4 1. PURPOSE OF PREVENTION The purpose of radon preventive measures is to secure that radon concentration in every room of the habitable space is lower than the reference level or design value. Reference level is prescribed by legislation within the range Bq/m 3. Design value is prescribed by future owner (below reference level). Fulfilment of this objective is verified by measurement of radon concentration under the ventilation rate satisfying the minimum hygiene requirements.
5 2. FACTORS INFLUENCING THE DESIGN Radon potential of a building site Position of the house in the soil Location of habitable rooms Underfloor heating PREVENTIVE MEASURES Type and depth of foundations Workmanship, experience of the contractor Sub-floor layers of high permeability Method of ventilation Technical standards, building codes
6 2.1 Radon potential of a building site Availability of radon in the soil - radon concentration in the soil air Ability of radon to migrate in the soil - soil permeability Usual categories: low, medium, high Classification can be performed for: particular building site urban area, planning area municipal area Classification can be based on: geological data indoor radon data
7 2.1 Radon potential of a building site Example from CZ - classification into risk areas based on geological data Soil gas radon concentration and soil permeability are measured directly on a building site. Radon risk category is determined according to the following table. Radon risk Soil gas radon concentration (kbq/m 3 ) high vysoké High vysoký risk riziko index Medium střední riziko index risk Low/Medium přechodná oblast risk Low nízké nízký riziko index risk medium low Soil permeability low medium high
8 2.1 Radon potential of a building site Example - classification into risk areas based on indoor radon data Areas are identified by % of houses with indoor radon concentration above the reference level 200 Bq/m 3, for example: < 1 % low risk area 1 10 % medium risk area > 10 % high risk area
9 2.1 Radon potential of a building site Example from UK - classification into risk areas based on combination of indoor radon data and geological data The mapping database holds risk data by postcode. Indicative maps based upon 1km grid directly show the type of protection none, basic, full.
10 2.2 Position of the house in the soil Underground water House on a ventilated crawl space House on an artificially created fill of low permeability House founded under the water table level Low risk of radon penetration from the soil into a house
11 2.2 Position of the house in the soil Permeable soil Permeable soil Permeable soil House on a ground House on a slope House with a cellar High risk of radon penetration from the soil into a house
12 2.3 Location of habitable rooms On the floors that are in direct contact with the soil On the upper floors without contact with the soil
13 2.4 Type and depth of foundations Gap Reinforcement Crawl space Gaps Reinforced slab Waterstop
14 2.5 Risk factors Underfloor heating Increases pressure difference Flooring Underfloor heating Thermal insulation Blinding concrete Course gravel Sub-floor layers of high permeability Subsoil Radon reservoir
15 2.6 Method of ventilation Ventilation systems: natural, mechanical, hybrid In modern buildings it is not possible to rely on infiltration through airtight windows to satisfy ventilation requirements. Buildings should have a reliable ventilation system. Ventilation system influences ventilation rate and sometimes also radon supply rate and thus indoor radon concentration. Radon concentration C Ventilation rate J n. V Radon supply rate Interior air volume
16 2.7 Technical standards, workmanship Technical standards, building codes Dealing with protection of buildings against radon All other relevant standards Radon preventive measures are part of the building structure. They must be evaluated completely, particularly with regard to building physics, thermal protection of buildings, building waterproofing, etc. Workmanship, skills, experience of the contractor
17 3. PRINCIPLES OF PREVENTIVE MEASURES 3.1 Separating a building from the soil Building on pillars Building on crawl spaces
18 3. PRINCIPLES OF PREVENTIVE MEASURES 3.2 Ensuring air-tightness of the substructure Radon barrier material placed over the entire surfaces of walls and floors in contact with the soil This approach is not effective in existing houses!!!
19 3. PRINCIPLES OF PREVENTIVE MEASURES 3.3 Changing the pressure difference between the soil and the house by soil or air gaps depressurization Fan generating underpressure under the house or within the air gap is installed if natural draught is not sufficient.
20 3. PRINCIPLES OF PREVENTIVE MEASURES 3.4 Diluting indoor concentration by increased ventilation Efficient ventilation systems are: mechanical exhaust air ventilation with outdoor air inlets mechanical supply and exhaust air ventilation with heat recovery
21 3. PRINCIPLES OF PREVENTIVE MEASURES 3.5 Combining radon-proof insulation + subslab depressurization Radon-proof insulation Drainage layer of coarse gravel Roof fan or rotating cowl to improve the draught Vertical exhaust PVC pipe Interconnecting PVC pipe Perforated flexible pipes - Floor layers - Radon-proof membrane - Bonding primer or geotextile - Blinding concrete - Geotextile - Coarse gravel with perforated pipes - Subsoil
22 3. PRINCIPLES OF PREVENTIVE MEASURES The type and the degree of protection depends on the radon risk of the building site and other factors influencing the design. Radon risk Measures Principle of protection Low Tradition design No special protection is required. No open connections from the building to the ground. Medium High Standard (basic) radon protection Radon-protecting design Increased (full) radon protection Radon-proof design The basic measure is an impermeable substructure: reinforced concrete radon-proof insulation Impermeable substructure is usually combined with: sub-slab depressurization air gaps ventilation
23 3.7 Example of the Czech prevention Radon index Low Medium or high Principle of protection Water resistant construction waterproof insulation or waterproof reinforced concrete construction Water resistant construction or radonproof insulation in dependence on the type of a building and type of ventilation
24 3.7 Example of the Czech prevention Houses with naturally ventilated habitable rooms on the floors in direct contact with the soil Protection = radon-proof insulation Combination with soil or air gap ventilation must be applied, if: Soil gas radon concentration exceeds: 60 kbq/m 3 in highly permeable soils, 140 kbq/m 3 in soils with medium permeability, 200 kbq/m 3 in soils with low permeability. Highly permeable gravel layer is placed under the house Floors resting on the soil are equipped with under-floor heating
25 3.7 Example of the Czech prevention Houses with habitable rooms located on the upper floors Protection = water resistant construction water-proof insulation or waterproof reinforced concrete construction Conditions that must be satisfied: a reliable ventilation rate is ensured in any place of the contact floor the ceiling above the contact floor is airtight with sealed services penetrations the entrances to the contact floor from the other floors are ensured with doors of a good air-tightness and equipped with a door closer
26 3.7 Example of the Czech prevention Houses equipped with mechanical ventilation (in all habitable rooms of the contact floor) Protection = water resistant construction water-proof insulation or waterproof reinforced concrete construction Houses on crawl spaces Protection = crawl space ventilation; water-proof or radon-proof courses in the floor above the crawl space applied only under defined conditions
27 3.8 Example of Norwegian prevention Approach based on radon risk evaluation. 4 Low radon risk general preventive measures: Prevention of leakage at critical points radon barriers and / or durable sealants Ground ventilation / depressurisation Balanced ventilation in the building 4 Medium or high radon risk additional, extended measures Radon membranes with thickness > 0.3mm Extended ground ventilation / depressurisation Choice of radon tight construction and building materials

