Rapid HPGe well detector gamma bioassay of (137)Cs, (60)Co, and (192)Ir method.

CDC designed a rapid HPGe Bioassay Method for (137)Cs, (60)Co, and (192)Ir that is suitable for a public health response to a radiological incident where people may ingest or inhale radionuclides. The method uses a short count time, small sample volume, and a large volume detector and well size. It measures a patient's urine sample collected post-incident. The levels of concern are directly related to the Clinical Decision Guide levels recommended in the National Council of Radiation Protection 161.
