Nuclear threat detection remains a vital global security concern, particularly in environments requiring real-time, non-contact monitoring. This study presents a remote detection system that combines laser-induced breakdown spectroscopy (LIBS), machine learning, and wireless signal optimization to detect uranium and plutonium from distances of 30 to 70 meters. The DRUP-LIBS system utilizes both multi- and single-wavelength laser pulses to generate actinide-specific plasma emissions, which are analyzed using artificial intelligence with 100% classification accuracy. Wireless modules equipped with directional antennas maintained signal quality over long distances. Plasma temperature and electron density were measured using Boltzmann plots and Stark broadening, confirming plasma consistency. Results show that the system reliably distinguishes between uranium and plutonium, with plutonium exhibiting stronger emissions and higher electron density. These findings support DRUP-LIBS as a secure, non-intrusive tool for real-time radioactive threat detection in open environments.
