Automated radioisotope identification using fuzzy logic and portable CZT detectors

Automated in-field radioisotope identification presents many challenges, including difficult choices in detector technology, the need for high-reliability low-power electronics, and imprecise analysis methods. To meet these challenges, we have developed ruggedized large-volume CdZnTe (CZT) detectors that are coupled to state-of-the-art low-power electronics to perform radioisotope identification with fuzzy logic in real time. The analysis is presented in a simple straightforward manner that enables first responders, customs agents, or other nonexperts to detect, locate, and identify sources of radiation
