Tube and Rod Sources for Well Crystals

radiation tube sources for well counterWe offer a selection of exempt quantity gamma sources encapsulated in standard size test tubes or rods for use with well type radiation detectors. These sources are uncalibrated and of nominal activity. The isotope is deposited as a point source in the bottom of the tube and is then sealed with epoxy.





radionuclide rod source by SpectechTwo tube sizes are stocked as standard, 13x100mm and 12x75mm with other sizes available on special order. Rods are available as 5"x0.375" and 5"x0.5".
