  • Pick-up new dosimetry badges ONLY after attending the radiation safety training and completing the RASCAL post-test online.
  • Return all dosimetry badges on a timely basis. In order to properly monitor occupational exposure as well as prevent late charges, badges must be returned within 22 calendar days after the end of the wear period. Note: Wear end dates are printed on all badges below your name.
