X-ray and CT rooms

Where to start

Rooms housing equipment that emits radiation must be shielded so that it does not pass to the outside. The required thickness of lead is calculated by a radiologist in the shielding design and given as a Pb equivalent in millimetres.

With that equivalent in hand we select the material: thin layers are done with foil, thicker ones with sheet, and where speed of construction matters, with lead-lined plasterboard.

What goes where

1. Walls - lead foil or self-adhesive foil behind plasterboard, or ready-made lead-lined boards
2. Doors - lead sheet bonded to the leaf, finished with paint in any RAL colour
3. Viewing windows - leaded glass with an equivalent matched to the rest of the shield
4. Service penetrations - cut-outs in the sheet, sealed with lead wool
5. Joints and fixings - self-adhesive lead tapes and caps for screws

Why this is not ordinary building work

A shield only works if it is continuous. Every gap at a board joint, every uncovered screw and every service penetration is a place where radiation passes through. That is why we supply not only the material but also the accessories for the joints - and carry out the installation if you wish.
