The Nucsafe® Shield area monitor uses state-of-the-art passive scanning technology to detect changes in radiation levels emitted by gamma radiation. The Nucsafe Shield area monitor is designed for remote operation, monitoring key locations in steel mills, such as gauge houses and laboratories. It utilizes spectroscopic technology to reliably identify nuclides present in a designated area.
