VAZQUEZ-LOPEZ, C.; ZENDEJAS-LEAL, B.E.; GOLZARRI, J.I.  and  ESPINOSA, G.. An improvement to nuclear track counting systems using laser light scattering. Rev. mex. fis. [online]. 2011, vol.57, suppl.1, pp.18-20. ISSN 0035-001X.

In this work we present a device to measure the angular distribution of the diffuse optical transmittance produced by etched nuclear tracks in a polyallyl diglycol carbonate (PADC) detector. The device makes use of a stepper motor to move an array of four photodetectors around the sample in 1.8-degree steps. The effect of additional scatterers is reflected in the width at half height of the angular distribution curves. The width at half height was found to be a linear function of the nuclear track density in the range from zero to 2.8x 105 cm-2. An Am-Be neutron source was used.

Keywords : Transmittance; angular distribution; PADC (CR-39); nuclear tracks.
