The researcher has been monitored since February 2012 and has frequently used F-18 in similar studies with no problems. Use of PET isotopes in the lab has been halted pending an investigation by the licensee. The Maryland Radiological Health Program will schedule a reactive investigation. The result of the whole-body radiation badge readings (monitoring period Oct 1 - Dec 31, 2017) was: Deep Dose: 12,818 milliRem
