Some practical advantages of sealed tube 14 MeV neutron generators for total body in vivo activation analysis

Summarizes the practical advantages of using for this purpose, two sealed tube 14 MeV neutron generators with a scanning geometry in conjunction with a shadow-shield whole body counter. The requirements of neutron sources for TBIVAA include: uniformity of fast and thermal neutron fluence through the body, the simultaneous measurement of as many body elements as possible, especially Ca, P, N, Na and Cl; an acceptable neutron dose; reproducibility; an irradiation procedure causing as little inconvenience and trauma as possible to the patient; and acceptable costs.
