Determination of the scattered radiation at the neutron calibration laboratory of IPEN using the shadow cone method. In: INTERNATIONAL NUCLEAR ATLANTIC CONFERENCE, October 22-27, 2017, Belo Horizonte, MG. <b>Proceedings...</b> Rio de Janeiro, RJ: Associação Brasileira de Energia Nuclear, 2017. Disponível em: http://repositorio.ipen.br/handle/123456789/28274.http://repositorio.ipen.br/handle/123456789/28274Because of the increase in the demand for the calibration of neutron detectors, there is a need for new calibration services. In this context, the Calibration Laboratory of Instituto de Pesquisas Energéticas e Nucleares (IPEN), São Paulo, which already offers calibration services of radiation detectors with standard X, gamma, beta and alpha beams, has recently projected a new test laboratory for neutron detectors. This work evaluated the contribution of dispersed neutron radiation in this laboratory, using the cone shadow method and a Bonner sphere spectrometer to take the measurements at a distance of 100 cm from the neutron source. The dosimetric quantities Ḣ*(10) and Ḣp(10) were obtained at the laboratory, allowing the calibration of detectors.openAccessneutron sourcescalibrationneutron activation analysisneutron detectorsradiation scattering analysisbonner sphere spectrometersamericium 241shadow effectbrazilian cnenTexto completo de eventohttps://orcid.org/0000-0002-7362-2455
