ATDGI renews its certification by the Portuguese Environment Agency (APA), as an entity providing services in the measurement of radon by passive detectors in the internal air of buildings.

What is Radon Gas?

Radon is a radioactive gas of natural origin that comes from the decay of uranium present in the rocks and soil from which it is released and rises to the surface.

  • Radon is present everywhere, outside and inside buildings.
  • In outdoor air radon concentrations are low due to dilution and dispersion, but inside buildings radon can accumulate and concentrations be high.
  • Radon enters buildings from the ground, through cracks or crevices in the floor and walls, through joints between the floor and wall, and through poorly or uninsulated plumbing.

Is it mandatory to measure Radon gas in facilities?

Given that prolonged exposure to radon has harmful effects on health, legal instruments are in place to protect both the public and workers. There are specificities, depending on the location or type of building, but in general, the obligations under the responsibility of the employer are:

  • Radon analysis at least once in every workplace.
  • After the first measurement, carry out periodic monitoring of this gas according to the susceptibility zone of the location.
