A study of photon interaction parameters in some commonly used solvents

Area of Science:

• Medical Physics
• Radiation Dosimetry
• Computational Chemistry

Background:

• Accurate dosimetric parameters are crucial for radiation shielding and medical applications.
• Understanding solvent interactions with radiation across various energies is essential for safety and efficacy.

Purpose of the Study:

• To compute and compare key dosimetric parameters (mass attenuation coefficients, effective atomic numbers, electron densities) for common solvents.
• To analyze the energy-dependent behavior of these parameters.
• To evaluate two distinct methods for calculating effective atomic numbers.

Main Methods:

• Utilized computational methods to determine mass attenuation coefficients, effective atomic numbers, and electron densities.
• Covered a broad energy spectrum from 10 keV to 100 GeV.
• Performed a comparative analysis of two methods for effective atomic number computation.

Main Results:

• Mass attenuation coefficients, effective atomic numbers, and electron densities showed near-constant values for solvents in the 0.1-5 MeV range.
• Significant variations in these parameters were observed at lower (10-100 keV) and higher (5 MeV-100 GeV) energies.
• Observed variations are attributed to the dominance of different radiation interaction processes at different energy levels.

Conclusions:

• The energy dependence of dosimetric parameters in solvents is significant, particularly outside the intermediate energy range.
• Computational studies are vital for predicting solvent behavior under diverse radiation conditions.
• Findings provide valuable data for radiation shielding design and applications in nuclear medicine and industry.
