To establish the facility specifications, the neutron flux values along the irradiator axis were determined experimentally and calculated by Monte Carlo method. The irradiator presents the advantage of supplying a stable neutron flux for a long period, eliminating the need to use standard material (comparative method), so that the process becomes agile, practical and economical.412-414closedAccessirradiation devicesneutron fluxneutron sourcesneutron activation analysismonte carlo methodArtigo de periódico1-411510.1093/rpd/nci150https://orcid.org/0000-0003-4023-236X
