VEGA-CARRILLO, H.R. et al. Características dosimétricas de fuentes isotópicas de neutrones. Rev. mex. fis. [online]. 2005, vol.51, n.5, pp.494-501. ISSN 0035-001X.

Using Monte Carlo methods, the neutron spectra produced by ²⁵²Cf, ²⁵²Cf/D₂O, ²⁴¹AmBe, ²³⁹PuBe, ¹⁴⁰LaBe, ²³⁹Pu¹⁸O₂ and ²²⁶RaBe 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°), E_AP y E_ISO. During calculations the sources were modeled as point-like and the dosimetric features were determined in vacuum. For ²³⁹PuBe and ²⁴¹AmBe 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.

Keywords : Neutron sources; Monte Carlo; dosimetry.
