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), Hp,slab (10,0°), EAP y EISO. 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.
