PM capsule type
|
Alpha Particle Standards—Type PM The PM source is mounted in a plastic holder from which it can be separated for installation in a counting chamber or device. The holder is 1” diameter x 0.125” high (25.4 mm x 3.18 mm). The removable active foil is 0.438” (11.1 mm) in diameter with the active diameter 0.197” (5.0 mm). The foils are platinum or platinum clad nickel between 0.005” and 0.010” (0.127 mm and 0.254 mm) thick. All alpha standards are offered as spectral grade sources up to the activity and active diameters listed unless otherwise noted. All electroplated alpha standards are manufactured to an accuracy of +/-30% of the nominal activity. |
