Since <br />the beginning of 2021, these regions have been <br />designated as ‘precautionary areas’ by the Federal <br />Office for Radiation Protection. Parts of Bavaria, <br />Baden-Württemberg, Thuringia and Saxony are <br />particularly affected.</p> <p>The implementation of precautionary measures in the <br />other federal states increases protection and improves <br />safety. <br />This map shows, in broad terms, the ‘subsurface radon <br />concentration’ at a depth of one metre in Germany. <br />A specific radon occurrence can only be determined <br />by taking an explicit measurement.</p> <p>WHAT IS RADON? <br />THE INVISIBLE DANGER <br />Radon is invisible, odourless and a threat to our health. But what exactly <br />is radon, why is it so dangerous, where is it found and, above all, how <br />can you protect yourself from it? <br />Radon is a dangerous radioactive gas – in Germany, it <br />is one of the main causes of lung cancer. This naturally <br />occurring noble gas is found in the ground and seeps <br />to the surface through cracks and crevices. It is formed <br />when uranium and thorium in the soil decay into <br />polonium, bismuth and lead. These decay products <br />cause pathological changes in the lungs.</p> <p>However, it is also essential to take precautions for <br />yourself and your family in your own home.</p> <p>Radon is hardly a problem in the open air. It becomes <br />dangerous in enclosed spaces such as cellars or <br />ground-floor flats.</p> <p>There, the decay products "irradiate" the lung cells with <br />dangerous radioactive radiation and, in the worst-case <br />scenario, cause lung cancer.</p> <p>There, radon levels rise rapidly and become a potential <br />hazard. Radon is found throughout <br />Germany, although there are areas with particularly <br />high levels. In these areas, building owners and <br />employers must take special measures. <br />4</p> <p>Why is radon so dangerous? Exposure often goes <br />unnoticed – the noble gas is odourless and tasteless. <br />Radon is inhaled along with indoor air and decays in <br />the lungs.</p> <p>Do you live in a high-risk area? <br />You can find the radon risk areas in <br />Germany here. <br />Bq/m³ = becquerels per cubic metre <br />Source: Federal Office for Radiation Protection (BfS)</p> <p>5</p> <p>Further information on the Radiation Protection Act and the <br />Radiation Protection Ordinance can be found on the website of the BfS – Federal Office for Radiation Protection.</p> <p>RADON IN INDOOR SPACES <br />LEGAL BASIS <br />In principle, the Radiation Protection Act, which is based on an <br />EU directive, governs the management of radon. The specific <br />requirements are set out in the Radiation Protection Ordinance. <br />Radon is particularly dangerous indoors because this <br />radioactive noble gas rises from the ground and enters <br />the building through cracks, joints or pipe penetrations <br />– especially in basements, ground-floor levels and on <br />sloping sites. Clay and natural stone floors offer little <br />protection, and even sealed floor slabs can develop <br />leaks over time..</p> <p>300 Becquerel/m³. However, the WHO recommends <br />a maximum of 100 Becquerel/m³, as even lower levels <br />increase the health risk. <br />Radon levels can be measured using radon dosimeters: <br />passive devices are available from around 30–50 euros, <br />whilst active measuring devices are more expensive but <br />more accurate and store the data digitally.</p> <p>In the absence of ventilation, radon concentrations rise <br />continuously. As the absorbed dose is the decisive <br />factor, the legal limit is set at an annual average of</p> <p>As the annual average is the key factor, active <br />dosimeters are particularly recommended.</p> <p>6</p> <p>Private buildings <br />In the case of new-builds in radon-prone areas, <br />developers must ensure that radon cannot enter the <br />building. Architects and planners have a duty to <br />support them in this and to provide the appropriate <br />solutions.