Guardian™ Lab Systems are trusted worldwide to detect and locate sources, incorporating state-of-the-art passive scanning technology to detect changes in gamma radiation levels. The Guardian Lab System was initially designed to detect radionuclides in material sample coupons as part of the quality control process for the production of steel and aluminum. Trusted in the metals industry for over 15 years, the Guardian Lab System is now used to test food and water samples for radionuclides and to perform NORM analysis for geological samples.
