This document discusses a study that fabricated paraffin wax phantoms to measure absorbed radiation doses and compare them to other phantom materials like water, solid water, and PMMA. Two paraffin wax phantoms were made, one with bubbles and one without, and both were scanned using a CT scanner. Absorbed doses were measured in the phantoms using ionization chambers and a linear accelerator. Scaling factors were calculated to determine the absorbed dose in different phantoms relative to a water phantom. The results found paraffin wax phantoms had the lowest deviation from water, around 1%, while PMMA had the highest at over 5%. Paraffin wax phantoms were determined to be a suitable
