Abstract:
Dose rate measurements were performed in 0.5, 1 and 2 m distance from the surface of the bodies of 16 patients within the first 4 h after they had received 600 +/- 30 MBq of 99mTc-DPD. The various individual time to dose rate courses are discussed. The radiation dose rates around the patients were determined and the possible radiation exposure of other patients, attendants, and nurses in the surroundings of the "radiating" patients were estimated. The doses were far below the limits set by radiation protection regulations.
