Monte Carlo N-Particle Method Dose Calculations Using Gold Nanoparticles in Cobalt- 60 Radiation Therapy


In this paper, amplification in dose due to the presence of gold nanoparticles was quantified using Monte Carlo N-Particle (MCNP) simulation. Simulation models included the irradiation of a 30 cm × 30 cm × 15 cm pure-water—volume phantom with a beam of 1.17 MeV and 1.33 MeV Cobalt spectral emissions as source. Planar and concentric water panel detectors placed at a distance of intervals of 0.1 cm from the center and the surface were used to obtain radial and depth doses within. To verify the accuracy of the program codes and the phantom specifications used, baseline data using water phantom were compared to calibration data. Read More
