Detect even the most minute amounts of radiation within seconds and immediately determine whether it is natural or artificial. The Thermo Scientific™ FH 40 G NBR Survey Meter uses patented advanced Natural Background Rejection (NBR) technology to distinguish between naturally occurring radioactive material (NORM) and radiation from manmade sources. From first responders dealing with radiation emergencies to environmental monitoring and remediation personnel, this high-efficiency detector quiclky locates contamination or hidden radiation sources and accurately determines the dose rate.
