The natural noble gas occurs <br />in the earth's soil and penetrates to the surface through cracks and <br />crevices. It is formed when uranium and thorium decay into polonium, <br />bismuth and lead in the soil. In the lungs, these by-products cause <br />pathological changes: Cancer. <br />Radon is hardly a problem in the fresh air. It becomes dangerous in <br />enclosed spaces such as cellars or basement flats. There, the load <br />increases rapidly and becomes a potential danger. Radon occurs <br />throughout Germany, but there are particularly contaminated areas. <br />There, builders and employers must take special measures. But it is also <br />imperative to make provisions for yourself and your family in your own <br />home.</p> <p>4</p> <p>schomburg.com</p> <p>Effects of radon on health <br />Risks and statistics</p> <p>Why is radon so dangerous? Exposure often goes unnoticed - the noble gas is absolutely <br />odourless and tasteless. Radon is inhaled with the indoor air and decays in the lungs. <br />There, the decay products “irradiate” the lung cells with dangerous radioactive radiation <br />and, in the worst case, cause lung cancer. <br />Official statistics assume about 1,900 radon deaths per year in Germany. Greater, of <br />course, is the number of those who struggle with persistent severe health problems. In fact, <br />radon in homes is the most common cause of lung cancer after smoking; across Europe, <br />one in 50 people is diagnosed with lung cancer. Cancer deaths caused by the noble <br />gas.</p> <p>For more information on health risks, the current <br />state of radon research and possible radon cures, <br />please visit the website of the BfS - Federal Office <br />for Radiation Protection.</p> <p>schomburg.com</p> <p>5</p> <p>Radon distribution in Germany <br />Precautionary zones and exposure levels <br />Radon occurs throughout Germany, but there are particularly affected areas. Since <br />the beginning of 2021, these regions have been designated as so-called “precautionary <br />areas” by the Federal Office for Radiation Protection. Parts of Bavaria, BadenWürttemberg, Thuringia and Saxony are particularly affected. Taking precautionary <br />measures in the remaining provinces increases protection and improves safety. <br />This map roughly shows the “underground radon concentration” at a depth of one metre <br />in Germany. A concrete radon occurrence can only be determined by explicit <br />measurement.</p> <p>Bq/m3 = Becquerel per cubic metre <br />Source: Federal Office for Radiation Protection (BfS)</p> <p>Do you live in a risk area? <br />Here you can find the radon <br />precautionary areas in Germany.</p> <p>6</p> <p>schomburg.com</p> <p>Radon in indoor spaces <br />Legal basis <br />Why is radon so dangerous, especially indoors? The light noble gas rises continuously. <br />It penetrates through the smallest cracks in the masonry, inadequately sealed joints or pipe passages, especially <br />into basement rooms, basement flats or buildings built on slopes. Of course, clay or natural stone floors offer little <br />resistance. But even fundamentally watertight floor slabs can develop cracks over time and then become a risk. <br />Over time, the gas concentration increases, especially if the room is not ventilated. Since the dose makes the <br />poison, the legislator has prescribed the limit of 300 Becquerel as an annual average. But this is not advisable. <br />The World Health Organisation WHO considers a maximum exposure of 100 becquerels to be acceptable. <br />Dosimeters can be used to measure radon exposure. These devices are already available in a “passive” version <br />from about 30 to 50 euros. Somewhat more accurate are active measuring devices that store the data digitally <br />and can be analysed with a computer. However, these dosimeters are also more expensive to purchase. Since <br />the annual mean value is always of decisive importance, the more accurate and less error-prone active dosimeters <br />are highly recommended.</p> <p>In principle, the German Radiation Protection Ordinance , which goes back to an EU directive, regulates the handling <br />of radon. The Radiation Protection Ordinance contains specific information on what must be observed.</p> <p>Private buildings</p> <p>Commercially used buildings</p> <p>For new buildings in precautionary areas, building <br />owners must ensure that no radon can penetrate. <br />Architects and planners have a duty to support them <br />in this and to provide the appropriate solutions. If it is <br />a renovation of an old building, there are no legal <br />requirements. Indeed: No one wants to risk their <br />own health and that of their fellow residents lightly.</p> <p>In the precautionary areas, employers must regularly <br />monitor radon concentrations - whether in old or <br />new buildings. The annual average exposure must <br />not exceed 300 Becquerel. In any case, it makes <br />sense to protect the health of its workers as much as <br />possible with constructional measures.</p> <p>Further information on the Radiation Protection Act <br />and the Radiation Protection Ordinance can be <br />found on the website of the BfS - Federal Office for <br />Radiation Protection.</p> <p>schomburg.com</p> <p>7</p> <p>Radon prevention systems <br />For new builds and renovations</p> <p>Radon can be reliably and continuously excluded from buildings. The simplest option: regular airing. <br />But that also has its pitfalls. For the sake of one's health, one has to be very disciplined about airing <br />again and again - and at the same time ruins the energy balance of one's house. There are also <br />elaborate technical solutions such as active extraction systems or “radon wells” that can reduce <br />concentrations as well. The easiest way is still to take suitable precautionary measures to ensure that <br />radon does not enter a building in the first place. Efficient system solutions such as those from <br />SCHOMBURG offer safety in both new buildings and renovations. And over the long term at that. <br />On the following pages, we present our radon-proof products as well as safe system solutions for new <br />construction and renovation.
