Resumo
An alternative simple method to evaluate the L/D ratio of neutron imaging beams is proposed. It is based on the
behavior of the ratio “x/Ut”, which asymptotically tends to L/D for large values of the parameter “x”, that
corresponds to the distance separating a gadolinium test object to the scintillator plane, where its image is formed.
The method was applied to the neutron imaging equipment of the Nuclear and Energy Research Institute IPENCNEN/
SP and the obtained result was L/D = (104 ± 4). The consistency of the proposed method was verified by
comparing this value with those ones obtained by a well - known and established procedure.