32 4. GENERAL RECOMMENDATIONS Surface finishing around the building should be permeable Backfill around the building should be permeable Constructions on which radon-proof insulation will be applied should be in simple shapes Non-ventilated permeable layers under the building should be avoided
33 4. GENERAL RECOMMENDATIONS Construction of installation shafts should have good airtightness, pipe penetrations should be sealed Ceilings above the contact floors should have good airtightness, pipe penetrations should be sealed Boiler or other device consuming indoor air Direct supply of outdoor air for boilers and furnaces in order to minimize underpressure in contact floors
34 4.

35 5. AIR-TIGHT SUBSTRUCTURE Airtightness is ensured by application of radon proofinsulation (RPI) over the entire surfaces of walls and floors in contact with the soil. RPI fulfils also the function of waterproof insulation it is selected from standard waterproof materials RPI should have verified radon barrier properties Durability of RPI should correspond to the lifetime of the building
36 5.1 Position of RPI in the substructure Above slab application Sub slab application - Floor layers - Protective layer - Radon-proof insulation - Bonding primer or geotextile - Blinding concrete - Leveling layer - Subsoil - Floor layers - Blinding concrete - Protective layer - Radon-proof insulation - Geotextile - Leveling layer - Subsoil
37 5.2 Properties of RPI RPI must withstand predictable deformations and movements of the substrate and foundation construction Tensile strength, elongation, tear resistance and other material and physical parameters must be taken into account when designing radon-proof courses RPI must be resistant to soil corrosion caused primarily by microbiological agents and chemical compounds occurring in the soil RPI must have low radon diffusion coefficient
38 5.3 Testing of barrier properties of RPI Reasons for testing Great amount of tanking materials of different chemical composition Difficult selection of membranes with barrier properties against radon Tested quantity Radon diffusion coefficient is a material property that determines diffusive transport it seems to be a convenient parameter for testing of barrier properties

