Obtaining a Dosimeter at SLAC
The law requires radiation dose measurements for potentially exposed
workers. Although radiation levels are low at most SLAC locations, we
measure personnel radiation doses for certain personnel to ensure that dose
levels are "As Low As Reasonably Achievable" (ALARA) and keep records which
are required by the Department of Energy. Information about radiological
areas and who needs to be trained and wear dosimeters is in the
Radiological Work and Area Entry Requirements [pdf]; a basic chart is on
In general, you will need to have training and wear a
dosimeter if your work takes you into Radiologically Controlled
Areas (RCA), Radioactive Material Areas (RMA), or Radiation
Areas (RA). Specific locations and requirements are
Classification of Radiological Areas at SLAC [pdf]. If you are unsure if you need a
dosimeter, please consult with your manager.
The classes are online web-based training. See the Training website for more information on
