VEGA-CARRILLO, H.R et al. Neutron room return effect. Rev. mex. fis. [online]. 2008, vol.54, suppl.1, pp.63-66. ISSN 0035-001X.

The coefficient that relates the neutron source strength and room surface area with the thermal neutron fluence rates has been calculated for neutrons whose energy goes from 1 eV to 20 MeV. This coefficient was calculated using Monte Carlo methods for several room's radii where a point-like source was located at the center of the room while detectors were located along the room's radius. Calculations were performed with the room with air and in vacuum.
