Radiological Training for Accelerator Facilities
Liquids subject to activation include:
Cooling water: Cooling water is used for cooling beamline components (activation
products such as tritium, H-3, and wear products from piping).
Oil in vacuum pumps of beam line components.
Cryogenic fluids: Liquid helium and nitrogen are used frequently to cool
Facility Specific (Insert facility-specific information concerning radioactivation.)
Materials and activities that could create contamination concerns include:
Surface coating: Surface coating, such as paint or oxidation and/or rust, may present
a contamination problem. Such coatings may be easily removable and may be
present in areas not commonly accessed, such as beam dump vaults.
Compounds: Compounds, such as grease, sealants, gaskets, and anti-seize coatings,
may be activated depending on their composition. During maintenance, these
compounds should be chosen carefully to minimize the production of contamination
if possible. These materials may not be accessible until after components are
disassembled; therefore, the need for carefully planned maintenance activities
involving such compounds should be highlighted.
