“…The present work is only concerned with the characterization of the GEM-based TEPC using the bare 252 Cf source and the same source located at the center of a moderating sphere of 30 cm diameter of heavy water. The room scatter was known to be important due to the relatively small dimensions of the room and the presence of concrete walls, floor, and ceiling, and it has been fully aaacharacterized [18]. The measurements were conducted on 30 October-1 November 2013.…”

“…Based on results of the test, we obtained the dose-equivalent rates presented in Table 3. The expected dose rates are based on data from Atanackovic et al [18]. For the bare 252 Cf source on 1 January 2012 the measured ambient dose equivalent was 2770 μSv/h at the distance of 0.8 m from the source.…”

“…Neutron scattering on deuterium 1 is one of the simplest cases of the many body problem in nuclear physics and, as such, it is a valuable means of investigation of the fundamental interactions between nucleons. It is, moreover, a case study of practical interest for nuclear applications.…”

“…In nuclear engineering, for instance, the interest mainly concerns the operation of heavy-water moderated reactors. In neutron metrology, the n-d scattering cross section is a necessary information as it determines the energy distribution of the D 2 O-moderated 252 Cf fission neutron reference field, which is used for example for the calibration of neutron dosimeters [1]. In detector physics, the thorough knowledge of the reaction is crucial for the proper characterization of C 6 D 6 scintillation detectors, whose response to neutrons depends indeed on n-d scattering [2].…”

“…Esses métodos são baseados na medição direta do espalhamento no ponto escolhido, método é dependente do tamanho do cone de sombra e da configuração experimental (distância de calibração, ângulo de abertura dos cones e espalhamento da sala) e do campo de calibração (distribuição da energia dos nêutrons e a fluência). O cone de sombra deve ser projetado de forma que o seu ângulo não seja maior do que duas vezes o ângulo de abertura do detector, para ele absorver todos os nêutrons diretos e possibilitar que todos os nêutrons espalhados cheguem ao detector, evitando assim a ocorrência de uma sombra(ATANACKOVIC et al, 2015).…”