</p> <p>Commercial buildings <br />In areas designated as requiring preventive <br />measures, employers must regularly monitor radon <br />concentrations – regardless of whether the building <br />is old or new. The annual average concentration <br />must not exceed 300 becquerels.</p> <p>Where the project involves the refurbishment of an <br />existing building, there are no legal requirements. <br />However, nobody wants to recklessly put their own <br />health and that of their housemates at risk.</p> <p>It is certainly advisable to take structural measures <br />to protect the health of employees as effectively <br />as possible.</p> <p>7</p> <p>Products <br />AQUAFIN®-RB400</p> <p>Rapid mineral-based building waterproofing <br />• Flexible polymer-modified thick coating (FPD) <br />• Mineral-based sealing slurry (MDS) <br />• Bitumen-free <br />• Rapid, reactive through-drying <br />• Improved crack-bridging properties even at low temperatures (−5 °C) <br />• Very low emissions – EMICODE® EC 1PLUS</p> <p>COMBIDIC-2K-PREMIUM <br />Reactive two-component bituminous thick coating (PMBC)</p> <p>RADON PREVENTION SYSTEMS <br />FOR NEW BUILDS AND REFURBISHMENTS <br />Efficient system solutions such as those from SCHOMBURG provide <br />reliability in both new-build and refurbishment projects. They do so for <br />the long term. <br />Radon can be reliably and permanently removed from <br />buildings. The simplest way is to ventilate regularly. <br />However, this has its drawbacks. For the sake of your <br />health, you have to be very disciplined about ventilating <br />time and again – and at the same time, you end up <br />ruining your home’s energy efficiency.</p> <p>There are also sophisticated technical solutions, such as <br />active extraction systems or ‘radon wells’, which can <br />also reduce concentrations. The simplest approach is <br />still to take appropriate preventative measures to ensure <br />that radon does not enter a building in the first place.</p> <p>• Waterproofing of structural elements in contact with the ground, such <br />as basement walls and floor slabs <br />• For water exposure classes DIN 18533 W1.1-E, <br />W1.2-E, W2.1-E, W3-E, W4-E <br />• Seamless and joint-free structural waterproofing that bridges cracks</p> <p>KSK-Abdichtungsbahn <br />KSK-Abdichtungsbahn <br />Cold-applied self-adhesive bituminous membrane <br />• Waterproofing of wall surfaces and floor slabs in contact with the ground <br />in accordance with DIN 18533-2 <br />• For water exposure classes DIN 18533 W1.1-E, W1.2-E and W4-E <br />• As a waterproofing layer beneath screeds in accordance with DIN 18534-2, <br />water exposure classes W0I to W2-I</p> <p>ASODUR-SG2 <br />Specialised epoxy resin primer / oil and vapour barrier</p> <p>The Heinze Download Manager also offers <br />you an extensive selection of suitable <br />tender documents.</p> <p>8</p> <p>• Special primer for oily, but previously cleaned, concrete substrates <br />• Low-solvent, moisture-tolerant, two-component epoxy resin <br />• Excellent adhesion to damp concrete substrates</p> <p>9</p> <p>Radon prevention systems | New building</p> <p>Radon prevention systems</p> <p>Products</p> <p>External waterproofing of wall and floor <br />junctions in new-build properties</p> <p>ASOCRET-M30 <br />Waterproof multi-purpose mortar up to 30 mm <br />• High stability <br />• Fast-setting <br />• Sulphate-resistant <br />• Water-repellent</p> <p>4 <br />1</p> <p>ADF® -Rohrmanschette <br />Epoxy resin barrier primer for damp substrates, thixotropic</p> <p>3</p> <p>• Tear-resistant <br />• Highly elastic <br />• Water-impermeable <br />• Compatible with bitumen</p> <p>AQUAFIN®-RB400</p> <p>Reactive two-component bituminous thick coating <br />• Fast-curing and can be loaded early <br />• Highly wear- and abrasion-resistant against pneumatic, solid rubber <br />and Vulkolan tyres <br />• Permeable to vapour <br />• Resistant to chloride and CO²</p> <p>2</p> <p>1</p> <p>Substrate (concrete/masonry)</p> <p>2</p> <p>Mineral-based coving, e.g. ASOCRET-M30</p> <p>3</p> <p>Pipe penetration -
