What could walls in hospitals and other healthcare facilities contain?

The presence of lead-lined gypsum in walls of hospitals and healthcare facilities primarily serves to protect both patients and staff from radiation exposure. In areas where X-rays or other imaging services are performed, walls are typically constructed with lead-lined materials to provide a barrier that absorbs radiation, ensuring safety standards are met.

Lead-lined gypsum board combines the function of standard gypsum wallboard, which provides fire resistance and structural support, with an additional layer of protection against radiation. This is essential in areas such as radiology departments, surgical suites, or any facility where radiation-emitting equipment is used.

The other options do not provide the necessary safety or functionality required in such environments. Mirror siding, while aesthetically pleasing, does not offer structural benefits or radiation shielding. Organic insulation is not typically used in healthcare settings due to potential microbial growth and health concerns. Textile coverings, although they may provide some sound absorption or aesthetic benefits, are not designed for the rigorous safety and structural requirements necessary in a healthcare environment.
