Siniat do not have any specific solutions for rooms that generate X-Rays. When specifying partitions for such areas, the core wall will be designed to meet the fire resistance, acoustic, duty and height criteria. 

Siniat boards are not inherently capable of stopping X-Rays. Third party companies take plasterboard from various manufacturers and bond specifications of lead to the back for installers to use. They typically have a suite of details to ensure the wall and junctions are fully capable to block X-Rays. This is applied to the core wall as an additional layer as specified to meet the necessary requirement.
