X-ray examination rooms require structural radiation shielding to adjacent rooms.The rules for the application of structural radiation protection (useful and stray radiation) are defined in DIN 6812.The basis of all structural measures for X-ray protection is the radiation protection plan, which has to be created by the manufacturer of the X-ray unit. The thickness of the required radiation shielding depends on the tube voltage of the device type used (depending on the medical application) and is stated for lead as the shielding material. The higher the tube voltage, the thicker the necessary layer of lead.

For shielding layers made of other materials, the protection effect is stated as lead equivalence. The lead equivalence of a material specifies the lead thickness in mm to which the shielding effect of the material is equivalent. Information on lead equivalences of various building materials is listed in DIN 6812, table 18.

X-Ray shielding With drywall systems

Heavy concrete used previously for X-ray shielding in hospitals and medical practices can now easily and efficiently be replaced by Knauf X-Ray Shielding Systems. Knauf X-Ray Shielding Systems are applied in the fields of X-ray diagnostics and low-power X-ray therapy. Radiation protection is provided in the form of shielding, room-enclosing components with specific lead equivalences of the used materials. However, due to their weight, the gypsum boards with lead sheet lamination used so far are difficult to apply and require extreme care during installation in order to provide flawless radiation protection.

■ Intermediate values can be interpolated in linear fashion. Calculation of lead equivalence acc. to DIN 6812. ■ One layer of Safeboard is sufficient for X-ray shielding in mammography (35 kV) screening ■ The combination of Safeboard with lead sheet laminated gypsum boards is possible.

Planning aid for individual X-ray shielding solutions with Safeboard

The lead equivalence of Safeboard X-Ray Shielding Partitions is in-creased by 0.1 mm Pb if an additional layer of 12.5 mm thick Diamant boards is applied on both sides.

mm Pb ... is the unit of lead equivalenceAn exemplary material of lead equiva-lence 1 mm Pb (Pb = chemical symbol for lead) provides the equivalent shielding ef-fect as 1 mm thick lead sheet.

Comparison:Various building materials with required system thickness at 1 mm lead equivalence and tube voltage 100 kV

Benefits of drywalling systems ■ Ideal solution for subsequent construction of X-ray shielded areas in existing buildings.

■ Installation of cabling in the stud frame is possible without reduction in the X-ray shielding.

■ No structural consideration required when planning the support structure in comparison to solid walls, as it only needs to be considered as a lightweight partition.

For cladding thicknesses: ■ 1x 12.5 mm Safeboard ■ 1x 12.5 mm Safeboard + 1x 12.5 mm Diamant ■ 2x 12.5 mm Safeboard ■ 2x 12.5 mm Safeboard + 1x 12.5 mm Diamant ■ 3x 12.5 mm Safeboard

Safeboard X-Ray Shielding BoardsThe Knauf Safeboard had been developed to minimize the additionally required effort for the application of X-ray shielding systems compared to conventional drywall systems. Together with the Safeboard-Spachtel filler, this X-ray Shielding Board can be applied much like a regular gypsum board and simultaneously offers all the technical characteristics (sound insulation, fire resistance) of a conventional gypsum board.Thus, fire protection requirements of suspended X-ray shielding ceilings can also be met.

X-Ray shielding With Knauf Safeboard X-Ray Shielding Boards

ConstructionKnauf Safeboard X-Ray Shield Partitions are metal stud partitions consisting of a metal stud framework with cladding made of Knauf Safeboard X-Ray Shielding Boards and an optional top layer made of Diamant boards on both sides. The stud construction is connected all around to the flanking constructional components.Insulation material for sound and thermal insulation or fire protection as well as sanitary or electric built-ins can be installed into the metal frame construction cavity while ensuring continuous shielding (backings/covering boxes of penetrations or built-ins). Movement joints of the main structure of the X-Ray Shield Partition have to be included in the construction of the partitions. Movement joints are to be installed every 15 m on continuous partitions.

The installation of X-ray shielding doors in Knauf X-Ray Shielding Partitions is possible. Follow instructions of the door supplier for the construction of the door opening.

■ Fasten perimeter runners using suitable anchors on the flanking constructional components. Fasteners for solid flanking constructional components: Knauf Drehstiftdübel nailable plugs or Knauf Deckennagel Ceiling Steel Dowels / non solid constructional components: Special anchors suitable for the building

materials. Refer to the table on page 15 for the required spacings.

