I foudn a box of photomultiplier tubes and I opened up one of the tube boxes and it is a Harshaw scintillation detector tube. However at the top was an aluminum "pot" about 1.75" wide with a piece of glass over the top. The inside has some sort of weighty matter that is almost exactly this color green:

I know it is a radioactive source of some type because the manufacturer is Isotopes, inc, bearing type code S64. I thought the type may refer to the periodic symbol and isotope, but S is for sulphur and it doesn't have a 64-nucleide isotope, plus the isotopes have short halflives.
I found some datasheets that were for another tube that said the radioactive source was Iron-55. However, what little I can find on it says that the color isn't different than normal iron. I know that uranium is used for a green pigment, but it isn't THAT heavy. I also don't have a black light to see if it glows like uranium does. (that, and it's cloudy outside)
Keep in mind that this thing is over 40 years old, so if its got a short half-life, I'm keeping it.
