Standard Californium-252 Sources: Model 100 Series
The Model 100 series of Cf-252 neutron sources are doubly-encapsulated sources which employ a Model 10 series source as the primary encapsulation. Model 100 series sources have an outside diameter of 0.370/0.371 inches and are available in two lengths, both of which are available with or without a 10-32 threaded stud on one end. The longer length version with the stud is equivalent to the Savannah River SR-CF-100 series capsules. Outer capsule material may be either type 304L stainless steel or Zircalloy-2. Closure is by TIG welding.
- Double encapsulated, employing a Model 10 series source as the primary encapsulation.
- The outer capsule material is either 304L stainless steel or Zircaloy-2.
- All sources NIST traceable
Thirty-two version of the standard length source available in various combinations of inner and outer capsule materials, orientations and with or without the threaded stud. Upon request, custom configurations are also available. All Model 100 series are certified by the USDOT as Special Form, and all have been approved for licensing purposes by the USNRC for general uses.
