and..another photonics..

EXCELLENT USED CONDITION, TEST OK ~. used,so have minor scratch while handling. | eBay!

and here we have, both thulium and Ytterbium fiber

End of fibre cable is covered to avoid inadvertent exposure to the invisible radiation. Special Warning: This unit is an industrial Laser with maximum output of 15W average, 10kW peak pulse. (duration 120nS), wave length 1700-2200nm (invisible). | eBay!

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.

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.
