AXR - centrifugal in-line fans for radon gas migration ≤450 m³/h

  • AXR - centrifugal ducted fans for the direct extraction of radon gas from domestic, commercial or public premises
  • Problem description. Radon gas enters the human body by breathing contaminated air containing radon decay products. Radon decay products are radioactive and can cause lung cancer. Radon gas is one of the most common causes of lung cancer, leading to hundreds of deaths each year. The Council of the European Union has issued a Directive that sets basic safety standards. It also addresses the permissible levels of radon in rooms where people regularly spend several hours a day. The new annual average concentration of radon gas is set at 300 becquerels (Bq) per cubic metre per year. Radon gas is a radioactive gas that cannot be seen, smelled or felt, but can only be detected by measuring instruments. The Radiation Protection Centre continuously tests for naturally occurring radon gas in indoor air, soil and water, and updates the interactive radon map of Lithuania by summarising the results of the tests. The highest human exposure is not from X-ray diagnostic tests or nuclear power plants, but from naturally occurring radioactive sources. One such source is naturally occurring radon gas. Indoor concentrations of radioactive radon gas vary depending on the season, the type of ventilation in the house and the lifestyle of the occupants. The highest levels of radon accumulate on the ground floor and in underground rooms, which is why multi-storey buildings have a lower radon risk. Radon exposures can be reduced by proper design of new buildings or by radon mitigation measures in existing buildings. In particular, it should be assessed whether the site on which the building is to be constructed is located in an area where higher concentrations of radon activity have been identified in indoor air. This can be done by consulting the interactive radon map of Lithuania available on the website of the Radiation Protection Centre. It is recommended to install fans in existing buildings to remove potential indoor radon accumulations. Epidemiological studies published by the World Health Organisation (WHO) and the International Agency for Research on Cancer (IARC) have already scientifically proven the carcinogenicity of these gases. The presence of radon indoors is mainly due to the pressure difference between the external and internal environment; in fact, the temperature difference results in a lower air pressure inside the room, which leads to suction of the gases from the outside to the inside. Radon emitted from the ground is sucked upwards, rises to the lower floors and diffuses into the rooms used on a daily basis. If the presence of radon gas inside the house is identified or simply assumed, the most effective intervention to reduce its hazardousness and consequently reduce the risk to human health is to install a well in the basement of adjacent rooms to allow the radon gas (which is heavier than air) to enter the house, then collect it and transport it to a safe distance away through an AXR ventilator. To achieve this, it is always recommended that qualified installers are contacted to ensure that the correct fan size is selected.
