“…The number and approximate position of particular deconvolved TL peaks were obtained using the T max -T stop method [31], resulting in five peaks in all, centred at approximately 120, 160, 225, 300, and 340˚C. Similar investigation conducted by this group on the present material, obtained five peaks, centred at approximately 163, 216, 232, 261 and 278˚C [32]. The plot can also be used to gain an estimate of the kinetics of the electron-hole recombination processes.…”

For x- and gamma- irradiations delivering entrance doses from 2- up to 1000 Gy to commercial 1.0 mm thick borosilicate glass microscope slides, study has been made of their thermoluminescence yield. With an effective atomic number of 10.6 (approximating bone equivalence), photon energy dependency is apparent in the low x-ray energy range, with interplay between the photoelectric effect and attenuation. As an example, over the examined dose range, at 120 kVp the photon sensitivity has been found to be some 5× that of 60Co gamma irradiations, also with repeatability to within ~1%. The glow-curves, taking the form of a single prominent broad peak, have been deconvolved yielding at best fit a total of five peaks, the associated activation energies and frequency factors also being obtained. The results indicate borosilicate glass slides to offer promising performance as a low-cost passive radiation dosimeter, with utility for both radiotherapy and industrial applications.

“…One of the most desired dosimetric characteristics, whether for plastic or any other detector, is the prevalence of linearity of response regarding the absorbed dose profiles. In several circumstances, linearity response can be found directly from the raw data without preprocessing [21][22][23][24][25]. Although the direct method cannot identify linear behavior, other methods can be used to transform the raw data into a different metric space.…”

Dosimetric evaluation is indicated for material characterization seeking to identify possible applications; still, proper preprocessing techniques are critical features of this process. This work aimed to determine the linearity response of plastic samples irradiated with gamma rays using the Fourier Transform Infrared (FTIR) measurements. The plastic samples were analyzed using Derivatives and Principal Component Analysis (PCA) methods. They applied linear and Principal Component Regression (PCR) methods to obtain linearity. The methods obtained good results for linearity and also showed the evolution of each technique. In conclusion, the results indicate that the applied methods can be useful in radiation physics and for plastic samples as interesting potential radiation detectors.
