Accurate results with natural background rejection

Naturally occurring radiation exists in varying levels from the earth and atmosphere as well as non-threatening artificial radiation exists from medical treatments or as sources in gauging instruments, which can obscure and confuse targeted detection efforts. 


Natural Background Rejection (NBR) is a technology used to eliminate fluctuating natural background levels without sacrificing sensitivity. This proprietary and patented technology quickly differentiates between natural and artificial radiation and strips it from the measurement, delivering you an instant and more accurate result of artificial radiation levels. Operators using instruments without NBR often set their alarm thresholds higher to eliminate the nuisances of false alarms or ignore alarms due to their frequency potentially missing out on hidden or shielded sources. Using an instrument with NBR allows you to keep your alarm threshold extremely low without the need to worry about false alarms from non-threatening sources.  When a RadEye the alarm goes off, you know it is time to take actionact.
