Detection of Radioactive Gas with Scintillating MOFs

Homogenous radioactive gas contamination constitutes the hardest challenge for radioprotection due to its elusive nature. Most common are 85Kr, 222Rn, and tritiated (3H) vapors. Each of them has different challenges, often leading specialized single-gas detectors. The state-of-the-art detection either produces chemical-radiological waste, is hard implement online, or requires large volume. A new paradigm presented that can perform online on any fit in hand. This study use photoluminescent metal organic frameworks (MOFs) as both porous sponges scintillators. response several zinc based MOF studied, using a unique test bench. These tests showed MOFs able concentrate detect successfully 85Kr. investigation completed with calibration activities. also reports measurement half-life. Finally, successful dihydrogen, commonly known be radionuclide low energy penetration range. paper shows scintillating powerful solid-state approach practical solution measurements.
