Visualization of tritium radioactivity using a melt-on scintillator was studied in order to reduce radioactive waste. The melt-on scintillator immersed glass filter with various tritium radioactivities were measured with an imaging analyzer, a plate reader and a CCD imager. Tritium radioactivities were detected in a plate reader and a CCD imager. 8.6 kBq of tritium was visualized using a CCD imager.
Using melt-on scintillator, 3H sample can be visualized directly, therefore, the image of them has a potential to reduce radioactive waste.
