Abstract
Thin plastic film, based on PVC, is a transparent, low-cost, easy-to-handle material that can be applied as a support containing fibrous, granular, or powdery materials for analysis in order to determine radioactive properties, such as: index of refraction, reflectivity, absorptivity and transmissibility. However, the plastic film itself can substantially interfere with the measurements of the materials that are truly the objects of interest in this analysis. In order to get around this situation, these same radiative properties were analyzed in thin plastic film so that it was possible to compute the interference of the film itself in the final result, for other tests to be done later. The work that follows in a first moment, presenting the used equations, a description about the Perkin Elmer spectrometer model 100 FT-IR & FT-NIR, that was used for the tests, being that the majority of the radiation emitted by the equipment source operates in the infrared band, which is the band responsible for thermal heating, and soon after the tests, the radiative properties of the film were determined.
