Personal dosimetry in the PET Centre Prague.
This work is focused on radiation protection in the PET Centre Prague. The personal year dose equivalents of physicians, technologists and lab-technologists in the period 1997-2000 are presented. Dose equivalents are listed for each group as collective, mean and maximum dose equivalents and number of people in the evaluated group. There is an increase in the dose equivalents in 1999 when the PET scanner was installed. Later on, when personnel was trained and better local shielding was used, the increase is not much higher even though the number of patients investigated per day doubled. The radiation field measurements showed that the radiation dose equivalent rate outside the controlled area is on the background level of about 0.17-0.18 mSv/hour.
