VEGASOURCE 82 • Source holder

In this case, the source holder must be dismounted. The radiation
safety officer has to prescribe dismounting.
Direct the exit channel towards a thick wall (e.g. of steel or lead) or
mount a blind flange or blind plate in front of the exit channel.
Persons may only stand behind the source holder. Never stay in
front of the radiation exit channel (flange or mounting surface of
VEGASOURCE 82).
The transport lug on the housing facilitates safe handling.
In this case, the source must be kept secure in another place or an
additional shielding must be provided.
The radiation source may only be transported with tongs or a gripper
as well shielded as possible and must be kept as far away from the
body as possible.
The time required for transport should be estimated and optimized in
advance through tests and training.
