Light-tight Beta Scintillator System Twin

The Swisstrace beta scintillator systems are built to be used in daylight. This is possible because the beta scintillators are specially coated. Another big advantage of the coating is that interference with Cherenkov radiation is also eliminated. Furthermore, the photomultiplier tubes inside the system are lead-shielded. No additional lead is therefore required to shield the system during the experiments. Moreover, the use of state-of-the-art PMTs reduces dark counts to neglectable levels without cooling. This device allows for on-line monitoring of tissue tracer concentrations in animals with high temporal and spatial resolution.
