Resumo
In radiation physics, the study of new alternative dosimeters is of interest to the growing branch of dosimetric
characterization for radiotherapy applications. The goal of this work was to expose bone samples to high doses
and evaluate their linearity response to gamma rays. The Fourier Transform Infrared (FTIR) spectrophotometry
technique was employed as the evaluation technique, and based on the spectrophotometry absorbance profiles
the linearity was assessed based on the following methods: Area Under the Curve (AUC), Wavenumber Method
(WM), Partial Component Regression (PCR) and Partial Least-Square Regression (PLSR) methods. The bone
samples were irradiated with absorbed doses of 10 Gy up to 500 Gy using a 60Co Gamma Cell-220 system. The
results showed, for the calibration curves of the system, adequate linearity on all methods. In conclusion, the
results indicate a good linear response and therefore an interesting potential radiation detector.
