Preliminary Studies of Perovskite-Loaded Plastic Scintillator Prototypes for Radioactive Strontium Detection

Functional plastic scintillators have attracted much attention for their usefulness in on-site monitoring and detection environments. In this study, we elucidated a highly reliable functional scintillator of radioactive strontium, which means potent perovskite-loaded polymeric scintillation material based on epoxy 2,5-diphenyloxazole (PPO). Moreover, Monte Carlo N-Particle (MCNP) simulation was performed to optimize the thickness efficient strontium detection. A 2 mm found be optimum beta-ray newly developed with 430 nm emission from perovskite loading could trigger enhancement employing potential indication energy transfer into photomultiplier (PMT) detector. Furthermore, response emitter 90Sr compared commercial BC-400 by exhibiting efficiency spectrum fabricated scintillator. We believe that suggested employed as radiation detector wide range applications including decommissioning sites nuclear facilities, security monitoring, nonproliferation, safeguards.
