The development of the k_0 method in Peru: Past, present and future perspectives

摘要

The k_0 method was implemented at the Peruvian Institute of Nuclear Energy (IPEN), by 1993. Since the middle of 1994, almost all INAA work at IPEN is performed by the k_0 method. The establishment, applications, development and future of the method in Peru are presented from a retrospective and prospective view. Attention is paid to difficult aspects, e.g. counting efficiency, characterization of irradiation facility; non-ideal behaviour of the epithermal neutron spectrum and consistency of nuclear input data.