■ Place the CW studs into the UW runners arranged along the length at the required axial spacing and align them.

Deflection headsThe type of ceiling connection is dependent on the displacement that is to be expected after the installation of the partitions for the flanking constructional components. If a deflection of the ceiling ≥ 10 mm can be expected, install deflection heads.Deflection heads must be implemented so that they can be set to the expected deflection between the partition and flanking constructional components. Requirements for the sound insulation and/or fire protection must be taken into consideration during implementation.

Work sequence in the connection areasThe X-ray shielding layer must also be applied continuously in the area connecting to flanking components.

■ Complete a continuous X-ray shielding layer made of Safeboard.

X-Ray shielding furringWith Knauf Safeboard X-Ray Shielding Boards

With Knauf X-Ray Shield Furrings, existing walls can be upgraded for X-ray shielding. These measures are particularly cost-effective to apply when combined with a Knauf Safeboard cladding.

Knauf X-Ray Shielding Furrings with metal stud framework are equipped with a cladding made of Knauf Safeboard X-Ray Shielding Boards according to the required lead equivalence and a top layer made of Diamant boards.

Furring directly anchored or stand-aloneFurrings consist of a metal substructure and a one-sided single, double or triple layer screwed on cladding. The substructure is connected to the adjacent structure along the entire perimeter and in case of system K151.de additionally anchored to the solid wall. Insulation material for sound and thermal

insulation as well as sanitary or electric built-ins can be installed into the metal frame construction while ensuring continuous shielding. Movement joints of the main structure should be integrated into the construction of the furrings. Movement joints are to be installed every 15 m on continuous furrings.



■ Sound insulation: Knauf sound insulation proof SWK 11 108

■ Structural: abP P-1403/355/12-MPA BS or Knauf dimensioning based on abP P-1403/355/12-MPA BS

► Good to know Diamant as a cover layer

■ In order to protect the X-ray shielding layers made of Knauf Safeboard from damage caused by mechanical influences, it is recommended that you apply the X-ray shielding furring with a cover layer made of 12.5 mm Diamant.

X-Ray Shield CeilingsWith Knauf Safeboard X-Ray Shielding Boards

Knauf X-Ray Shield ceilings as suspended ceilings provide X-ray shielding for ceilings. Knauf X-Ray Shield Ceilings with metal substructure as suspended ceilings are anchored on the basic ceiling with Universal Brackets or Nonius suspenders and are equipped with a single, double or triple layer of Safeboard cladding acc. to the required lead equivalence. Insulation layers for fire protection or sound insulation and thermal insulation as well as installations that are anchored on the basic wall can be installed in the ceiling plenum. Movement joints have to be transferred into the construction of the suspended board ceilings. Control joints are required in the case of ceiling areas exceeding approx. 15 m in length and for narrow ceiling spaces caused by a break of a wall.

Suspenders Load bearing capacity 0.40 kN ■ Universal Brackets / Damping Universal Bracket for CD 60/27

■ Adjustable Universal Brackets / Damping Universal Bracket for CD 60/27

■ Nonius-Bügel (Stirrup) for CD 60/27 + No-nius top

■ Nonius Hanger Bottom + Nonius Top If the ceiling load exceeds ≥ 0.5 kN/m² and/or in case of fire protection require-ments from above, screw connect Nonius Hanger Bottom to the CD Channels with Metal Screws LN 3.5x11 mm. Knauf recommendation: Screw fasten in case of total ceiling load ≥ 0.4 kN/m² to increase the installation safety.

Extension of the fire resistance Certificate of Usability

■ Due to the laminated lead sheets Prior consultation in acc. to page 2 is recom-mended.

Knauf X-Ray Shielding Partitions with metal studs are clad with Knauf X-Ray Shielding Board lead sheet (Fire-Resistant Board with sheet lead lining on the rear) and cladding, if necessary, of Knauf Bauplatte (GKB) or Feuerschutzplatte Knauf Piano (GKF). The stud construction is connected all around to the flanking constructional components.Insulation materials and electrical built-ins can be installed in the wall cavity. The sheet metal lining does not impair the fire resistance of the partitions. Movement joints have to be transferred into the construction of the X-Ray shield partitions and furrings. Movement joints are to be installed every 15 m on continuous partitions.

