Measurement of mass attenuation coefficient of paraffin wax by using low energy x-ray

This study explores the mass attenuation coefficient properties of paraffin wax at kilovoltage x-ray energies and compares these properties with those of solid water phantom, water, and Perspex, which are commonly used to mimic human tissue. Using the Half-Value Layer (HVL) method, we determined the...
