Source Holder

The source holder is constructed from stainless steel or low carbon steel with a 
polyester powder coating and  performs the following:

•

Houses all radiation-emitting source capsules.

•

Protects the radioactive source.

•

Provides a means for shielding and locking out the radiation beam.

•

Shields all areas in which radiation is not intended.
