Metal Organic Frameworks: A new class of scintillators for radioactive gas detection

Résumé

The detection of radioactive gases, 85Kr, 222Rn, and 3H, represents a significant challenge in nuclear detection due to their inherent volatile nature. No convenient one-size-fits-all detection system exists for the online measurement of these three gases. We hence propose a new class of scintillators with high surface areas, which optimizes the interaction between the radioactive gas and the scintillator. Metal Organic Frameworks (MOF) are ideal porous candidates for this application. They are the material with the highest known surface areas, up to 8000 m2.g-1, and have been studied for their fluorescent and scintillating properties. To the best of our knowledge, the use of MOFs as scintillating sponges to detect radioactive gases has only been theorized. We were able to experimentally demonstrate, using advanced coincidence techniques (TDCR) and a homemade metrological test bench, that MOFs are indeed scintillating in the presence of all three targeted gases.
