Prompt-Gamma Neutron Activation
|Volunteer undergoing test for Total Body Nitrogen|
The CNRC is home to one of six Prompt Gamma Activation Analysis machines in the world. This machine is capable of measuring nitrogen in the body. Nitrogen is a direct indicator of total body protein. A high nitrogen reading indicates healthy tissue. When this measurement is combined with measurements from the Total Body Potassium Counter (40K), scientists can determine total organ and muscle mass.
