Collimators are one of the most effective means available for reducing the radiation levels on a job site. Collimators also increase the quality of radiography shots by reducing the amount of scatter radiation that reaches the film. Collimators help reduce your restricted area and aid in obtaining As Low As Reasonably Achievable (ALARA) radiation levels. This translates into safer operating conditions for radiographers.

Because tungsten is a more effective shielding material than lead and is an easy-to-handle, non-licensed material, it makes a very effective shielding material. Another feature of the tungsten collimator is that it does not spark, so it is ideal for plant operations. In addition to the standard collimators listed below, SPEC can build a collimator to your specifications.

SIDE PORT COLLIMATORS, 90 DEGREE MINIMUM BEAM
Attaches to the end of the source tube and emits a 90 degree beam angle from an end port and is shielded in the rear and sides. Used to direct the beam totally away from the radiographer.
