Radiation Detection Measurement

The rise in scrap metal recycling means more scrap of unknown quality and origin. Radioactively contaminated scrap threatens both the workers who handle it and consumers of products made with recycled scrap metal. The Thermo Scientific™ ASM™ IV Series Automatic Scrap Monitoring System monitors vehicles entering the scrap yard, or processes within the facility, and provides accurate, reliable detection of radiation sources commonly found in scrap metal. With high performance and a low false alarm rate, the system rejects radioactive materials before they can harm people or the environment.
