Title	Whole Body Dosimetry Indicates Exposure of Over 11 Rem
Event Description	On December 29, 2020, Yale University received notification from their dosimetry vendor that one of their employee's badge indicated a whole body dose of 11,843 mRem for the October 2020 wear period. The employee works in the radiopharmaceutical area of the University. When the employee was interviewed, they admitted that they could not locate their whole body badge when swapping out the October badges for the November badges. The employee found their badge on November 17, 2020 in the fume hood where they believed it fell off their lab coat when cleaning the fume hood for maintenance. The employee's ring badges for the October wear period was 73 mR (left) and 63 mR (right). November ring badge readings were about the same with November whole body dose of zero.
