The mass attenuation coefficients (mm) of polyethylene glycol (PEG) of different molecular weights (1000e200,000) were measured using single-beam photon transmission. The X-ray fluorescent (XRF) photonsfrom Zinc (Zn), Zirconium (Zr), Molybdenum (Mo), Silver (Ag) and Cadmium (Cd) targets were used todetermine the attenuation of gamma radiation of energy range between 8.67 and 23.19 keV in PEGsamples. The results were compared to theoretical values using XCOM and Monte Carlo simulation usingGeant4 toolkit which was developed to validate the experiment at those certain energies. The massattenuation coefficients were then used to compute the effective atomic numbers, electron density andhalf value layers for the studied samples. The outcomes showed good agreement between experimentaland simulated results with those calculated theoretically by XCOM within 5% deviation. The PEG 1000sample showed slightly higher mm value compared with the other samples. The dependence of thephoton energy and PEG composition on the values of mm and HVL were investigated and discussed. Inaddition, the values of Zeff and Neff for all PEG samples behaved similarly in the given photon energyrange, and they decreased as the photon energy increased.
Abstract
The mass attenuation coefficients (mm) of polyethylene glycol (PEG) of different molecular weights (1000e200,000) were measured using single-beam photon transmission.

The results were compared to theoretical values using XCOM and Monte Carlo simulation usingGeant4 toolkit which was developed to validate the experiment at those certain energies. The massattenuation coefficients were then used to compute the effective atomic numbers, electron density andhalf value layers for the studied samples. The outcomes showed good agreement between experimentaland simulated results with those calculated theoretically by XCOM within 5% deviation. The PEG 1000sample showed slightly higher mm value compared with the other samples. The dependence of thephoton energy and PEG composition on the values of mm and HVL were investigated and discussed. Inaddition, the values of Zeff and Neff for all PEG samples behaved similarly in the given photon energyrange, and they decreased as the photon energy increased.
