description |
This study investigates the use of black carbon charcoal as passive radiation dosimetry, offering low dependence
on photon energy and near soft tissue effective atomic number with state-of-the-art techniques. Regression an�alyses have now been conducted using graphite manufactured commercially in the form of charcoal from three
different types: mangrove, coconut, and green charcoal recycled from sawdust, working with photon-mediated
interactions at radiotherapy dose levels. Explorations of changes in Raman spectroscopic characteristics, and
photoluminescence dose dependence have been performed with a focus on the relationship between absorbed
radiation energy and induced material changes, using a 60Co gamma-ray source doses ranging from 0 to 10 Gy.
Raman spectroscopy has established to be an effective method for exploring defects in carbon-based materials
due to its high sensitivity, most commonly focusing on the use of ID/IG parameter. While photoluminescence
analysis will provide information on electronic properties and the band gap energy. The crystal structure of the
black charcoal samples was characterised using X-ray diffractometry, with the goal of determining the degree of
structural order, atomic spacing, and lattice constants of the various irradiated charcoal samples, supported by
crystallite size assessments. The findings of this study could pave the way for a low-cost yet highly effective
system for studying radiation-induced changes in carbon, as well as offering a viable alternative to current
commercial dosimeters, well suited to applications in radiotherapy. |
