It is often the belief that electron accelerators are clean machines, producing little or no measurable removable contamination. However, at the Thomas Jefferson National Accelerator Facility (Jefferson Lab), a 200 {micro}A continuous wave, 4 GeV electron accelerator, there are several types of contamination that may be found: external contamination of beamline components near high beam loss points, radionuclides produced from the spallation of oxygen in air, and internal contamination of water systems used to cool beamline components. The last two categories, however, are fairly well understood and are not discussed herein. The Jefferson Lab Radiation Control Group has developed a comprehensive set of contamination control practices to identify and control personnel exposure to these radionuclides.
