According to thè ANPA
(National Agency for Environmental Protection)
thè presence in Italy of radon, a gaseous radioactive element derivingfrom thè decay ofuranium, isfar above thè average of the resi of thè world. It's presence is ubiquitous and is not only concentrated in thè risk areas of mines. The gas is formed in thè subsoit but accumulates in poorly ventilated parts of thè home: cellars, basements and attics. The ease with which it con unwittingly be inhaled represents thè greatest riskfactor. The alpha partides emitted by thè atom of radon, which decays into polonium, have great kinetic energy: they con affect thè cellular structures of thè larynx, trachea, thè bronchi and lungs, damaging thè genette code and triggering on tumoral degenerative process
