Investigation of enhancement dose of the polymer gel include gold nanoparticles in Megavoltage energy with MRI parameter

The use of gold nanoparticles to increase the sensitivity of polymer gels is still controversial. The interaction of photons with gold nanoparticles may lead to an increase in the dose of the polymer gel. In fact, according to the emitted photon energy and atomic number of gold nanoparticles, photon energy less than 0.5 MV could result in photoelectric interaction which in turn might be raise the energy absorbing material.
