So, what's the exactly components substance of the plastic scintillators we are looking for ? which...(and after all this time researching...) is in fact the radioactive source of the x ray machines...produced by nuclear reactors.
Ytterbium Fluoride (YbF3, 99 %, 40-80 nm)
Size: 40-80 nm Purity: 99% Nanoparticles: Ytterbium Fluoride Morphology: nearly spherical Type: GNM ID: #5670YD Properties: Ytterbium Fluoride Nanoparticles: #5670YD
Good morning! welcome back to war! What I have here is the specification of a plastic scintillator named Bicron BC-408, as you see on the technical photo, the source is cesium 137, cobalt 60 and sodium 22 , all high radioactive. If you go on searching, and there's lots for sale at eBay, the sellers will say to you that it will only work if mounted on a PMT , that creates a sort of confusion, PMT photomultiplier detector is based on radiation sources like NA(TI) (encapsulated sodium on lead protecting thallium ) ; anyway, one thing doesn't imply on the other...both this Bicron -408 and the PMT have radioactive sources. The blue colour emission, comes from anthracene , (a component of 20% of carbon at space), specifications like, emission of electrons on the infinite number 10(23) (this is the calculation of infinitive on physics) , and the emission of photons, surely defines this material (plastic) as radioactive.
