Radiological Training for Accelerator Facilities

Student's Guide

Lesson Plan

Notes

Compounds: such as grease, sealants, gaskets, and

anti-seize coatings may be activated depending on

their composition. Prior to 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.

Impurities: Impurities in cooling water systems can be

a source of contamination. This source may be found

in a filter/resin media system.

Activities: (Facility-Specific) routine work areas

where contamination control must be considered:

Machining of radioactive materials.

Cooling water filters.

Accessing beamline.

Maintenance.

Target removal.

Etc.

Ancillary Sources

Accelerators employ devices to impart energy to particles or redirect

them during the acceleration process. These devices may emit ionizing

radiation while they are operating.
