GIB X-Block® is a lead free plasterboard system used as an effective radiation barrier. Barium Sulphate in the GIB X-Block plasterboard and compound provide protection against X-rays.

X-ray shielding requirements are usually specified as a thickness of lead. The lead equivalence of GIB X-Block systems depend on the energy level of the radiation. Tables 1 and 2 state the lead equivalence of GIB X-Block systems at various X-ray energy levels. Always seek advice from a Health Physicist to ensure that the requirements for radiation shielding are met.

This section contains radiation test results, shielding requirements, systems, installation instructions and construction details for GIB X-Block systems.
