Cherenkov counting

Microfluidic synthesis of radiotracers: recent developments and commercialization prospects

“…Cherenkov radiation occurs when a particle moves in a medium faster than the phase velocity of light in that medium. 130 When 18 F decays and releases a positron, the particle can briefly achieve velocities high enough to create Cherenkov radiation which can propagate and produce a spectrum from the near-UV to visible spectrum. 131 The radiation has been used to image radiation through PDMS, 128,132 glass, 96,105,[114][115][116] and a plastic scintillator.…”
