The world has become a much noisier place, and we’re surrounded by distractions. The average city-dweller is pretty good at filtering out unimportant sounds over the course of a typical day, but most of us need peace and quiet as we rest and as we work.

The technicians who perform the procedures are around radiation every day, and it’s important that they’re shielded from harmful gamma rays when they do their jobs.
