Lead boards for X-ray protection
Laminated lead on gypsym/pasterboard or wooden based board is the common product.
Lead on plasterboard is a usual alternative which also gives some fire-resistance. This solution comes with the CE-marking.
If a more load-bearing construction is needed in the wall, lead is laminated to OSB or plywood and placed against the joists at the bottom of the wall construction. It is common for plasterboard to be placed on the outside to give the surface you want.
The assembly is made so that a joint strip with lead is placed on the stud and places the board with lead so that lead meets lead overlapping. In this way, the solution becomes completely radiation-protected. In the corners, wider strips should be placed so that the lead overlaps sufficiently enough.

Lead-free radiation protection boards
Strålskydd RSE AB can deliver radiation protection boards without lead.
Lead free boards contain the shielding subject barium sulphate in powder form which is integrated in the gypsum.
The boards are handled as ordinary plasterboard during assembly and are sound-insulating and fire-resistant as well as other plaster boards. In order to achieve higher lead protection, several layers are often needed.
The boards usually have the dimensions 625 * 2500 * 12.5 mm and a weight of 17 kg / m2. Each layer of boards needs to be filled with special putty containing barium sulphate to handle the radiation.
Make a request
It is the machine’s radiation or the radiant preparation that determines how much protection is needed, hear with the machine supplier or the radiation physicist what is required for the room you are protecting.
For price and environmental reasons, you want to use as little protection as possible.
For dentists it is common with 0.5 – 1.0 mm lead (lead equivalence) on the walls up to a height of 2100 mm, while in hospital environment it is common with 2 mm lead up to 2100 or 2500 mm on the wall. The machine decides!
For veterinarians, both variants may occur depending on the machine and the size of the animals.
There are also machines that require more protection than this, and sometimes special solutions are needed to get it tight.
If you require lead from 0.5 mm you will need splice strips between the boards to make it tight. The joints in the corners of the rooms need to be wider. Notify how many corners you need lead protection to.
