Resumo
Radiation dosimetry for medical and industrial purposes has increasingly evolved over the last few decades with the
introduction of various new detectors. Depending on the properties exhibited for radiation dosimetry, some detectors
present their applications in a specific area. From a physics point of view, an ideal dosimeter should be able to
measure absorbed dose. In this work, synthetic materials based on polybutadiene rubbers (PBR) were proposed as a
new class of radiation detectors. The influence of radiation dose on their properties has been investigated for application
in radiation dosimetry. The rubber samples were exposed to absorbed doses from 10 Gy up to 250 Gy, using a
60Co Gamma Cell-220 system. Their responses were carried out with a Fourier Transform Infrared (FTIR) Spectrometer
to investigate the presence of absorbance peaks. The results suggested the existence of a relationship between
the absorbed doses and the absorbance peaks associated with stretching (1300-1200 cm-1), deformation
(1450-1340 cm-1) and vibration (1500-1400 cm-1) processes in the material.