62 6. SUB-SLAB DEPRESSURIZATION The principle of SSD methods is to change the pressure difference between the soil and the house, i.e. to lower the air pressure in the soil under the house compared to the pressure indoors and to dilute the subsoil radon concentration. The pressure is lowered by means of the natural draft occurring as a result of the stack effect and wind forces, or by a fan.
63 6. SUB-SLAB DEPRESSURIZATION Systems suitable for new buildings Radon sumps Network of flexible perforated pipes inserted into the drainage layer Combination of the above stated measures
64 6. SUB-SLAB DEPRESSURIZATION General design rules The form of soil depressurization depends on: - ratio of underfloor layer and soil permeabilities k d /k s - airtightness of floors - type and geometry of foundations A sump or a perforate pipe must be laid in every subfloor space surrounded by strip foundations. In order to minimize the occurrence of negative side effects (drying and freezing of the subsoil) the distance of a sump or a pipe from perimeter foundations should be at least 0,5 m.
65 6. SUB-SLAB DEPRESSURIZATION General design rules Passive extraction of the soil air using vertical exhaust pipe terminating above the roof should be preferred. Each passive system must enable the supplementary assembly of a fan to increase the system s efficiency. To avoid re-entering of radon into a building, the outlets of the exhaust pipes should be located at least 2 m away from windows, vent holes and inlets of HVAC systems.
66 6. BEHAVIOUR OF SSD SYSTEMS Highly permeable soil Upper layer high permeability, lower layer low permeability Rn concentration Rn concentration Air flow Air flow Air pressure Air pressure
67 6.1 Sump systems Sump is a free air space below the building s floor with a volume of at least 10 dm 3 Sump is always created in a drainage layer of coarse gravel One sump is effective over a floor area of approx m 2 Sump should be preferably placed into the centre of the underfloor space If the underfloor space is divided by strip foundations into several compartments, sump must be placed into each compartment.

73 6.2 SSD systems with perforated pipes Diameter of perforated pipes: mm for natural ventilation mm for forced ventilation Pipes are placed into a continuous drainage layer with a minimum thickness of 150 mm created from coarse gravel fraction of 16/32 mm. Pipes are laid in every section bordered by the strip foundations. Mutual distance between perforated pipes is around 4 m Perforated pipes ensure better pressure distribution than sumps, therefore they are more convenient for highly permeable soils.

77 6.2 SSD systems with perforated pipes Ventilation merely to the perimeter walls is unacceptable
78 6.2 SSD systems with perforated pipes
79 6.3 Fans suitable for SSD systems Fans must be able to: transport soil air with a relative humidity from 80 % to 100 % resist the flow of condensed water resist the increased dustiness of the transported air

82 6.3 Fans suitable for SSD systems Typical installations of fans Wall type of a paddlewheel fan Risk of icing on the external surface of the wall from condensed water vapour
83 6.3 Fans suitable for SSD systems Roof fan Ventilating head Exhaust pipe In line paddlewheel fan
84 7. AIR GAPS DEPRESSURIZATION The principle of an air gap depressurization is to lower the air pressure in the gap that is provided along walls and floors in contact with soil. The pressure is usually lowered by means of a fan.
85 7. AIR GAPS DEPRESSURIZATION The air gap must be continuous throughout the entire area of the constructions in contact with the soil. Active ventilation is preferred. Active ventilation is executed without any vent holes delivering external air into the gap. Passive ventilation must be always executed using vertical exhaust pipes. Passive ventilation merely to the perimeter walls is unacceptable. Passive ventilation with indoor air is not allowed.
86 7. AIR GAPS DEPRESSURIZATION Air gaps construction Plastic membranes with dimples Corrugated steel, cement-fibre or plastic sheets Preformed plastic components

93 8. HOUSES ON CRAWL SPACES 8.6 General principles The entrance to the crawl space is recommended to be located from outside Water and wastewater pipes passing through the crawl space are to be fitted with thermal insulation When ventilating the crawl space with outdoor air, outer walls and the floor above the space must be equipped with thermal insulation When ventilating the crawl space with indoor air, outer walls and the ground surface must be provided with thermal insulation

96 9. VENTILATION SYSTEMS The principle of ventilation is to dilute radon concentration by increasing the ventilation rate Radon concentration C J n. Radon supply rate Ventilation rate V Interior air volume
97 9. VENTILATION SYSTEMS The preference should be given to systems that are balanced (amounts of supply and exhaust air are the same), or to systems creating a slight underpressure. Systems creating overpressure are not recommended in countries with cold climates (condensation in walls problems). If energy saving is important demand controlled ventilation systems should be used. Required amount of fresh air is provided only when it is needed (when the rooms are occupied). However, the ventilation should be functioning at reduced speed the rest of the time.
98 9. VENTILATION SYSTEMS 9.1 Natural ventilation supported by outdoor air inlets Types of outdoor air inlets: Outdoor air inlet Window registers for installation in window frames Wall registers for installation in external walls
