Características dosimétricas de fuentes isotópicas de neutrones

Abstract

Using Monte Carlo methods, the neutron spectra produced by $^{252}$Cf, $^{252}$Cf/D$_{2}$O, $^{241}$AmBe, $^{239}$PuBe, $^{140}$LaBe, $^{239}$Pu$^{18}$O$_{2}$ and $^{226}$RaBe were calculated. The mean energy and the dosimetric features for each source were determined. The calculated dose were H, H*(10), H$_{p,slab}$(10,0$^\circ)$, $E_{AP}$ y $E_{ISO}$. During calculations the sources were modeled as point-like and the dosimetric features were determined in vacuum. For $^{239}$PuBe and $^{241}$AmBe neutron sources the Monte Carlo calculations were carried out using the actual dimensions and their dosimetric characteristics were evaluated inside of an air-filled region. These results were compared with experimental data.
