AB  - Three-dimensional printing and casting materials were analyzed by prompt 
      gamma-ray activation analysis (PGAA) to determine their suitability as human 
      tissue surrogates for the fabrication of phantoms for medical imaging and 
      radiation dosimetry applications. Measured elemental compositions and densities 
      of five surrogate materials simulating soft tissue and bone were used to 
      determine radiological properties (x-ray mass attenuation coefficient and 
      electron stopping power). When compared with radiological properties of 
      International Commission on Radiation Units and Measurements (ICRU) materials, it 
      was determined that urethane rubber and PLA plastic yielded the best match for 
      soft tissue, while silicone rubber and urethane resin best simulated the 
      properties of bone.
