Improvements to the in vivo measurement of cadmium in the kidney by neutron activation analysis.
The McMaster University in vivo cadmium measurement system has been upgraded. Two large surface area hyperpure germanium planar detectors (51 mm diameter x 21 mm depth) are now employed for the detection of the 559 keV gamma-ray signal from cadmium. Phantom studies indicate that the new detectors have significantly improved the system. The detection limit in kidney phantoms has been reduced from 8.9 to 3.8 mg for the same dose and measurement time.
