The Analytical Sensitivity Research Of A Photoneutron Based Drugs Detection System

Photoneutron based thermal neutron analysis (TNA) drugs detection system is a promising technology for drug control because of its capability on elemental concentration analysis. In this work, by simulating the signal emitted by drugs with this system and predicting the time required to control the false rates, the minimum detection time to detect smuggled drugs is evaluated. The result reveals that <0.2 s inspection time is adequate to realize a <5% false positive rate and a <5% false negative rate for the detection of smuggled drugs.
