HEALTH EFFECTS
The World Health Organization has classified radon in Group 1, which lists the 75 substances to date are classified as carcinogenic to humans.
Radon, a noble gas that is inert and therefore, is rapidly exhaled, while its decay products, which are solids remain on the inner walls bronchial apparatus. Here and make alpha particles, producing cell damage broncho-pulmonary, including DNA and such damage may progress to cancer or tumore.Dopo smoking is the main cause of cancer polmonare.Da Hence the need to investigate the premises where the presence of people may be important in terms of radiation exposure.
RULES
Although there is no legal obligation in this regard, public interest is to quantify the concentration of radon in dwellings and in rooms where you spend most of tempo.Il own risk depends on the concentration and duration of exposure. That is, if you live in an environment where the radon level is more likely to be more, as if it remains for longer in contact with radiation. E 'therefore important to be aware of health impacts from exposure to this radioactive gas, and once known the concentration of radon, implement remediation and appropriate behavior can significantly reduce the risk from this sostanza.Inoltre certification of the absence of radon gas (especially in basements) in the home could become a key parameter for the purchase / sale of both to ensure the healthiness of the premises, and be sure not to expose your loved ones substances harmful to health.
The Decree 230/95, as amended by Legislative Decree 241/00, agreed that by March 1, 2004 all workplaces must be subjected to underground instrumental measurement of the concentration of radon gas.
HOW TO MEASURE THE RADON?
Because radon and 'a colorless, odorless gas, its effects are not directly perceptible by the senses of man. The instruments for the measurement of radon can be of two types: Electret (formed by an electrostatically charged Teflon disk, are ideal for measurements in the short term (15 days) and are suitable for measurements in private homes) or nuclear tracks (CR39, suitable for measurements from 1 to 12 months). dosimeters, at the end of the period are collected and taken to a qualified laboratory where they are analyzed.
INTERVENTION OF A REMEDY
· Dilution of radon through ventilation and increased air recirculation
· Compile by impermeable barriers, sealing of gaps, cracks and fissures in drainages
· and removal of soil through mechanical ventilation ducts
· Ventilation natural or forced the crawlspace

GROSSETO. Il professor Giorgio Curzio, ordinario di misure nucleari all'università di Pisa, aveva lanciato l'allarme 6 anni fa: «Garfagnana, Colline Metallifere, Amiata e colline del tufo hanno un nemico invisibile che non va ignorato. Si chiama radon, è un gas radioattivo naturale che trasuda dal suolo nelle zone con rocce di origine volcanic activity. The institutions can not underestimate the scale. " Professor Giorgio Curzio it looks like he was right. Recently, the Tuscan Region has organized a conference on the presence and dangers of radon. Now the 28 municipalities of the province of Grosseto are receiving detailed reports on monitoring carried out by ARPAT during the period between 2007 and 2009. In Maremma have been affected by the research among 1,065 local homes and places of work or aggregation. The picture that emerges is summarized in the table. The limit beyond which scientists and doctors believe that radon is dangerous to health is 300 Bq per cubic meter, but already above 200 becquerels should take action to clean up a room, since Epidemiological studies have shown that the risk of developing cancer is low but not zero, even for concentrations of radon do not exceed 200 Bq / cu m, which are frequent, for example, in homes that are located in the historic centers of Arcidosso, Santa Fiora , Castel del Piano, Pitigliano. The research work done by ARPAT, as well as private homes, has affected laboratories, public houses, schools, churches, theaters, parking garages. From the data published it is clear that the most common "clean" are mainly coastal ones (Grosseto, Follonica, Castiglione, Scarborough), that is, with newly built houses, schools, industrial zones and craft new ones. A radon risk Santa Fiora, Sorano, Capalbio, Isola del Giglio, Pitigliano, but Massa Marittima . All municipalities with residential units on ancient volcanic rocks, tuff or rhyolite. "Workplaces have lower values \u200b\u200bof the houses - a geologist confirmed - because they generally are located outside the volcanic areas in the valley, the alluvial plains or the schools are new buildings, raised from the ground. At first glance it may seem strange to the high value of the houses examined inherent in Massa Marittima, because the center is not over volcanic rocks, but on bases of limestone. The explanation probably lies in the high cracking of cavernous limestone, allowing the gas to be traced back well. " 'In building codes for areas with higher concentrations - explain Angiolucci Silvia and Gabriele Rossi a pamphlet distributed by ARPAT - will be included in future directions for the construction of buildings in order to restrict the entry of radon. The main steps during the design relate to the isolation of the ground, the ability to ventilate the cellars, the sealing of the access routes of gas, making it waterproof the floors, and the isolation of cracks and pipes. The choice of building materials with low levels of natural radionuclides reduces concentration, even if the materials are not enough to determine very high levels. " Returning to the details for monitoring Arpat property and the workplace are sensitive data, encrypted and not published. Who saw them, however, speaks of many buildings, sometimes unsuspected, which have values \u200b\u200balarming, with remedial measures may soon be required to municipalities concerned.
WHAT 'THE RADON
Radon is a natural radioactive gas, no odor, color, flavor, extremely volatile. And 'one of the most important components of naturale.Viene radioactivity produced by radioactive decay of natural uranium. Is emanating from the land (especially by lavas, tuffs, pozzolana) from the rocks and to a lesser extent by water, which can dissolve (it may be present in groundwater).
E 'also its presence known in some building materials.
The road generally runs to get inside a building that is flowing through cracks and small holes in the cellars and basements.
This is due to a difference in pressure between the soil and the enclosed space, being in depression than the outside. If the base has a mud floor radon penetrates easily, if the floor is concrete, radon enters through the cracks formed over time, along pipes or through the joints between the walls.
Other situations that facilitate a high concentration of radon are: - walls and floor in direct contact with the ground or poorly-insulated room with very thick walls to the upper floors and built with crushed stone (found mainly in the Alto Adige) - underground walls built open spaces with bricks foratiNegli its concentration is very low as it is diluted by air currents, in confined environments, however, accumulates and reaches high concentrations. Hence the need for careful assessment, as people spend more than 80% of the time living in environments chiusi.I rooms where you can more easily found high concentrations of radon are buried and basements, even though there have been cases in which it was detected a strong presence even on the second floor (this depends on the transport and escape routes that meets the gas).
