Radiation-induced defects in strontium carbonate rod for EPR dosimetry applications
The radiation-induced defects in strontium carbonate (SrCO 3) rod dosimeter in the dose
range of 2.5 Gy–25 kGy was investigated using electron paramagnetic resonance (EPR)
technique. The EPR spectra of γ-irradiated strontium carbonate (SC) rods exhibit a strong
EPR signal with the spectroscopic splitting g-factor 2.008 and a weak signal at g-factor
2.003. This signal increases with increasing irradiation dose. The dose-response function
has a good linearity in the low dose range of 2.5–500 Gy and slight sub-linearity in the high …
