cancer after cigarette smoking. It can be transported by other gases and water into building interiors.

The TV channel RSI1 devoted the episode of October 10, 2010, of its programme “Il Giardino di Alberto”, to the Radon issue.

ECONS SA is a metrology service recognized at federal level, so it is certified to carry out official radon measurements, which are then registered in the Federal Radon Databank. This procedure is mandatory during the sale of real estate. We are also included in the list of radon consultants (full list).

For more information

Radon (Rn) is a gas that derives from the decay of radium (naturally occurring in the soil), which is itself the product of the decay of uranium. From the soil where it originated, radon can infiltrate buildings through cracks in the walls or floors, and via electrical utility and drinking water ducts. Once inside, it can spread to all floors and rooms of the building.

The regulation of the radon problem is governed primarily by the Radiological Protection Act (RPA) of 22 March 1991, and the Radiological Protection Ordinance (RPO) of 22 June 1994, which emphasize the importance of preventing ionizing radiation risks, radon concentration limits in work and residential buildings, and measurement methods.