X-Ray shielding partitionsWith lead sheet laminated gypsum boards

The installation of X-ray shielding doors in Knauf X-Ray Shielding Partitions is possible. Follow instructions of the door supplier for the construction of the door opening.

► Good to know ■ Larger sheet metal gauge possible on

request. Additional measures may be required.

■ Combined cladding with Knauf Safeboard + X-Ray Shielding Board lead sheet possible.

Dimensioning of the grid

1) Determination of weight of the X-Ray Shield ceilingRead off suspended ceiling weight acc. to the weight per unit area of lead sheet in kg/m².

2) Consideration of additional loadsMaximum additional load from insulation layers (max. 0.05 kN/m² = 5 kg/m²) increases the total area weight of the suspended ceiling/ceiling lining and must be considered with the load class ratings.

3) Dimensioning of the gridThe required substructure spacings are stated depending on the load class / load per area weight in acc. to the table on page 48.

Surface quality ■ Fill and finish the gypsum boards for the specified quality standard Q1 to Q4.

Filling of gypsum board joints ■ For multi-layer cladding, fill the lower layers with filler to quality level Q1, fill the joints of the visible layer as required to Q1 - Q4.

■ Fill in visible screw heads. ■ Lightly sand visible surface after drying of filling compound, if necessary

Filling of connection joints ■ Fully fill joints of wall connections to floor with filler as well (all board layers) with filling compound (use Safeboard filler for Safeboard layers).

■ Apply Trenn-Fix or Fugendeckstreifen Kurt joint tape when filling joints to adjacent drywall

constructions, taking into consideration the conditions and requirements for crack safety.

■ Apply Trenn-Fix when filling joints to adjacent solid construction components.

■ Observe Code of Practice no. 3 “Gipsplattenkonstruktionen - Fugen und Anschlüsse” of the BVG (IGG).

Filling compounds ■ Safeboard-Spachtel filler: Hand filling of Safeboard X-Ray Shielding Board without joint tape

■ Uniflott: Hand filling without joint tape strips in the long joint edges

■ Fugenfüller Leicht: Hand filling with Knauf Joint Tape Kurt

Suitable finish filling compounds ■ Q2, application by hand: Readygips ■ Q3/Q4, application by hand: Readygips, Knauf

Jointing

ApplicationUniflott / Uniflott impregnated

■ At least 2 steps, depending on the required surface quality. Fill the joints, remove the excess material (strings) after approx. 50 minutes. Create a smooth and levelled transition to the board surface in the second step with a trowel or wide spatula.

Fugenfüller Leicht/Joint filler Super ■ Fill joints, apply Knauf Joint Tape Kurt and embed with the trowel. Second work step after drying as with Uniflott.

Knauf Safeboard-Spachtel filler ■ Application analogue to Uniflott, with visible cladding layers and surface quality level Q2 with second stage using Knauf Uniflott. See also Product Data Sheet Safeboard filler K467S.de.

Do not use hardening material. Remove slight bumps directly after setting. Clean the tools with water after use. Sand with Knauf Hand Rasp / Grinder with Shaft and Rasp Mesh after drying.

Application temperature / climate ■ Filling and covering of joints should only take place when no more longitudinal changes can be expected, e.g. expansion or contraction due to humidity or temperature changes.

■ Joints may only be filled if the minimum room temperature is not below about +10 °C.

■ In case of mastic asphalt screed, cementitious screed and self-levelling screed, fill in board joints after screed has been applied.

■ Observe code of practice no. 1 “Baustellenbedingungen” of the BVG (IGG).

1st stage, Safeboard filler 2nd stage, e.g. Uniflott

Safeboard joint application ■ Bevel the front edges and cut edges, e.g. with Knauf Kantenhobel beveller.

■ Fill all joints (board joints and connections fully, i.e. uniformly and over the entire cladding thickness of all Safeboard layers with Safeboard-Spachtel filler.

■ With visible cladding layers for manufacture of surface quality Q2, create a level transition to the board surface in the second step with Knauf Uniflott.

Safety note ■ When processing Knauf Safeboard, particularly when sanding and sawing (e.g. using a keyhole saw), as well as when sprinkling the filler powder, a dust mask (P2) must be worn.

► Good to knowFilling the joints of covered cladding layers with multi-layer cladding is necessary to guarantee X-Ray shielding, technical fire protection and sound insulation properties as well as the structural properties! With multi-layer cladding, filling of the lower cladding layers without further joint filling is sufficient.
