Radon protection

Radon is a noble radioactive gas, odorless and colorless, produced by the radioactive decay of radium.

Radon is present in different quantities in the indoor air of all buildings and mainly comes from the soil and, to a lesser extent, from the building materials (especially in case of thick walls).

Many epidemiological studies have found that continuous exposure to radon increases the risk of developing a lung cancer. The extent of the risk increases with the radon concentration level and with the duration of exposure. With the same exposure to radon, smokers are much more at risk than non-smokers, due to sinergy effects of radon and cigarette smoking. In Italy, exposure to radon is responsible (according to estimates by the Italian National Institute of Health (ISS) of more than 3000 cases (link to the Italian website) of lung cancer every year.

Since 2005, the ISS has coordinated the Italian National Radon Plan (promoted in 2002 by the Ministry of Health) and manages the National Radon Archive.

A new National Radon Action Plan is in a advanced stage of preparation. This new plan is required by the Legislative Decree 101/2020 that has transposed the European Directive 2013/59/Euratom on basic safety standards for protection from ionizing radiation.

As required by the Legislative Decree 101/2020 (art. 14, par. 1), the ISS provides information to the population about:

These and many other information on radon (actually available since 2013 in the framework of the Italian National Radon Plan) can be found on https://radon.iss.it (link to the Italian website) and they will be updated regularly. 
Protection from radon is one of the themes of the collaboration of the National Center for Radiation Protection and Computational Physics of ISS with the World Health Organization (WHO), within the WHO Collaborative Centre “Radiation and Health”, which is active since 2018.

Back Archivio Nazionale Radon

I dati di misurazioni di concentrazioni di radon già inseriti e validati nell’Archivio Nazionale Radon (ANR) sono oltre 50000 (aggiornato al 2018-2019), di cui circa 35000 relativi alle abitazioni, 8000 relativi a edifici scolastici e 8000 relativi a luoghi di lavoro.
In particolare nell’ANR sono presenti dati di concentrazione di radon in abitazioni presenti in oltre 3500 comuni italiani, nella metà dei quali sono state effettuate misure in almeno 5 abitazioni.
Alla pagina “quanto radon c'è in Italia nelle abitazioni: tabelle riassuntive” sono disponibili, per ciascuna Regione e Provincia Autonoma italiana, le tabelle riassuntive sui dati di radon per i comuni con almeno 5 abitazioni misurate.
Si ribadisce che informazioni su misurazioni effettuate anche nello stesso Comune non permettono di stimare adeguatamente la concentrazione di radon in uno specifico edificio/abitazione.
Per conoscere la concentrazione di radon nella propria abitazione è necessario procedere a misurazione diretta per mezzo di dispositivi e protocolli adeguati, informazioni su come eseguire la misura sono disponibili alla pagina “come si misura il radon
