Abstract
The increasing intensity of neutron sources, advantageous for increasing the yield of information obtained and for making possible investigations in near-background conditions, entails also taking account of reaction processes which previously could be neglected. These include the formation of recoil nuclei and the dispersion of the irradiated material. Neglecting such effects at high neutron intensities has been found to distort the actual reaction picture and serve as a source of error. In this paper the authors review and seek to optimize conditions for neutron activation analysis under increasing neutron flux scenarios by investigating the contribution of target geometry and recoil production of various metals and radionuclides to the accuracy of the analysis.
