Development and Medical Applications of a Simple Facility for Partial Body in Vivo Neutron Activation Analysis Using Californium-252 Sources. Final Report for the Period 1 September 1976 - 30 August 1977

摘要

A simple and cheap facility for partial body neutron activation analysis has been designed, based on the use of two 100 mu g exp 252 Cf neutron sources. The results reported show that calcium can be measured in parts of the body such as the tibia with a precision as good as +- 1.6 % for a radiation dose of 2 rem. The uniformity of the thermal neutron flux density is better than +- 3 % over 10 cm. Some applications of this irradiation facility for studies of trace elements, in particular cadmium in liver and aluminium in liver or brain, have also been explored. However, the sensitivity attainable is not yet sufficient for the study of normal levels, but could be of interest in toxicological investigations. (Atomindex citation 11:508431)
