what are survey meters used to measure? radiation exposure rates what type of survey meter is used for surveys to detect contamination? Geiger-Muller (GM) counter The NRC requires that a nuc med facility have a survey meter capable of detecting exposure rates between what range? and what instrument accomplishes this? 0.1 mRem/hr and 100 mRem/hr GM what two things can be fitted at the end of a GM counter end window probe and pancake probe what doe a pancake probe do? allows tech t...

18F-FDG is rarely used to image tumors in the kidney, prostate, or bladder because: FDG is actively excreted in the urine, obscuring tumor uptake in these organs A patient who is maintained on a ventilator is transported to the nuclear medicine department. In the transfer process, it is necessary for the nuclear medicine technologist to compress the Ambu-bag being used to sustain the patient's breathing during transport. The rate for compression of the bag should be approximately: Once every...
